Regeared my 06 to a 50t rear sprocket and added an ORN6 chain yesterday. Wow that really adds some snap! I wanted to get lazier shifting and be able to leave it in 3rd all the time, for that it just needed a bit more gearing to pull out of corners. With the 50t I think it should be about perfect. Hard to believe just a few weeks ago I wanted to tame it down!
