Amazing how you forget these two little wheels attached to the rear derailleurs. Mine must have done thousands of miles before I considered changing them trying to get rid of an annoying noise. What a difference they made. Cheap to purchase, easy to install and cured my annoying problem.

Have used these before then switched to aluminium items with centre bearing. They only last a dozen rides before the bearing falls apart. Have now switched back to Shimano as they last at least a full season. Might not add bling to the bike but function & life is what counts.

Bought this as a temporary stop gap waiting for the RD-M800 I ordered from elsewhere to arrive. Fitted OK and works well. Will keep using this and keep the other one as a spare.

This is an excellent product that does not require any attention, it will last years, and will not let you down, after thousands of miles, just fit and forget.
