    Your Sugino GM should fit the same BB as a regular Sug 75. I got mine on a Miche, though it's a cheap BB for a non-cheap crank.

  • Sugino do a 103mm BB, which I needed to get mine running right.

  • I'm using Miche Primato BB with the 107mm axle.

  • The Grand Mighty uses a 109mm spindle length.
