Mavic XA Pro Carbon 27.5in Boost Wheelset

While it's billed as a traditional trail wheel, Mavic's XA Pro Carbon 27. 5in Boost Wheelset is actually anything but traditional. Which is saying something, considering that we're discussing a brand that has become synonymous with tradition while North American wheel manufacturers blasted off into the stratosphere of wildly unchecked innovation. Instead, Mavic sticks with what works, and the XA Pro Carbon indicates that the brand is finally comfortable enough with carbon technology to trust a full carbon trail wheel for the kind of abuse that favors the latest breed of slack, 5in all-mountain bikes. In typical Mavic fashion, the XA Pro Carbon wheels are shot-through with an expansive list of technologies whose ultimate aim is to increase drive stiffness without taking away from the rim's slightly compliant bump absorption-- speed that privileges comfort. Or comfort that privileges speed, if you'd prefer. Ultimately, the wheels strike one of the best balances of efficiency and cushion in the trail market, and they do it while foregrounding Mavic's insistence on safety and reliability. Despite that staid approach, the XA Pro Carbon does represent a pretty drastic change to Mavic's mountain wheel philosophy, so there's a lot to cover; however, since the wheels are built with one of Mavic's first full carbon rims, that seems the most appropriate place to start. The rims feature a lay-up that targets radial flex (read: squishy cushion for unruly runs) in order to balance the inherent lateral stiffness of carbon with the forgiving vertical compliance of low-profile alloy rims. We like stiff wheels while hammering, but wheels that are too stiff presents issues beyond just comfort. Cushion aside, the lay-up's real benefit to aggressive trail riders is that it helps maintain contact with lumpy terrain by absorbing impact through engineered flex, bouncing less, and keeping tires glued to the dirt. (The spoke material and lacing pattern helps with that, too, as we'll disc...

October's Animal
Most commonly found in the tundra of Rocky Mountain National Park, the pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
