The Gusset Bachelor Fixed Single Speed Tensioner is an essential component for cyclists converting a geared bike to a single-speed setup or managing chain slack on rigid frames. Designed for those seeking a clean, minimalist drivetrain, it provides consistent chain tension and reliable operation; however, it is specifically engineered for quick-release skewer systems, which may limit compatibility with thru-axle or bolt-on axle frames.

Yes, it is designed specifically to allow single-speed conversions on frames with vertical dropouts that lack horizontal adjustment.
While it can be used with a multi-speed chain, it is optimized for standard 1/8" or 3/32" single-speed chains.
The tensioner mounts to the QR skewer, so as long as your frame and hub setup allow for it, it should not interfere with standard disc brake configurations.
The unit weighs 95 grams, including all necessary fittings.
No, it includes a replacement end nut to work with your existing quick-release skewer, but the skewer itself is not included.
Check the chain line alignment; ensure the roller is centered correctly on the chain and verify that the sealed bearing is rotating freely.
Ensure the pivot and lock mechanism is tightened sufficiently after setting the tension and check that the axle nut is properly torqued against the dropout.
To install, first remove your existing rear derailleur and set your preferred gear ratio. Slide the Gusset Bachelor onto the quick-release skewer using the provided replacement end nut. Position the tensioner arm so the PU roller pushes against the chain to create the necessary slack management. Once the desired tension is achieved, use the lock mechanism to secure the arm in place.
Compatibility Note: This device is intended exclusively for standard 9mm quick-release systems. It will not work with bolt-on hubs or modern thru-axle frames.
Care Instructions: Periodically inspect the PU roller for signs of wear and ensure the pivot bolt remains tight. Because it uses a sealed bearing, the roller is mostly maintenance-free, but wiping away grit and debris after wet rides will extend the life of the roller surface.
