WS6 A33 is an alloy wheelset built to match most Moulton bikes but it will be also compatible with other bike brand models sharing key specifications like rim diameter (406 mm) and hub OLD (100/135 mm).
| P/N | Hub | Rim | Rim W/H/D (mm) | Weight (g) |
| WS6 A33 | HR3 | Alloy | 22/33/406 | 1260 |
This version of the HR3 hub has a wider rear spacing (135 vs. 130 mm of the road version of the hub). What does not change is the G72 ACCELERATION freehub system with 6 pawls working in groups of 3 to offer 72 engaging points. It delivers smooth and fast transitions while producing a nice and quality sound.
