Construction: OCLV aero shaft and head. Forged alloy saddle clamps. 2-bolt micro-adjust head mechanism with thumb wheel angle indicator for precise angle adjustment. The unique clamp shape with spring assist allows for super-easy saddle changes. Compatible with standard and oversized carbon saddle rails. A longer bottom clamp better supports saddle rails - shorter top clamp allows plenty of fore-aft adjustment. 15mm offset has a reversible design so it can be run in the forward position.
