Bianchi TSX bottom bracket question
Hi,
Quick question, building up a Bianchi TSX frame, hit an issue with the bottom bracket - put in a Campag record 9 speed (rest of the group set is super record 9 speed titanium) and although it fitted fine, upon putting the cranks on the shaft is just a little too short (think its 102mm) and causes the crank to foul - any ideas which Bottom Bracket should be going in there?
Thanks, Dan.

Generally the length of the spindle is determined by the crank. Are you sure you got the correct BB for the Crankset you’re using?

Shield logo or script logo on the crank? 111 mm was the spindle length before 102 mm became the standard for double.

Is the crank fouling on the BB or the stay?
Both crank and BB are Campy so they both have the same taper. That 103mm BB should be right. Could the crankset be worn enough that its sitting too far down on the BB?
