Rear Sprocket for Dat Bike Quantum
MREV-P-000032Quantum rear sprocket: CNC-machined Ultralumin 7000 aluminum for riders considering rear sprocket weight. Select the correct sprocket carrier and chain size. The anodized finish adds color and helps protect the surface.
The Quantum rear sprocket is the large sprocket fitted to the rear wheel of Dat Bike Quantum. The product image shows a gold aluminum sprocket body, large cutouts and four mounting points in the center.
7000 aluminum and the cutout center
The sprocket uses Ultralumin 7000 aluminum. Aluminum is selected to control rear-wheel component weight. The center cutouts are part of the design and create a recognizable appearance. The teeth still carry chain loads, so chain care and correct chainline matter for wear. Riding range cannot be calculated from sprocket material alone.
Selecting tooth count for the intended use
The sprocket is available from 49 to 53 teeth for a size 428 chain. With the front sprocket unchanged, adding rear teeth increases the ratio. Retaining the existing tooth count is a starting point when replacing only a worn rear sprocket. Compare the actual carrier, four mounting points, tooth count and chain markings before installation. The 13-tooth Quantum front sprocket is a separate part from this rear sprocket.
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.
