I really hate trying to match square taper bottom brackets, to cranksets, to frames. It always seems like one combo of BB and crankset works great on one frame, but not another, and vice versa... It could be that I am an OCD perfectionist, but I really hate dealing with this sort of issue. I'm actually having the same issue with a Miche crankset, Miche BB, and a Leader 725 frame.

The crankset and BB work great, giving me a perfect 42mm chainline, on the Leader 725. However, the Leader 725 flexes like Silly Putty, and I end up whacking the crankarm against the chainstay whenever I skid, so I need to figure out a longer BB, thus f'ing up the chainline. Anyway, enough of my issues. Just do what I do: Buy a whole bunch of bottom brackets, have them sitting around, then you can choose and experiment with them, all day, all week, all month, all year, for the rest of your life...until you go crazy.

Or, just do what Scrod says. He's usually spot on.


I'm starting to hate my bike. Anyone want a Leader 725 frameset?
