My original FSA Alphadrive is getting a little creaky and old. It is a year old and I'm looking to replace it with something new. Definetely want to upgrade to a newer style external bearing type crankset. Looking to spend less than $150...

One thing that I am wondering also is I am looking to gain a few mm's for a blackspire blackguard inner bash ring that bolts to the granny ring to clear the chainstay. my previous setup was a 68mm shell with a 113mm bottom bracket. the inner guard rubbed on the chainstay before I even had it tightened down all of the way, so I may need 3-4mm of additional clearance.

Just wondering some good recommendations that will fit my 07 Komodo.
