This riser handlebar features a triple-butted & tapered alloy construction, which allows it to handle all the abuse that's associated with trail-riding & enduro racing. FSA has also equipped this model with a shot-peened finish, so you can benefit from its incredible stiffness & durability as you attack the trails. Gradient is FSA’s Trail / Enduro Line for those of you that like to crank up the trail & tear it apart on the way back down. Since the introduction of Gradient in 2013, it has been raising the standard on strength & lowering the weight of their trusted components.
