he engineers at Mavic have never met a piece of cycling equipment that they didn't want to improve. In the case of the Yksion Pro PowerLink Clincher Tire, this meant going so far as designing a tire to work specifically as a rear tire, capitalizing on the use-specific requirements of the point where your power output meets the road. For ultimate functionality, pair it with the Yksion Pro GripLink tire up front. The PowerLink technology at the heart of the Yksion Pros results in softer, tackier shoulders and a hard, durable center strip. This makes for more confidence in corners, more rolling efficiency and better power transfer in the straightaways, and a longer tread life. An additional anti-puncture layer under the tread helps prevent punctures, and the tire's durability is further boosted by its 127 TPI casing, which is less supple than some tires but pays off in the PowerLink's longevity.
