With the introduction of the new Rockshox RS1 fork, SRAM is looking to make a serious dent in the lucrative and fast paced world of XC racing.
So to compliment their innovative new wonder fork, they’ve created a brand new set of XC racing wheels called the Rise XX Carbon. These feather light wheels weigh 1285 gm and are available only for 29″ bikes, because the large majority of XC racers prefer that wheelsize.

So how will these wheels help you reach the top of the podium?
There are many important components to building a good wheel, but low rotational weight is the most important for XC racing. In order to achieve the lightest weight rim possible, the engineering team developed a carbon tuned rim built for tubular tires. By optimizing the rim for tubulars, SRAM were able to product a 29er rim that weighs a mere 325 gms!
The rear hub is built using their double time technology, which uses 4 pawls ratcheting across 26 teeth, for a healthy 52 points of engagement. Both hubs have high flanges, for increased stiffness and riding precision.
The Rise XX wheels will also be available with the massive predictive steering hub required to utilize the inverted RS1 XC fork. Those hubs where developed specifically for the new fork and cannot be converted to any other standard.The standard hubs can be converted to virtually any axle standard.
For comparison, the new Enve M50, which is their dedicated XC rim that also launched today, weighs roughly 5 grams more a rim. Built to DT Swiss hubs, a pair of has a claimed weight that is 4 grams heavier and will retail for $2718.
The expected shipping date is May 4th.
