Brompton ADV Chain Catcher

Upgrade your Brompton P and T Line folding bikes with the latest version of the Advance Chain Catcher, featuring brass threaded inserts for enhanced durability. This V2 Chain Catcher, now standard on all Brompton bikes produced after July 2023, is essential if you’re fitting a 56T chainring. Designed to keep your chain securely in place over rough terrain, this small component is compatible with 44T, 50T, 54T, and 56T chainrings and is necessary only for bikes with 4 or 12-speed gearing systems.
