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 45, 46 and 47.
Checking the rear wheel assembly
Record the existing rear tooth count to distinguish a direct replacement from a gearing change. The sprocket-to-carrier mounting arrangement may differ even under the same bike model name. Photograph the bolt heads, contact face and center bore to avoid selecting a part that only looks similar externally.
