I just receive my Colnago Sprint and found out that I can't ride it because the chainring touch the frame. When open, I see that the spindle is 68-ss when my BB is 70mm. Is it the reason the chainring touch the frame? I would say 2mm different only cause the left side cup to go deeper inside instead.
Anyone have experience with this problem? I worry that the crank hole get loose and cause the crank to go deeper as the bolt is tighten.
Your help is appreciated.
