4-Jeri Tensioner

Product code: 10179


On order

4-Jeri Tensioner

- Great value coil sprung single speed tensioner from 4-Jeri products.
- CNC machined main supporting arm offers excellent strength against knocks but keeps the weight low.
- Coiled spring offers high tensioner and is more durable than normal springs.
- Infinitely adjustable and secure chain alignment is catered for by the steel wheel-support arm and locking bolt.
- Generously sized (removable) aluminium cages surrounding the jockey wheel ensure the chain stays where it should no matter how rough the terrain.
- Plastic jockey wheel runs on smooth bushings and is nice and quiet.
- Available in black anodised finish.
- 110g in total.

Additional Information

Please note that we recommend double wheel tensioners for 15T and smaller rear sprockets. This is to ensure a healthy amount of chain wrap and help to eliminate the chance of the chain skipping.

Real simple for ver dropout frames

Posted by Dave

This was so much betters than any other tensioner I have used. Simple to fit and it doesn't interfere with any other part of the drive or frame or hub. Good stuff 4-Jeri, strange name however.

Hi Dave - I'm glad it's worked well for you. The name itself is a play on the word 'Forgery'. Thanks for the review!
