I had a quick question for you...
I picked up a frame on eBay a while back. I failed to notice that it was disc only. I was going to get rid of the frame, but then I thought about adding the bosses. I know it is tough to weld on aluminum, but not impossible. Has anyone had this done, and if so, how much should I expect to pay?
Thanks!
Robert

Welding Al isn't that hard - with lots of practice ;) There is no colour change on heating and if you havn't done it before there is a good chance you will melt the frame.

After welding the frame will have to be reheat treated, or failure could happen quite quickly.
Success is how far you you bounce back up after being knocked down

Ok. It sounds possible, but not easy. I think I'll pass. :(
If anyone is interested in a disc only 19"/M 2001 Giant XTC SE1 send me a PM.
Thanks for all of the info, guys!
