The REVERSE Colab Kettenspanner is a robust chain tensioner designed to keep your drivetrain running smoothly and securely, even under aggressive riding conditions. Ideal for single-speed setups, dirt jump bikes, and gravity-oriented mountain bikes, this tensioner helps prevent chain slap, derailment, and unwanted chain growth when the trail gets rough. By maintaining consistent chain tension, it improves power transfer and reduces wear on your chain and sprockets, giving you a more reliable and low-maintenance drivetrain.
Built with durability in mind, the REVERSE Colab Kettenspanner typically mounts directly to the derailleur hanger or dropout, making it a great solution for frames without dedicated chain tensioning systems. Its compact design keeps it out of the way of obstacles, while the guide wheel or pulley helps the chain track cleanly over the rear cog. Whether you are building a clean single-speed bike, converting a geared frame, or simply want extra security for park and street riding, this chain tensioner offers a simple, effective upgrade that enhances control, confidence, and overall ride quality.
