Think the cost of getting a new headtube and bb shell welded in would be more than the bike cost new! Plus the cost of a new coat of the wishy-washy lilac and yellow paint job.
Have thought about it though, maybe I'll save up...
I need to change the pedals, build up a triple chainset, fit grips when they arrive, source M700 front and rear mechs. Other than that it's just about finished. Rides a treat.
