Gear Ratios / Sprocket Changes

From the factory, the Rush SR ships with a 15T front sprocket and a 44T rear sprocket. The front sprocket is easy to change with a 32mm socket, and you can buy extra sprockets directly from RAW.

See the attached gear calculator for ratios. In short, if you are redlining in 6th, you should run a longer (higher-tooth) front sprocket. If you are not even making it into 6th, you should consider a shorter sprocket.

Our owners have also enjoyed changing sprockets to avoid "awkward" shift points. Sometimes it is better to redline 6th for a moment and enjoy shorter ratios on the rest of the track!
