Which bottom bracket do I need?
My latest project is a Schwinn 754. I'm wanting to take the Tiagra 3x10 group (FC-4603 crank) I replaced on my Trek and put it on this bike. Currently has a square taper Suntour crank & BB. I have no idea what I need to put the Tiagra crank on the bike. Can anyone help me find an answer?
