What does an Ultralumin 7000 aluminum sprocket offer?
The sprocket is machined from Ultralumin 7000 aluminum and anodized. Aluminum weighs less than steel at the same volume, making it an option for riders seeking a lightweight rear sprocket material. Anodizing adds color and helps protect the aluminum surface. The teeth still require the correct chain size and wear inspection during maintenance. The complete sprocket's weight also depends on thickness, tooth count and center cutouts.
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 37, 38 and 39.
Checking the rear wheel assembly
If changing the rear tooth count, check chain slack after installation. 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.
