Originally developed for the incredibly light Émonda SLR 10, the SLR seat mast cap is the lightest available for Trek bikes equipped with round seat masts.
This high-end cap comes with 7x10mm oval ears, so it's ready for most carbon-railed saddles out of the box but able to convert to 7mm round or 7x9mm ears instead if necessary.
- Lighter than the standard round carbon seat mast cap
- Direct fit on all Trek road bikes with round seat masts
- One bolt head design offers easy fore-aft and infinite angle adjustment
- Includes 10 mm oval saddle clamp ears, 7 mm round ears sold separately
