I have an old aluminum frame and I am looking to replace the rear dropouts as they are shot. I found a local welder that can do the repair. I am having trouble finding a place to buy the dropouts though. The only place I found so far is cycle-frames.com, but I am unsure of which ones to get. Can anyone help me in my search? Thanks!

Maybe if you mentioned what $&*# bike it is you're talking about...

I believe that bike is made of aluminum, so you need aluminum drop outs to start with, maybe in ceeway or nova cycles.

Dude are u sure u want to do this? Steel u can just go and weld it. I might be wrong but aluminum after being welded needs to go to an oven or probably the frame will brake just before the new welds. The new welds are stronger than the rest of the frame, that's the reason of another process, and now instead of having a frame with ugly dropouts u might end up with a broken chainstay.

What about gluing this??

Good luck...

What do mean, shot? Show us a pic of these dropouts.

That's what I was thinking too. Aluminum bike frames are usually made of 7XXX-T2 or 6XXX-T6. The T2 and T6 are heat treating processes. You're going to lose that when you weld the dropouts. I'm sure there are guys who can do it but I'd sure want to check into it before I paid somebody to ruin my frame.

Maybe you just need some of these

Regardless, fixing that frame will not be cost-effective in any way. (Unless there is some dropout protector or other thing that bolts into place that would work.) You could buy a newer, nicer bike for what it would cost to fix your old frame.

You don't mean that you need a new derailleur hanger, do you?

I really want pics.

Thanks for the help everyone.

Pictures?

Gee I thought a 2300 from that era was a carbon fiber frame with aliminum lugs glued into the seat and chain stays. Roger

It is but the rear end is aluminum so the dropouts are welded to the chainstays and seat stays.
