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
If you are replacing a worn sprocket and are happy with how the bike rides, retain the existing rear tooth count. With the front sprocket unchanged, adding rear teeth increases the final drive ratio. The chain may need adjustment or a different length. Available tooth-count options are 36, 37 and 38.
Checking the rear wheel assembly
Do not transfer tooth-count selections from Leoncino 500 or TRK502 to TNT 125. 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.
