Brompton CHAIN TENSIONER ASSEMBLY

The Brompton Chain Tensioner Assembly performs a very important role on a Brompton bike. It keeps the chain tight while folded or unfolded, and most importantly, while folding and unfolding it prevents your chain from dropping and drama ensuing.

It is made from extremely durable Nylon plastic with a strong steel spring to keep things tight and is supplied with new Jockey wheels which ensure you pedal smoothly. Available for Brompton 2-speed and 6-speed bikes, or 1-speed and 3-speed bikes.
