CHROME RIM, REAR 18in TRIUMPH SPOOL 650 1963-70, 500 1963-74
Chrome 18 inch WM3 rear rim for Triumph spool-hub and QD-hub wheels, covering 650 twins through 1970 and 500 twins through 1974.
This is the rear rim for a Triumph spool-hub wheel, an 18 inch chrome rim built to WM3 profile with 40 spoke holes. The catalog lists it against the 650 twins through 1970 and the 500 twins through 1974, and it shows up across several rear wheel and quickly-detachable rear wheel figures in the parts books, so this rim covers both the fixed spool hub and the QD hub setups depending on which one your bike carries.

The old-book alias W1007 is the same physical rim under Triumph's earlier numbering, so if you're working from an older parts list and see that number, it's this part. Given how many figure titles this rim turns up under, it's worth double-checking your hub type and spoke pattern against your own parts book before ordering, since spool and QD hubs on the same model years don't always share the identical rim spec.
A chrome rim like this one is a straightforward swap for anyone rebuilding a wheel from scratch or replacing a rim that's pitted or out of true, and it gets you back to the correct WM3-18 dimension for the stock tire and brake setup on these bikes.
