Reverse - Colab Expert Chain Tensioner

SIMPLE JUST GOT BETTER – Chain Tensioner Expert

The Colab Expert Chain tensioner is the newest addition to our Singlespeed drivetrain family. Providing a highly secure, robust and easily-adjustable system of tensioning the chain, designed for freeride / DH level use on full-suspension mountain bikes.

The Expert boasts 15mm of adjustability of the chainline and an adjustable limit stopper, plus a pinch bolt on the mounting bracket and a higher spring tension to keep your chain tight, cutting out chain slap even on the gnarliest of landings. The Expert gives you a quieter, reliable and adjustable single speed setup.

Paired up with our new Expert Singlespeed kits with Sprocket Guides, which act like a chain guide for the rear cog - the chain isn’t going anywhere. Sandwiched between two CNC machined aluminium guide plates, with a refined tooth design, your rear sprocket and chain interface is locked in place rock solid, no matter how rough it gets or how hard you’re cranking into That 50 footer.
