Rim – alloy (WM3X18)

Alloy WM3x18 rear wheel rim, listed in the 1973 catalog.

PN · 37-3940

This is an alloy rim, WM3 profile, 18 inch, listed against the rear wheel figure in the 1973 catalog. It's the hoop that the spokes pull up to and the tire seats on, laced to the rear hub with the usual spoke pattern for the wheel it belongs to.

The catalog only shows this one appearance for 1973, so we don't have a wider spread of years to point to. If you're rebuilding a rear wheel and need to confirm this is the right rim for your hub and spoke set, give us the specifics before you order.

We don't have more detail on this one beyond the rim size and profile. Call the shop and we'll help confirm fitment against your actual wheel.
