When only the best will do

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.

The top-of-the-line seat mast cap includes 10mm oval saddle clamp ears, so it’s ready to use with most carbon frame saddles.
