Innovative Two-Piece Design
Unlike conventional headset spacers, Trek's two-piece split construction simplifies servicing and cockpit adjustments.
The spacers can be installed or removed without disconnecting hydraulic brake hoses or electronic shifting cables, saving time during maintenance while protecting your fully integrated cockpit from unnecessary disassembly.
This practical design makes workshop servicing significantly easier while maintaining the clean appearance of modern integrated road bikes.
Designed for Fully Integrated Cable Routing
The Aero RSL cockpit has been engineered to deliver maximum aerodynamic efficiency through seamless cable integration.
These headset spacers work alongside the RCS headset system to keep brake hoses and electronic cables neatly routed through the headset, preserving the smooth, uncluttered profile that reduces aerodynamic drag while protecting internal components from dirt and moisture.
The result is a cockpit that performs as well as it looks.
