RIM,REAR BSA WM3X18 QD
Rear wheel rim, WM3 x 18 inch, 40-spoke, for BSA quick-detach (QD) rear hubs.
This is the rear wheel rim listed in the books as WM3 x 18 inch, built for the quick-detach (QD) rear hub setup shared across BSA models of this era. It's a 40-spoke rim, sized to the crinkle-hub QD rear wheel arrangement rather than a standard bolt-up hub, so check what hub you're running before ordering.

The part number 42-6371 shows up in our records as an earlier catalog number for this same rim, with the number 37-2291 (also seen written CW37-2291) as the later factory designation. If your parts book or an old wheel still carries the 42-6371 stamp, this is the same physical rim you're after under the current number.
We don't have more detail on this one beyond the rim size and hub type, so if you're unsure whether your hub is the QD crinkle style, give us a call before you order and we'll help confirm fitment.
