I have an '85 SL framed bike with fully chromed rear triangle. Measures 58X57 (ctc) with a 16cm head tube.
Mine has practically zero decals. It's a proof of authenticity for
il cognoscenti.
If you find a source for replacements forks , PM me, the Tange on mine must be a track-like fork = very twitchy. But the bike tracks well no-hands with no counter-balance input.
As purchased, still a project without clear direction.
