Complete rear axle assembly, ready to install. Please choose which brake rotor version and which sprocket size you want. Earlier Main Street vehicles used a single-piston rear brake caliper and that requires the springs and spacers on the brake rotor. The current dual-piston rear brake caliper does not require springs and spacers. The 28t sprocket was standard to pedal-power-only vehicles and the 38t was used with the mid-drive electric motor equipped vehicles.
Wheel Keys, Axle Nuts, and Axle Bearings sold separately.
