Abstract

An anti-chain wrap device for bicycles has a short mounting plate with large fastener holes for universal adjustments in the plane thereof and a clamp plate fastener with conventional fastener holes. Chain lifter fingers for contacting chain stuck on a chainring have portions bent out of the plane thereof to avoid interference on chainrings having extra teeth thereon. The fastener plate may have a fender mounting tab thereon as well as a control cable guide.
