If, like us, you were surprised to find that the top cap bush is NOT included in the full service kit for a Reverb seatpost then this is the solution. Developed with Igus Bearings this custom polymer bush is a direct replacement for the one in your top cap. Simple pop the old one out, press the new one in and you’re good to go.

This bush is compatible with Rockshox Reverb top cap part numbers 11.6818.030.000, 11.6815.010.020 and 11.6815.010.010 and Reverb A1, A2 and B1 seatposts.
