Description
The Reverse Colab Expert Chain Tensioner is the ultimate solution for riders looking to simplify their drivetrain without sacrificing performance. Designed to replace your rear derailleur, it delivers a clean, secure single-speed setup with exceptional chain retention—perfect for dirt jump, slopestyle, and hardcore park riding.
The Expert version takes things further with tool-friendly adjustability and increased durability for the most demanding use. With 15mm of chainline adjustment available by loosening a single bolt, dialing in perfect alignment is quick and easy—no need to remove the tensioner. An adjustable limit stopper, pinch bolt mounting system, and higher spring tension ensure the chain stays put, even during heavy impacts or when removing the rear wheel.
Precision-built in Germany from durable aluminum, the Colab Expert is compatible with 9, 10, and 11-speed chains and works with 13–17T cogs, making it a versatile upgrade for a wide range of builds. At just 146g, it’s lightweight, tough, and ready for riders who demand simplicity and reliability.
