Bryan M · 01-12-2008, 03:49 AM

I installed a 25 sprocket to a 14 freewheel.
But now all i do is accelerate to like 13 MPH
Im going to spend another $80 on a new cassete with 9T.

Which should i go with, buying new gears which are 25/9
or reverting to 39/14.

Can you guys please tell me the FASTEST ratio?
Thanks
