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.
Checking the rear wheel assembly
For off-road use and repeated sprocket replacements, monitor chain and front sprocket condition when changing rear tooth count. Remove the old rear sprocket to inspect its markings and back face, then compare the mounting dimensions. Compare the bolt circle, center bore, thickness and chainline.
Recorded gearing options
Only recorded pitch, position and tooth options are shown. Final-drive changes must be evaluated against the complete front/rear setup; tooth count alone is not treated as a performance claim.
