These track/pista/single speed drop outs are direct copies of Zeus track drop outs. These are cut from 3/16” plate 17-4 stainless steel. This makes the significantly stronger than the normal mild steel all drop outs have been traditionally made with. I am selling these in sets of 4 front and rears and only rears in separate auctions. There are two versions of the rears with and without cut outs. This auction is for a set of rear with cutouts.
