I have a (new to me) 80s AD SLE. The crown race measures 26.9 . The JIS headset races
just swim around and the European sized ones just look too small with their 26.4 size. Anyway, ideas on
how to approach this? I've read a bit suggesting that running things loose is pretty unsatisfactory.
The head tube inside diameter measures 29.9 which suggests I should be looking at JIS. Half a mm seems
a bit too much stretch to mix the two sizes.
