Continuing the recent Miyata theme, I just finished retromodding this '87 312 Competition into a gravel grinder.
I’ve done a similar mod with my ‘84 710. Cold-set the dropouts for 1x11 11-40 with 42T chainring. 28c Panaracer GravelKings. Went with flat bars, so more hybrid-ish for me. I’ll attach an image the next time I clean it up.
