The replaceable drive-side rear dropout for VelectriX's belt-drive bikes: the Cruiser Pulse STX, Brunswick and Newtown. VelectriX also calls it the belt drive derailleur hanger.

  • Drive side only – the side the belt runs on.
  • Pairs with VXAUS10512 – the matching non-drive-side dropout, if both sides need replacing.
  • Replaceable by design – a damaged dropout gets swapped, not the frame.
  • Genuine VelectriX part – part code VXAUS10043.

Why it matters on a belt drive

The rear wheel sits in the dropouts, so a bent or damaged one affects how the wheel and belt line up. Getting it right keeps the drive running smoothly.

Fit and compatibility

Suits the VelectriX Cruiser Pulse STX, Brunswick and Newtown, drive side only. For the other side, order VXAUS10512. Compare the shape with the photo, or ask Tune.

Tune can fit the dropout and set the belt up correctly.
