Well I finished my project of changing my 151 Summit to a 162. I used a 162x16x2.3 Maverick track. Avid 7 tooth 3 inch pitch drivers. 159 rails set back 1 inch. 159 tunnel extension. Anyone running something like this? Where did you end up as far as clutching and gearing? I get to ride later this week so I can't wait to see how it does.
