FAQs

It uses a spring-loaded arm to press against the chain, taking up slack and keeping tension consistent during pedaling.

Single-speed, coaster-brake, and internal-gear bikes often require one because they lack a derailleur to manage chain slack.

Yes. Most models bolt to the derailleur hanger or frame dropout with basic tools and no special skills.

Yes. The unit mounts on the non-drive side or under the chainstay, leaving disc rotors and calipers untouched.

Inspect before every ride and after washing the bike; adjust if the chain sags more than half an inch.
