Regardless of if you have both a race-day and training wheelset, you shouldn"t be eating up your race rubber with base miles. That"s why the Mavic Yksion Comp Clincher Tire is the ideal tire for your everyday wheelset. Designed for heavy duty use, the Yksion Comp features a high density casing that will withstand the rigors of your training schedule without sacrificing any ride quality. This casing adds durability without taking away from the 120 TPI casing"s suppleness. After all, ride quality is still paramount when you"re stacking up training miles. At 210 grams, the Yksion Comp is slightly heftier than other tires in the Mavic line, like the Pro Griplink, but the enhanced durability easily offsets that. Besides, you"re only looking at a 10 gram differential between the Pro series when you run the Comp as a set. Mavic"s all-condition rubber compound and tread expertly blend grip, efficiency, and durability. And the bead uses foldable aramid fibers that are both lightweight and durable. The Mavic Yksion Comp Clincher Tire is available as a 700c tire and in either a 23 or 25cm width.
