Needed....Comet 20 or 30 series "Tav" set up with metal backing plate. I do not need the aluminum one..due to clearance. It can be new or used. I need one for a 40/41 chain. Worse case I can change it from a 35T if needed. Any help would be appreciated. And yes..this is for a low budget build...so leaning toward used. PM me if you have questions or have one. Thanks :thumbsup:
