Crossroc 27.5" WTS - Pair - OE

A fine intersection between wheel sizes (fitting in nicely between 26ers and 29ers) and value (stacking up with equal consideration to weight, strength, and value), the Mavic Crossroc 27.5" WTS is a wheel and tire system designed to confidently crush a wide variety of terrain under a wide variety of riders.

The Crossroc WTSs' S6000 aluminum is slightly heavier than the Maxtal aluminum used in Mavic's top-end wheels, but it still makes for more than enough power transfer for those of us who are self-sponsored. The spokes are also a step down from the top-end models, using steel spokes with brass nipples instead of the Zicral aluminum found on Crossmax builds. These small differences result in the paltry weight addition of around 150 grams — hardly something to lose sleep over. Compared to the Crossroc XL 27.5s, they lose 1 millimeter of width and a claimed 60 grams of weight, so you'll accelerate with more snap out of switchbacks and enjoy less inertial resistance on climbs.

Mavic's Transfer System 2 (TS2) hubs are the main focus of the Crossroc WTS wheels. As opposed to the Crossmax's four pawl setup, the Crossroc's freehub uses two pawls that engage simultaneously. The hyperglide body that comes standard on the rear wheel is compatible with all Shimano mountain groups and SRAM's nine- and ten-speed mountain groups. It can be converted for use with SRAM's 11-speed groups using an optional kit. The rims get Mavic's H2 treatment, which consists of hammer hardening the rim to reinforce the points where spoke tension is greatest.

The Crossroc 27.5 WTS rocks Mavic's UST system, so you can run them with tubes or you can take advantage of the smoothness, low-weight, and fewer flats associated with a tubeless ride. The included Crossroc Roam tires have a middle-of-the-road 60a compound for all-around functionality that's further buttressed with an additional layer to ward off flats. They're also Mavic's lightest tire, which complements the rim's light weight.
