Reverse Components Colab Single-Speed Chain Tensioner (SB One Collaboration)
Less complication = More riding time!
That was the primary aim with our SB One collaboration chain tensioner. Bikepark laps, freeride lines, and gravity-focused riders often do not need the complexity or vulnerability of a traditional rear derailleur setup. Combined with a single-speed kit, this tensioner lets you keep your drivetrain simple, quiet, and hassle-free all season long. No more waiting at the bike shop while your friends are back on the chairlift for another lap!
The chain tensioner mounts directly to your rear derailleur hanger, routing the chain cleanly through dual jockey wheels to provide a tight, smooth, and secure setup on rough terrain.
