'82 Trek 710 Frame Repair
Greetings. I hope this is the right forum for this post - I am looking for educated opinions...
I was changing the rear wheel on my older Trek when "pop" the cross tube that holds the rear brake pulled free from one of the seat stays. Looking at the joint is it rusted except for one tiny 1/8" spot so this has been just waiting to let go for a while.
Several years ago the rear end was damaged and the seat stay had to be bent back into shape. I assume this put pressure on this joint or cracked the weld then and it has just now given up.
My question is - how should this best be repaired and what would a reasonable cost be? Can a competent welder do it or do I need to find someone who knows bicycle frames?
Can the two parts be pulled together and welded or will this result in stress on the frame because they are being pulled in - in other words does the seat stay need to be rebent/reshaped?
I do not know of any frame builders in my area (eastern NC - anyone out there?) but will ask at the local bike shop this weekend.
I am a bit desperate because I have been riding 100+ miles a week and this is my only road bike. In fact I think I am going into withdrawal already.
Thanks for the advice,
well...good news, bad news
The good news is that I found a place in town that sells the brazing silver on Monday and managed to do a half way decent job repairing the frame. Shot it with a quickie paint job and put it all back together so I could make the group ride tuesday evening.
The bad news is now the chain is jumping on the rear cassette every time I pedal hard in the smaller cogs. I replaced the chain, swapped rear cassettes, adjusted the (friction shift) cables, but nothing works.
I cannot figure how I changed anything with the frame that would cause this but I don't know...anyone have a clue....
blocked the drops and massaged it back into shape with a rubber mallet
oops should have sanded more paint off
quickie paint job until I get another bike and can repaint this whole frame
