Weighing in at sub 180 grams, the Next 34in Riser uses a unidirectional carbon fiber weave. By placing the fibers parallel to each other and using resin epoxy to bond them together, they become stronger than woven carbon fiber. In addition, Race Face's bonding process removes any excess resin and air bubbles by compacting the carbon fibers under extreme pressure. This ensures that the bars have no spots that will fatigue. To further improve your confidence, the clamp zones have been additionally reinforced. So, go out and white knuckle your next downhill with full confidence and none of the weight of alloy.
