I just purchased the GiPro ATRE and speedohealer. I am going to be replacing my sprockets with AFAM along with a DID 520ERV3 chain. Just wondering what you guys think: with the addition of the ATRE is there a need for a +2 rear sprocket? Basically what I am asking is will the +2 make the bike difficult to handle when used with the ATRE? I am definitely going -1 with the front sprocket.
