Rear Sprocket 44T

The 44T rear sprocket is the factory default rear sprocket on the Rush SR, paired with the 15-tooth front sprocket as the standard final drive ratio. This is the OEM replacement for the stock setup — not a gearing change.

The Rush SR uses a 530-pitch chain drive system. Only the RK GXW 530 chain is recommended. The rear sprocket is fixed for spec competition — the 44T is the only legal rear sprocket. Gearing adjustments are made at the front: the 14T and 15T front sprockets are the two legal configurations, swappable with a 32mm socket.

If you're replacing a worn sprocket and staying with the stock gearing, this is the correct part. Sprockets should be inspected regularly alongside the chain and replaced as a set when worn.
