An even bigger problem looms on the horizon, or has
already arrived according to SJS at

700c - 622 The most common larger wheel size now,
superceded the 27" (630) size"

When was the last new bike with 630 rims produced - 1975? 1985?
SJScylces still offer two rims of that size, so where's the
problem?

The Kingcycle Recumbent was sold in the mid-1990's with 390
front and 541 rear wheel. The 390 front wheel can be
replaced by a modern 406 fork and wheel no problem but for
541 there's no possibility of a replacement at all...






Japanese domestic market had major brand 630mm bikes within
the last 5 years. Haven't looked lately.
