Trialtech Sport Sprung Single Sided Tensioner

Product code: 12959


On order

Trialtech Sport Sprung Single Sided Tensioner

More stuck due October

- Superb quality tensioner from Trialtech, constructed from high grade aluminium alloy, spring steel and chromed steel.
- CNC machined aluminium cage on just one side means the chain can be fitted and removed easily, making rear wheel removal far easier and quicker than double-sided alternatives.
- Two plastic jockey wheels with a multi-coil spring provide high and quiet chain tension that does not reduce over time, combined with the best possible chain contact / wrap around the sprocket.
- Custom design allows the tensioner to be locked securely against the hanger to prevent the main arm from 'bouncing'.
- Finished in anodised matt black with laser etched Trialtech logo on the main arm.
- Sold singly.
- Weight: 104.6g

Hi Pero - The double sided tensioner has been discontinued, so we will not be receiving more of them. Thanks, Mark


Alright guys, Just wondering if this would fit on a normal mech hanger originally designed for geared mechs? Cheers!

Hi Alex - This should fit on that kind of hanger absolutely fine. Thanks, Mark

Hi Nigel - You should be able to use up to a 20t sprocket with this tensioner. Thanks, Mark
