Rear Sprocket for Dat Bike Quantum Double Plates Dart
MREV-P-000029Quantum Double Plates Dart: Ultralumin 7000 aluminum with a two-layer center design, considering weight while giving the rear wheel a distinct appearance. Select the tooth count to suit the front sprocket and chain currently fitted.
Quantum Double Plates Dart is a rear sprocket for Dat Bike Quantum with a Dart two-layer center design. This model suits riders replacing an old sprocket who prefer the Dart design on the wheel assembly.
Aluminum material and the two-layer center
The sprocket is CNC-machined from Ultralumin 7000 aluminum. Aluminum has a lower density than steel, so an aluminum sprocket aims for lower weight when compared at the same dimensions. The two-layer center changes the appearance. It does not itself increase an electric bike's power. Select Dart using images of the exact product, as the Quantum Double Plates range also has a version without this pattern.
Fitment and tooth-count selection
The sprocket is available with 52 teeth for a size 428 chain. If your Quantum uses a 13/52 combination and you want to retain its gearing, compare the 13-tooth front and 52-tooth rear sprockets before replacement. The new sprocket must also match the carrier bolt circle and chainline. Changing tooth count may affect chain length and wheel-adjuster position.
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.
