The Colab Expert chain tensioner is the latest addition to the single-speed drivetrain family from Reverse Components. It offers an extremely secure, robust, and easily adjustable chain tensioning system, designed for use in freeride and downhill mountain biking. The Expert features a 15 mm adjustable chainline and an adjustable limit stopper. Combined with the clamping screw on the mounting bracket and increased spring tension, these new features significantly reduce chain slap, even during the hardest landings. The Colab Expert provides you with a quieter, more reliable, and adjustable single-speed setup. Paired with the new Expert single-speed cogs and cog guides, which act as a chain guide for the rear cog, the chain stays perfectly in place.
Features
Chain tensioner for single speed, freeride, and bike park
Anti-slip washer: creates traction and prevents your tensioner from slipping under vibrations (between the bolt and tensioner interface)
Adjustable limit stopper: the new oversized stopper keeps your tensioner in place and functional even under extreme compressions. It also helps set positioning with the placement screw and prevents movement under heavy impacts.
Placement screw: the tensioner comes with a bolt that allows for easy optimal positioning and enables removal and reattachment without losing its setup.
Locking bracket: adjusts chainline as well as the position of the tensioner and is oversized for increased durability.
Increased spring tension: holds the tensioner more firmly, reduces vibrations, and minimizes the risk of chain derailment.
Chainline adjustment: a single bolt allows for 15 mm of lateral adjustment for a perfect chainline.
Materials: CNC aluminum and plastic for the jockey wheels.
