Mavic plans its own Road Tubeless wheelset
Filed Under News | Leave a Comment
After posting about the Shimano/Hutchinson wheelset, I came across Mavic’s work on a new road tubeless wheelset. I’ve heard that some riders rode these on this year’s Tour de France.

Stans announces Road Tubeless Conversion Kit at Interbike
Filed Under Gear, News | 1 Comment
At Interbike 2007, Stan’s introduces a tubeless conversion kit for clincher wheelsets. Basically it is the same setup as with his mountain bike tubeless conversion kit. Run a tubeless valve stem, 60 ml of Stan’s sealant, and Hutchinson’s new Fusion 2 Road Tubeless clincher on a solid rim wall wheel like the Mavic Kysrium or Fulcrum wheelsets. Some wheelset will require Stan’s sealing tape. Stan says the key is the new non-stretching carbon fiber bead in the Fusion 2 tire. He cites better air retention and near-instant sealing repair as the main benefits. Reported by Cyclingnews.com
Road Tubeless: A look at Shimano Dura-Ace / Hutchinson combo
Filed Under Gear, News | 1 Comment
Outside magazine has an online feature about the new Shimano Dura-Ace wheelset that can run Hutchinson’s new tubeless tire, the Fusion 2 Road Tubeless.
It sounds really good:
As expected, things were noticeably smoother. Cornering was also more stable than I’m used to, since the lower pressure leaves more tire in contact with the road. I would love to have had a power meter to see if the rolling resistance was really comparable to my normal setup. But in purely subjective terms, I didn’t feel like I was working any harder. The wheels wind up quickly, hold their speed, and are race-day stiff, while the tires offer noticeable handling improvements.
At a claimed weight of 1,560 grams per pair, the 7801’s are about 100 grams heavier than comparable standard wheels. But you more than make up for that by leaving the pump and spare tubes at home. The tires weigh about the same as a standard tire and tube combined, so weight there isn’t a concern. The Fast Air cans are a necessity, though. Without them, the tires lose air in a matter of hours. But with them, you won’t even have to think about your tires.

Ladies love hot bikes. Ladies love pink. So a pink bike is good for anyone. This year’s Speedgoat Bicycle raffle features a decked out custom pink ride with tons of custom colored parts. All proceeds go to the Breast Cancer Fund. Each ticket is $10, so buy your chance today.
This year’s bike features a custom XC frame from BMC, Fox’s 32 Float 100RLC fork and rear shock, pink Chris King hubs, and a SRAM X.0 drivetrain. Other parts were donated by Hope, Oury, Thomson, RaceFace, and Velocity. All in all it will be a incredibly sweet ride for anyone. Just don’t forget to convert those Velocity rims to tubeless. 
I only wish the color was closer to the CK hubs rather than Pepto Bismol.
Would you ride it if you won it?
Cape Epic 2007: Ride tubeless, please
Filed Under News | Leave a Comment
BikeMagic had this great article about the Cape Epic. Riders, Loan Burger and Reynard Van straaten, decide to tackle the eight day grueling race across South Africa. Racing on a wide variety of terrains, Loan rides tubeless, but Reynard doesn’t. Until Loan gets tired of changing flats that is.
We had a nice chat up the hill and so managed to climb the monster - we passed the last water point and only had the “Ou Wa Pad” left to climb. Then it happened. A puncture! Reynard was not riding tubeless, and it was at this stage that he understood why I insisted that he invests in some before the race. He had his first of what would be three punctures during this year’s Epic.
Day two had similar events occur:
Day two was to be the longest stage of this years Cape Epic. And as luck would have it, right on the start line Reynard had his second puncture. So when all the other riders went off we were sitting next to the start line fixing yet another tube. We eventually got going, but had some work to do.
Day three, Reynard gets converted to tubeless:
This time I made sure Reynard was properly prepared, having given him my spare set of tubeless wheels to use. We’re not planning on having another puncture today.
With only one more puncture over the next 5 days, the pair finished a great race. Congratulations!

Bontrager Dry-X 29er tubeless tires reviewed
Filed Under Gear, News | Leave a Comment
Guitar Ted gets some sample Bontrager Dry-X 29ers and gives an initial review:
These are the Tubeless Ready Bontrager Dry X tires. The weight on my samples is 620 grams each, which is super light for a 2.1″ 29″er tire.
Here’s his first impressons of the new tire:
it’s a tight fit! … These tires and wheels are fast!
These are some very light new tires from Bontrager. Things are definitely getting interesting for 29ers.
Mavic and Hutchinson collaborate for 29er tubeless solution
Filed Under News | Leave a Comment
29er lovers will soon have some new toys from Mavic and Hutchinson. Mavic’s new Crossmax 29″ rim, C29ssmax, and Hutchinson’s 29er Tubeless ready Python with the NG’s dual compound technology. Mmm.. fun.
You wished, you whined, you waited… and now the wait is over. Two French companies have again joined forces for another UST tubeless project, only this time the players are Mavic and Hutchinson (instead of Michelin) and the rim is sized for 29″ tires instead of 26″ ones. Part of the long delay in developing the new bits was reportedly due to the lack of a 29″ UST rim and bead standard that all industry players could agree upon, but with that issue settled, the ball is officially rolling.
The new Mavic C29ssmax is essentially a 29″ version of the Crossmax SL: Zicral aluminum spokes are arranged in Mavic’s new Isopulse lacing pattern, and join the milled Maxtal rims to the latest generation of FTS-X hubs. The C29ssmax rims will also use the FORE drilling process to retain a solid (and airtight) outer rim wall. Quoted weights for the set are 1660g and 1745g for the quick-release and 20mm versions, respectively.
The new wheels will be disc-compatible exclusively, and only with six-bolt rotors. However, Mavic will offer both standard quick-release and 20mm thru-axle front wheels. Each version will use a dedicated non-convertible hub in order to optimize spoke flange spacing, and both sets will carry a retail price of US$775.
The Python 29×2.10″ will use Hutchinson’s new Tubeless Ready configuration which incorporates a UST bead with a standard casing. As on other such tires, users can opt for either a standard inner tube or can convert the tire to true tubeless capabilities through the use of an approved sealant (Hutchinson’s own Fast’air, in this case). At 645g and US44.95 each, Hutchinson claims this setup saves as much as 160g per tire as compared to standard UST.
Hutchinson will offer just one 29″ tire for now, but additional models are sure to follow. More importantly, though, the establishment of a true UST standard means that more tubeless 29″ tires will also arrive shortly from a variety of other manufacturers.
