Reverse

Colab Pro Chain Tensioner

Reverse Colab Pro Chain Tensioner replaces the rear derailleur with a dedicated single-speed tensioner to simplify the drivetrain and keep chain control consistent when the trail gets rough. Its user-adjustable clutch lets riders fine-tune tension for a quieter ride and more secure chain retention across different frames and suspension setups, without guesswork.

• User-Adjustable Clutch - central Allen-bolt adjustment provides a wide tuning range to dial in chain tension and help reduce chain slap
• Chainline Micro-Adjustment - 15mm of chainline adjustability by loosening one bolt, helping achieve cleaner alignment without removing the tensioner
• Retention-Focused Hardware - adjustable limit stopper plus a pinch-bolt mounting bracket and higher spring tension help keep the tensioner stable, including during rear wheel removal
• CNC Aluminum Pulleys - durable pulley construction designed for long service life under high chain loads
• Drivetrain Compatibility - works with 9/10/11-speed chains and 13–17T cogs for common single-speed setups
• Made in Germany - aluminum construction with precise machining for a secure, serviceable single-speed chain tensioner
