Enjoy smooth transitions between gears with our Advance Derailleur Chain Tension. Brompton advance chain tensioner is a tool to help you with changing gears on your bike so you can cycle more efficiently and avoid your chain from falling off. A derailleur moves the chain into a different sprocket when you make the signal to change gear, which alters the tension in the gear cable so our Advance Derailleur Chain Tension forms part of a whole gear-changing system on your Brompton.
The advance chain tensioner has been designed specifically for the Brompton folding bike and includes the following components: 1 x Advance Chain Tensioner, 1 x Counter-sunk Screw, 1 x Counter-sunk Nut. This combination delivers an easy way to adjust the chain tension without requiring any specialist tools. Our Advance Derailleur Chain Tension is compatible with Advanced RF (MK6) with a chainring size of 50T/54T.
Tackle inclines and maintain a comfortable pedal speed during every commute or cycle exploration with our Advance Derailleur Chain Tensioner.
