I have a older tra2 from 01 that im running on my rev. From what i have gathered, its 12 deg. Im running a 127, what i had on my zx. The 127 is a little longer and my belt deflection isnt where i would like it. I was just wondering if i was able to put a 166 or 288 on??? If it help also, i have a team roller. Thanks in advance.
