The reason for the easier installation or removal is thanks to Ritchey's unique "press-fit" handlebar clamp. This design improves the interface between the stem and handlebar making attaching the bars to your bike simpler and faster. Also, the forward-facing bolts mean fine tune adjustments are a breeze. Secure and Stable Engagement In addition to easy installation, the WCS 220's clamp design creates a stable and secure bar engagement. This, in turn, increases bar stiffness for more precise handling, sprinting and climbing. Also, the coated CrMo bolts are positioned in alignment with the clamp plate's face for a more efficient hold and reduced flex.
