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 Uncategorized | 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.
