SPROCKET 45T
A 45-tooth rear sprocket, part number 37-7089/45.
This is a 45-tooth rear sprocket, listed in our records under part number 37-7089/45. The catalog note we have is brief, and the manufacturer tag on file doesn't line up with what a sprocket actually is, so take that tag with a grain of salt.

A rear sprocket like this bolts to the wheel and takes the drive from the final chain, working with the gearbox sprocket to set the final gearing. Tooth count changes on a rear sprocket are one of the more common ways owners tweak how a bike pulls versus how fast it spins at speed.
We don't have more detail on this one beyond the tooth count and the part number itself. Call the shop and we'll confirm fitment before you order.
