Essential Chain Tension for Single-Speed Brompton Folding Bikes
The Brompton Advance Single Speed Chain Tensioner is designed for 4-speed (actually single-speed internal gear) Brompton folding bikes to maintain proper chain tension and prevent the chain from coming off the sprocket. This handy device helps you avoid interruptions during your journey by keeping your chain tight while still allowing your Brompton to fold smoothly. The chain tensioner attaches to the rear frame where it automatically maintains proper tension without the need for a derailleur system.
Suitable for use with MK6 (Advanced) drivetrains and chainring sizes of 50T or 54T, this replacement part is essential when your original tensioner shows signs of wear and tear after lots of use. Made by Brompton to their exacting quality standards, the Advance Single Speed Chain Tensioner ensures your Brompton keeps moving smoothly so you never need to stop and fix a loose chain. Compatible with 10-speed hollow pin chains and Advanced RF (Mk6) drivetrains, this is the genuine Brompton replacement part that maintains the reliability and performance your folding bike is known for.
