BB size for a porter??

[burgerks]

I think my BB is too short with my chainguide. My left crank keeps coming loose, I'm running an e13 with a 9 speed any suggestions?
thanks!

oh yeah, I'm running Truvativ Hussfelts and a howitzer. not sure on the size though. I'll check it tomorrow.

The BB is 73mm shell and 140mm spindle....I'm at a loss for trying to find a BB that will work...

Your crank coming loose has nothing to do with the right or wrong BB size. Is it your crank coming loose, or your bottom bracket?

Try a couple drops of blue loctite on whatever thread is coming loose.
