What does an Ultralumin 7000 aluminum sprocket offer?
The sprocket body is CNC-machined from Ultralumin 7000 aluminum alloy. Aluminum allows the center section to be shaped and has a lower mass than steel for the same material volume. The anodized surface adds color and helps resist corrosion. When selecting a new sprocket, check the tooth count and sprocket carrier. To compare it with a steel sprocket, use two sprockets of the same dimensions to establish the actual weight difference.
Selecting tooth count and chain size
A different tooth count can change the bike's response. With the front sprocket unchanged, fewer rear teeth produce a lower final drive ratio. To retain familiar riding characteristics, keep the existing rear tooth count. Available tooth-count options are 41, 42 and 43.
Checking the rear wheel assembly
Compare the bolt-hole positions on the RS250 carrier before selecting a tooth-count option. If the rear wheel has been changed, use dimensions from the carrier currently fitted rather than an image of a sprocket on a bike with stock wheels. Check that the chain runs centrally on the tooth ring.
