C3 V-frame time trial unicycle

20241110_141301

I originally built this unicycle to ride in my 24 Hour World Record event, but unfortunately Guinness does not allow custom equipment, so it has to sit on the sidelines. The V-unicycle was made by Anders Waiker for C3 cycles, a custom frame builder who also built my C3 stainless racer,  I talked about this years ago on the unicycle forums, but others made the leap well before me, so I’m playing catchup!
The idea with a V-frame is that it allows the rider to distribute their weight like a bicycle, which means a less upright position, less saddle soreness, and greater power.   For distance riding, most riders use long extension handlebars to achieve this, but it is not the greatest engineering design, as there is nothing to brace the bar.  Luckily, for my 24 Hour Record attempt, the Mad4One handle-saddle is sufficiently stiff that I can use the TT position without any flex.  However there is minimal adjustability and the cockpit is very narrow.  Here is a comparison of the two setups:

My v-frame is made from cromoly steel with fillet brazed joints.  The small diameter tube resulted in some flex, so we brazed a second set of tubes to stiffen things up.   There is a steel tube which sits in the front fork. This can be moved up or down to adjust handlebar height.  Likewise, I’m using a regular bicycle stem which means some adjustability in terms of reach. 
I omitted disc brake tabs- it’s not something I use unless on a geared unicycle or riding off-road.  This is purely for time-trialing!  Finished off with a bright yellow paint job and it looks as fast as it rides.

It takes a while to get used to the TT-position, but once you’re familiar, it allows you to pull on the bars for power, and steer by weighting the arms.   The balance axis is quite different to a regular unicycle, but similar to my 24hr world record unicycle with Mad4One Handle-saddle with URSLI extension bar.  It takes a few rides to get used to free mounting and going over bumps.  Once this ‘clicks’ into the brain, the TT position is comfortable and very fast.  This years’ unicon 54km road race was won on a V-frame, so there has to be an advantage!
Overall weight is slightly higher than a single fork unicycle, but it’s not noticeable.  The stability and adjustability of the riding position more than makes up for this. 
I’m disappointed it can’t be used for my 24 Hour record attempt, but I will be training on this unicycle and you may well see me at the next Unicon on board a V-frame.

Continuous glucose monitoring (CGM)

One of the benefits of working in the medical industry is that from time to time, you get to play with some cool toys.  Continuous glucose monitors (CGM) have been around for a few years.  They are now funded for Type 1 diabetics in NZ, so the local drug company dropped some off for my doctors and nurses to trial for 2 weeks.


In the past I’ve looked at heart rate monitoring, power monitors etc.  Most of the time, I don’t find it interesting or useful to continue.  I was glued (literally!) to my CGM monitor for 2 weeks!  I’m not diabetic (my HbA1c is 33) but it was fascinating.  Diabetes is classified as HbA1c 50 and above.  However, this doesn’t reflect day to day, or hour by hour fluctuations in blood sugar.  


My CGM is a basic Freestyle Libre 2, made by Abbott.  It attaches to your arm via a thin filament that comes out of a plastic disc.  Each disc costs NZ$106 and lasts for 2 weeks.  It runs on bluetooth, and gives you glucose readings each minute on a phone app.

The eye opening thing for me is how variable my blood sugars are after meals.  If you do a traditional finger prick blood sugar test after eating, you have no idea where on the curve the result sits. The blood sugar could still be going up, on the way down, or yet to rise!  I can see how useful it is for Type 1 diabetics, because they titrate their insulin to the blood sugars result.   Type 2 diabetics tend to start on oral agents, but if they are on short/medium acting insulin, it would also be very helpful.  It also provides an idea of how particular foods affect their blood sugars.


Back to this being a unicycle blog….of course I had to try it in training! The other big eye opener for me is the effect of exercise on blood sugar.  It completely flattened my sugar peaks.  
This is a day showing sugar peaks with meals.  I missed breakfast, and was mostly sedentary, seeing patients in clinic:

11 Oct

During my 2 week trial, I ate high carb and low carb meals, high GI and low GI, and they all resulted in a similar rise in blood sugar.  So much for the glycaemic index!


This is what happens when I exercise- the day I rode 265km for 12hrs (0800-2000hrs) for my practice 12/24hr record

12 Oct

I had oat porridge and coffee at 7am for breakfast.  My ride started at 8am, just when my sugars should be rising.  Instead, it remained flat, and stayed that way for 12hrs.  During this time, I ate a large cheese sandwich, 100g of chocolate, 3L of chocolate milk, 1 muesli bar, 1 apple, 1 1/2 meat pies.  They did nothing to my sugars. It was not until I went home, had a shower and dinner, that my sugars started rising.


The same effect happened on other days- if I exercise within an hour of eating, my blood sugar remains very flat.  The effect even lasts into the next day, when the sugar peaks are at lower level than I would expect.
Take home message- eat what you like (within reason), but exercise after eating to keep sugars low.   How this translates into long term health for non-diabetics is hard to know, but it seems to make the insulin/glucagon balance more effective.  That can’t be a bad thing.  


In terms of performance, I haven’t used it enough to make a sensible conclusion. I did notice a power drop after I had lunch (approx 12pm) during my 12hr ride, but my average sugars also dropped from the low 6s to the mid 5s.  Perhaps I didn’t eat enough, or there was a surge of insulin that drove the sugars down.  I might just have to do another CGM trial to find out!

Malaghan Institute

When you’re a kid with dreams of saving the world, it’s worth a revisit even when life takes you down a different path. These days, I do my best for the person in front of me as a family doctor, but back in my youth, I spent a year in a cell signaling laboratory doing a BMedSci research degree.

I never became a scientist, but I can support their work vicariously. The Malaghan Institute is a Wellington research institute studying immunology and immune therapy, and applying this to allergy/inflammatory disease, cancer and infectious disease. Their research is world class and covers the spectrum from basic science to clinical trials.

This is the charity I will be raising money for with my 24 Hour Unicycle World Record Challenge. Please sponsor me and help our clever scientists come up with solutions and understanding of life’s most challenging problems.

My target is to raise $5000. That’s $10/km for 500km!

The 24hr dress rehearsal

I did a 12 hour practice ride for the 24hr record to get used to my equipment and see how far I could go. It’s hard to know how comfortable your setup will be until you’re in the saddle for a few hours, so it was an important part of my preparation. I rode my Triton 36 with Mad4One long handle-saddle, 100mm cranks on a Braus36 carbon rim/ Nimbus Nightrider lite tyre. It seems to be a fast setup, and in practice, I can wind it up to 27km/hr when riding a brisk pace.

My spare wheel- the Mad4One Unicorn 36 carbon rim/ Vee T-monster tyre is the same weight, but has greater rolling resistance. It would be an amazing wheel for gravel/off-road, but on sealed surfaces requires more concentration to keep in a straight line. It is also about 5% slower than the Nightrider, although the gap is narrowing as the tyre knobs wear down.

I started the day with porridge, my usual pre-race meal. A coffee to warm me up and then I headed down the track for an 0800hrs start. It would be a long day, but I had plenty of food/water to keep me fueled! I kept track of progress on my phone Strava, as well as my Lezyne Mega XL GPS computer. It was also a test to check battery life, especially bluetooth headphones and internet enabled on my phone. As well as this, I was trialing a Freestyle Libre 2 continuous glucose monitor, which gave me up to date readings on my blood sugar. A very interesting device which I will do a separate blog post about.

My legs felt good, and off I went! I knocked off a few laps cruising at 25.5km/hr. The strategy is simple- try to use as little energy while riding at 25km/hr for as long as possible. I suspected that my speed would drop to 20km/hr once fatigue sets in, but if I had enough buffer, it would give me confidence for the world record.

In my practices rides, there is a magpie who has been divebombing me from the trees. Today proved no different. The first few hours involved plenty of swoops and the occasional whack. Luckily my helmet offered good protection. After a hard whack the bird would take a break, but it always came back for more!

Now for most people, riding around in circles for 24hrs would be regarded as mind-numbing. I keep getting asked what I listen to. Previously, I had Spotify playlist, which was great…for about 30min. The problem is that music tends to dictate your tempo. There are various pump-me-up songs on the playlist, which is extremely fatiguing to listen to, and wasn’t in sync with my deliberately relaxed riding pace. This time, I set my phone onto national radio (RNZ), and listed to the Saturday broadcast. It was interesting enough- they interviewed a guerilla gardener and a movie producer. The sound of voices is an improvement over music, but still left me mentally fatigued. I turned it off after 5-6hrs. It will be fine to listen to for 2-3hrs at a time. When I do distance rides like Lake Taupo Cycle Challenge or Tour Aotearoa, I found it most relaxing to let my mind wander. Daydreaming is a very effective strategy for distance riding.

I was able to cruise at 25km/hr for 4hours before having a quick lunch break at 12pm. I scoffed down a cheese sandwich, chocolate milk and chocolate, all the time wary that my average speed was dropping. Luckily I eat fast and after 5min I was on my way again.

The post-prandial dip kicked in after lunch, and I suddenly had a power deficit. Interestingly, my blood sugars also dropped from averaging mid-6s to the low 5 mmol/L despite the food intake. My average speed starting dropping into the 23-24km/hr range.

It was a hard few hours from 12-3pm. At one point my legs locked on the corner and I ended up rubbing myself on the concrete. It looked worse than it was- just a graze on my chin but left blood everywhere!

Anna came by with the kids at 3.30pm with some cheese and steak pies, so it was another chance to stop and down more calories. I normally eat fast, but it still took a lot of effort not to choke whilst being mindful of the clock.

I hit 140km at the 6hr mark, which meant that my target of 250+km at 12hrs was achievable. The next 2hrs was difficult, but once I got to 200km (9hrs) I felt relief that I would surpass my target. When I hit 250km, it was enough to turn the grimace into a smile! I still had time to push it further, and stopped the clock on my Strava at 265km. Job done! I’ve proven to myself I can achieve enough buffer within 12hrs to beat the world record and even achieve the 500km target. According to Strava, my riding time was 11hrs44min, so some work required to reduce downtime/breaks.

Total distance (Strava) 265.6km

Total food consumed (riding): 1 large cheese sandwich, 1 1/2 cheese/steak pies, 3L Chocolate milk, half muesli bar, 100g Whittakers almond gold chocolate, 1 apple.

Track Survey

For my 24hr record attempt, I spent considerable time searching for a suitable venue. The Basin Reserve Cricket Ground which I used for my 2005 record has a fantastic 465m circular track, but is much busier these days, both with weekend events and general traffic. I was given one option in early November with no backup for inclement weather, so it was risky proposition.

The ideal venue would be flat, at least 400m in diameter, with no hard corners/turns. I contacted the Newtown athletic stadium, but they do not allow cycling on their running track. There is a concrete path around the athletic field, but with a couple of right angle turns it isn’t really suitable. Then I visited the Hataitai velodrome after seeing photos of their refurbished track. The steep banking was out of the question (I knew this from 2005), but there is a flat concrete track on the infield. Well, it looked good in the pictures. Turns out there are a whole lot of wooden planks across the track- not ideal to change riding surface every few meters. The 333m velodrome is also a bit small to be circling for 24hrs. I looked further afield to Lower Hutt, Upper Hutt and even Masterton. The further I went, the harder it would be to organise support crew and logistics.

I had pretty much settled on the Basin Reserve until I went for a run and came across a concrete track at my old school, Newlands Intermediate. I walked past this field every school day as an 11/12yr old, but it was a looooonng time ago. They have built a 400m concrete track around the bottom field since, and it was a gem of find! The track is smooth, has little traffic, and seemed pretty fast. I was so excited I contacted the principal the next day, who was very happy to help. They’ve been very supportive, and will allow me access to the track and school hall for the attempt. A group of Newlands Intermediate students also came and interviewed me for their newsletter.

One cannot attempt a Guinness and IUF world record without making sure the track is measured accurately. I contacted Cuttriss, a surveying/engineering/planning company, who were involved in measuring the Basin Reserve which I used for my 2005 record. They sent a couple of surveyors, Brett and Ollie, to help me measure the track. I can’t thank you guys enough!

The track came out slightly shorter than expected, at 390.76m on the inner circumference. Not the worst outcome, but does mean a few extra laps to hit my goal.

24hr and 12hr World Record Attempt

It must be the worst kept secret, but many of you will know that I am having another go at the 24 Hour Unicycle Distance World Record. I set the world record on Feb 5th/6th 2005, riding 378.7km in a 24hr period. It was one of the toughest things I’d ever done, and probably something I never thought I’d do again. Well, fast forward almost 20yrs and I’m itching to have another crack.

My record stood for 2 1/2yrs, before Sam Wakeling (UK) smashed it with an incredible 453.8km ride in 2007. It was an amazing feat considering the technology of the time. Enough to put many off the pain and process of attempting the world record.

So what’s changed? The body is 20yrs older, but I’m going faster than ever. At Unicon, our world championships, I came 2nd in the 54km road race and 2nd in the 10km road race. That was for the overall, not my age group. Although I did not ride standard class in 2006, my times are equivalent or better than the year I was the road racing world champion.

The other major change is the technology. While geared hubs have been on the scene for a while now, I never felt they were suited for a long distance challenge. They are good for going fast for a short distance, but I don’t have the power to keep that pace for 24 hours. I will be using a standard ungeared 36″ unicycle, but the wheel is now 2kg (that’s right!) lighter than the wheel I used for my 2005 world record. Where the Coker Airfoil rim and TA tyre was the standard in 2005, now we’re on carbon rims with tyres that are 800g lighter, inflated with TPU tubes that weigh a fraction of butyl inners.

Add in 20yrs of experience pushing my body to the limit, some better handlebars and a comfortable seat, and I think I’m ready for the challenge!

I will be attempting the world record on the 16th/17th November 2024, 0800hrs-0800hrs, at Newlands Intermediate School, Wellington, New Zealand. Keep an eye on the 24hr Record Page for updates.

Unicon 21

I am at Unicon, The Unicycle World Championships and Convention, held every 2yrs.  This is the 21st edition, in the town of Bemidji in Minnesota, USA.  If you are a unicyclist, Unicon is something you must attend at least once in your life!    The 12 day event showcases multiple disciplines within unicycling- from road racing, track events, trials, artistic freestyle, street and flatland, unicycle hockey and basketball, mountain unicycling and much more.

20240714_183920

Not only is it our world championship, but it’s also our world convention. It’s a chance to meet riders from different countries and take part in workshops, social events and rides.  With over 1000 participants, it’s a celebration of all things unicycling.

20240714_175723 20240714_183004

This year’s opening ceremony started with a world record attempt by Jamey Mossengren ‘The Unicycling Unicorn’, trying to ride the world’s tallest (44 foot/ 13.4m) unicycle built by Tommy Miller of the Unicycle Factory.  Jamey didn’t quite nail it during the opening ceremony, but managed to break the record later in practice.

20240714_172422

There was a very cool unicycle museum compiled by Jamey, which had a huge range of historical unicycles, as well as some weird and wonderful creations. 

20240714_152031 20240718_162525 20240718_163053

My favourite event was the flaming puck hockey, hosted by the Bemidji Fire Department

20240723_211501 20240723_213118

My contribution to workshops included running the T-shirt swapping…

20240718_121721

….and a pleasant 64km social ride from Bemidji to Laporte along the Paul Bunyan Trail.  This is an old rail trail that has been paved and now serves as 190km bicycle route through the middle of the state.

20240720_081414 20240720_084142

I also hosted a unitouring workshop, showing off 20yrs of Adventure Unicyclist photos from around the world.  I will post an anniversary album once the compilation is complete. 

In terms of competition, my focus was on the road races, with a bit of Muni and cyclocross thrown in for fun:

10km standard class

The course was along the Paul Bunyan trail next to Unicon headquarters at the Sandford Centre.  The first 8km was almost entirely flat and straight, then turned into a forested area leading to the shore of Lake Bemidji.  

Standard class requires every rider to compete on a 24 unicycle with 125mm cranks.  In other words, roughly half an hour of pedaling like crazy.  The 10km standard is the biggest Unicon competition, overlapping track events in terms of wheelsize/crank standard, so the ultra fast track racers also compete. 

The standard class has always fascinated me. I love the elegant simplicity of the standard, ungeared unicycle, and the skill involved in revving a unicycle to phenomenally high cadences. Since my first Unicon in Tokyo (2004), where I watched Hiroki Shigeno pedaling to victory in an incredible 28min22s, I have wanted to medal in this event. Moving from unlimited class (any size wheel/gear/crank length) 10yrs ago, I’ve had two 4th placings, a 6th and a 13th place, so it was my primary focus during training this year. 

I started in the first wave of elite riders. 3,2,1 go….I can’t sprint like my rivals off the line, but did my best to hang on for the first 2km. We were averaging 21-22km/hr.  As expected, Luis Albers (Germany) was off the front, with a group of Nicolas Chopiné (France), Fabian Toledo (Chile) and myself trying not let elastic band snap. Thankfully, the pace slowed just as Nico and Fabian dropped off the back, and I hung on to Luis for all 8km until the turn down to the lake.  Unfortunately I couldn’t relax enough to spin fast on the slight twisty downhill, and Luis put a gap of 11s on me by the finish.  I rolled across the line in 29min21s in second place, a personal best for the 10km, and my first ever expert medal in the standard 10km!  My transition to a standard 10km racer is complete.

20240716_075511 20240717_220604 20240717_223243

Loop the lake 54km standard class

My next race was the ‘Loop the lake’, a picturesque 2 lap race around Lake Bemidji.  It followed primarily cycle paths with some open road.   I was racing standard class again, but this time the 29″ standard.  You have to keep within the maximal 29″ wheel diameter, but are allowed to choose your crank length. I opted for 80mm, while my competition mostly ran 75mm cranks.  I felt the extra 5mm leverage was good for the bumps and the slight climb on the back portion of the lake.

To say this is a super fun event is an understatement.  The locals and unicyclists were out in force cheering us on, around a scenic and challenging course.

I was immediately in trouble as my younger competitors set a furious pace off the line.  Luis Albers and Aurélien Paulmier dropped the group comprising myself, Souryan Dubois and Nicolas Chopiné within a couple of kms, then Aurélien put on his turbo legs and dropped Luis.  I still had Luis in sight when we hit the road section, and spent most of the first lap trying to inch my way back.   I managed to catch Luis on the straight back to Sandford Centre (the 10km race course in opposite direction), and we rode together to complete the first lap.  Aurélien was already 1min 30s ahead, and so the fight would be for 2nd place.  Luis was the stronger rider- I tried do some work at the front, but mostly did my best to avoid getting dropped by Luis.  We passed a number of unlimited riders, their reactions priceless as we flew past their geared/36″ unicycles.

I upped the pace on the short climbs at the back of the lake, but couldn’t drop Luis, so sat up as we hit the final 8km straight. If I was lucky he might make a mistake- which, although unlikely, was the only way to beat him. As it happened, Luis cramped up 2-3km from the line.  One minute he was there, the next he wasn’t. I didn’t look back as I pedaled as hard as I could to the finish line, coming second in 2hrs4min37s, a very fast 26.0km/hr average speed.  Luis rolled in a minute later, while Aurélien won the race in 1hr58min38s, an incredible 27.3km/hr average speed!  

Another expert silver for the medal cabinet, and an age group gold medal for the 40+ category.  Not a bad day’s work. 

Cyclocross and MUni uphill

I haven’t focused on off-road events for a number of years.  Back in 2004, I came 3rd in the cross country and 3rd in the downhill. The sport is unrecognisable today- the technical ability required in MUni is so much higher.  It doesn’t suit my skillset, which is to pedal very fast, rather than risk life and limb on the typical modern race course.  I was entered in the cross country, but decided to skip it to save my legs for the road races. The uphill race was held at a picturesque local ski resort. I went to check it out, but my unicycle was overgeared (29/125mm) to it make up the hill, so I took my time to complete the race (you are not allowed to walk).  

The cyclocross race was hard but a heap of fun.  Although there was serious racing going on, it is an event where many riders dress up and there is plenty of cheering from the side lines.  It was a Le Man’s start- you run 100m to your unicycle before setting off.  A group of riders decided to do 10 push ups after the start gun! Weird, but highlights the fun nature of the event.  The course had lots of interesting obstacles and a couple of hard climbs. I tried to stay relaxed and enjoy the race. We had people squirting water, showering us with popcorn and cheese balls, an ice block station, as well as a big green dinosaur chasing riders.  I held a decent position and slowly worked my way up the field as it thinned out, finishing a respectable 14th place overall. 

20240724_090308 20240724_091328

Criterium

The criterium was the final road race of Unicon.  It’s a short 800m course with lots of tight turns just like a bicycle criterium. Unlike a bike criterium, which is usually held around a city block, this event was held in a carpark. It allowed for a much twistier course, with multiple 180 degree turns.  I have been working on my cornering, but it remains a weakness, so I wasn’t sure how it would go until I saw the course, set up the night before.

In the standard class, the first five riders from each heat would progress to final.  I was a bit stiff at the start, and struggled to get around the turns as I entered them near the back of the bunch.  Luckily, I caught a number of riders on the straights, and gradually worked my way up the field until I crossed the line in 5th place, booking myself in the final.  

The finals started off somewhat better. I was in 3rd or 4th position going into the first few turns. Unfortunately, a little mistake around a corner saw me flying off to the side, and passed by everyone.  I had to work my way back to finish 7th overall, well off the pace but good enough for an age group silver medal. 

Overall, it was a successful Unicon. I am still up there with fastest unicyclists in the world, and I had a great time catching up with friends and seeing a bit of the American midwest.

Results:

10km standard race: Expert (overall) silver, age group gold

54km free distance road race: Expert (overall) silver, age group gold

Criterium standard race: 7th place, age group silver

Cyclocross: 14th place, age group 5th

MUni uphill: 43rd place, age group 15th

Radio New Zealand interview

My second media interview in 2 days! I talk to Jesse Mulligan from Radio NZ about all things unicycling, and the upcoming world championships and convention.

Radio NZ Interview

The Post article

I had a nice interview with Kim Griggs from The Post, regarding my upcoming trip to Minnesota for Unicon 21, The 21st Unicycling World Championship and Convention. It was a really fun interview although my garage is a bit of a mess!

The Post Article 8 July

Braus 36″ Carbon wheelset with 36″ TPU Pollici inner tube, Nimbus nightrider lite 36″ tyre

These days I spend most of my time riding, touring and racing on 29″ unicycles, but I was super excited when I heard about the new 36″ Braus carbon rim back in 2020. It was less than half the weight of the various aluminium 36″ rims, which is a hefty saving considering the weight of these things!  I had the idea of using this wheel for the Lake Taupo Cycle Challenge, a race I do every year.  My old best time of 7hrs 43min was set on a much heavier 36″ unicycle in 2004, so this was my best chance of breaking the record.  I was also eyeing up Tour Aotearoa, a 3000km ride of the length of NZ.  

The Braus rim weighs in at 546g (claimed), compared with my original Coker Airfoil rim (1232g*).  Another exciting development in the diet stakes was the Nimbus Nightrider Lite tyre, with a claimed weight of 1310g,  compared with the original Nightrider tyre weighing in at 1960g* and my wheel TA tyre 2060g*.  Add to this the spoke count of 32H instead of 36H, shorter and lighter Quax cranks and a set of Ti AEST pedals, and I’d saved over 2kg in rotating weight, and almost 1.5kg of that was in outer wheel diameter where it matters the most.  

20240122_104315 Braus wheelset 20240122_104211 Old Coker Airfoil wheelset

Then Covid happened, and the annual Lake Taupo Cycle Challenge was postponed not once, but twice, meaning that I couldn’t test it in a race where I have almost 20yrs worth of history.  

In 2022, I decided to ride Tour Aotearoa, and this would be the ideal unicycle except for one thing- the tyre is a very tight fit, so isn’t the easiest thing to fix in the event of a puncture.  The rim is drilled for presta valves. and is too narrow to drill for a schrader valve, meaning I had to use a 29″ inner tube stretched to fit, instead of a 36″ tube.  It’s another weight saving, but I pinch flatted two tubes on installation, so was not the best setup if I were to have a puncture on tour.

All this meant the unicycle sat in storage for over 3 years until I came across the 36″ TPU inner tubes by Trentasei.  It has a presta valve (great!) and is made for a 36″ diameter wheel instead of being stretched from a 29″.  I ordered a couple of tubes from Luca at Trentasei36 in Italy.  He was super helpful and the tubes arrived quickly.  Having had bad experiences with ultra light latex inner tubes many years ago, I was sceptical of TPU inner tubes.  The 36″ TPU tube weighed in at 103-108g, another big saving compared with a 29″ CST butyl inner tube (260g), and a 36″ butyl inner tube (524g).  Better still, without the excess stretch of 29″ tube, I installed it easily without damaging the tube. The material, although very light, doesn’t have the balloon like feel of a latex tube. It holds air well (unlike latex), and makes a nice springy, hollow sound when revved up to speed. It not only feels fast, it sounds fast!  As a bonus, the tube rolls up into a small compact bundle, which makes it easy to carry a spare. This has to be the best value upgrade for a 36″ unicycle.

As for the Nimbus nightrider lite tyre, it performs as well as its heavier predecessor, with a grippy tread that handles road camber well. There is plenty of volume, so it’s a comfortable ride. Perhaps a narrower road tyre in future could save even more weight, but it’s easily the best 36″ road tyre currently on the market.

I took the unicycle on a ride through my hilly neighborhood- including a 10-15% gradient climb to my house.  It felt snappy, maneuverable, and accelerated and decelerated like a 29″ unicycle, except I was going at 36″ speed!  I fitted 100mm cranks, where I would normally ride 125s on the same gradient.  It had a similar feel to 29″/89mm.

The best demonstration of the whole system is to race it, and I smashed my 2004 Lake Taupo Cycle Challenge record by 15min!
