New toptube needed.
Hop we can get some help for a problem w a damaged toptube. The tube is not damaged from a crash, so the rest of the frame is fine, and since the frame is the biggest we could find around here (62 cm) we hope it is possible to replace the toptube.
It is a low end 1980`s Gitane, lugged. I`ve got a similar Mixte that I really like, so we hope to repair this bike.
We are both new to this (but not to metalwork like welding and brazing) and need to ask:
I hope remowing the old tube is just about to cut it twice (take out a part in the middle) and then heat one side at the time to get the pieces out.
I am more worryed about fitting the new toptube. Can we just carefully bend the frame and put the new toptube in?
I guess silver brazing is the way to go.
And first of all: Buying the new toptube is a challenge, no framebuilders around here. Found this online: http://www.metals4u.co.uk/products.a...FdsU3god5S55Lw
Can I hope to buy something from them suited for our repair?
Wery happy if somebody can help!
