Also: what year and size Black Lightning?

I was looking at catalogs recently, and the fork rake on the Criterium series frames varied by size.

Less rake than many road forks. Looking at the '88 catalogs, 1.5" rake on most frame sizes...so 38mm rake/offset? That's limiting your options right there.

Carbon wouldn't look out of place, IMHO. Maybe a 40mm Ouzo Pro or Kestrel? Used, and even sometimes NOS, can be had at reasonable prices...

For steel options, Soma has a Tange Prestige Track fork ($180) and a Pake Unicrown Track fork ($100) w/38mm rake. Both avail in 1", but threadless only. Must be threaded equivalents out there if desired...

You may have other ideas, no doubt.
