threaded steer tube replacement on vintage bianchi
well, something terrible happened.
my new (to me) 1983 Bianchi Super Leggera Specialissima was assaulted.
i was at the local bike shop, getting the headsets switched out on my new and old Bianchis, when the person working on my bike made a grievous error. Said person was not being careful with a certain tool, and preceeded to cave in the top of my steer tube. After much panic, the lead mechanic cut the top of the steer tube and was able to get the top of the headset thread on what was left of the steer tube.
After everything was said and done, there was probably 3mm cut off of the top. Since there was so little material available to cut in order to get the headset to thread back on, they couldn't remove the entire caved in portion. That being said, the threads at the top of the tube are flared out and up, and the once clean and factory perfect fork is now hacked. Yes, the headset tightened back up, but I don't know how confident I am in this "repair".
am I over reacting? is there nothing wrong here? the bike is full columbus tubing, and that raises the question: if I decide to have the steer tube replaced ($125 at Joe Bell and Cyclart here in town), is the steer tube made out of columbus SL tubing or just the fork blades?
