BENEFIT Chain Keeper

This is a convenient item that can be used in times of trouble for BENEFIT. It is a protective part that keeps the chain line in place and prevents the chain from falling off by attaching it to the body of a bike that has been modified to have a single front chain.

We often hear people say, "I'm worried about the front chain falling off" after modifications have been made to the bike. Since the price is relatively reasonable, you can install it right away and eliminate the worry of chain drop!

Shims are included, so either 31.8mm or 34.9mm seat clamp diameter can be used.
