Reverse Colab Expert chain tensioner, silver

The Colab Expert Chain Tensioner is the latest addition to our singlespeed drive family. It offers an extremely secure, robust, and easily adjustable system for chain tension, designed for freeride and downhill use with mountain bikes. The Expert provides a 15 mm adjustable chainline and an adjustable stop limiter. Together with the clamp screw on the mounting bracket and a higher spring tension, the new features result in noticeably less chain slap, even during the toughest landings. The Expert gives you a quieter, reliable, and adjustable singlespeed setup. Combined with our new Expert singlespeed sprockets and the sprocket guides, which act like a chain guide for the rear sprocket, the chain stays securely in place. The CNC-machined aluminum guide discs, along with the new tooth design of the rear sprocket, ensure precise chain guidance.

Main features:

• Schnorr washer: Ensures a secure fit and prevents the tensioner from slipping during vibrations.
• Adjustable stop limiter: The new limiter keeps the tensioner in place and functional even during impacts.
• Adjustment screw + stop limiter: Facilitates reattachment of the tensioner to the derailleur hanger, thanks to the previously set stop limiter.
• Mounting bracket: New mounting bracket that allows for a 15 mm chainline adjustment.
• Increased spring tension: Keeps the tensioner tight, reduces chain slap, and minimizes the risk of chain drop.
