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
The final drive ratio is calculated by dividing the rear sprocket tooth count by the front sprocket tooth count. Retain the existing rear tooth count when replacing worn parts, or select a different count if you want to change the final drive ratio and have checked the chain length. Available tooth-count options are 40, 41 and 42.
Checking the rear wheel assembly
MREV also offers a Shuriken version in this range. Compare images of both designs and the carrier specifications to select the correct one. Measure the bolt-hole count, bolt circle and center bore on the actual sprocket carrier. Two sprockets with similar tooth rings may still have different mounting positions or offsets.
