Building up a Pake c'mute, and i'm trying to install a Sram S300 Crankset (thanks for sending it out so fast Scrod). The problem i'm running into is the Chainring is rubbing on Frame. Never had this problem with this crankset. on other installs. Fram is a 68mm BB shell.

I know not to put any spacers on a GXP BB.

Any Ideas?

Smaller Chainring? 46T?
Can i move the Chainring to the outside of the spindle?
