The Mavic Crossmax Elite 27.5 Front Wheel is the result of the brand's years of analyzing wheels and their performance to build a wheel that is superlight and creates huge performance gains. The Crossmax Elite 27.5 is Mavic's lightest aluminum rim and was built for a Boost hub spacing. This rim is engineered with ISM 4D technology, which machines the rim between each spoke hole to minimize weight without compromising strength as well as a 22mm wide (internal) rim which features a UST tubeless system for improved traction, reduced risk of punctures and easier tire mounting. The Crossmax Elite 27.5 features QRM hubs that deliver smooth, long-lasting performance, and a fast-engaging ID360 freehub that enhances a quick and dynamic feel that will last long in the trails and all your adventures.
