I'm new to the forum and have a question about my 1988 (I think, anyway-- could be a 1989) Trek 1200 road bike. I took the front and rear axles apart to redo the cones and bearings, and found that a couple of local bike shops don't carry the right size cones. The original cones are pitted and grooved, which means it sounds like I'm grinding coffee during a ride. The wheel set is the original Matrix anodized aluminum 700c. Any advice?
