About This Item
Product Description
The Trek SLR Ultra-Light Carbon Seatmast Cap was originally developed for the exceptionally lightweight Émonda SLR 10 and is Trek’s lightest seatmast cap option for compatible road bikes using a round Trek seatmast.
This upgraded SLR version is lighter than Trek’s standard round carbon seatmast cap and features a one-bolt rotary head design for easy fore/aft positioning and virtually infinite saddle-angle adjustment.
This multi-variation listing includes all four length and offset configurations. Each cap is supplied with 10mm oval saddle rail clamp ears for compatible oversized carbon saddle rails.
