I’m going to have to check the fork crown on my ‘81 412 now...
@
bikemig, did your 500 come with 27” wheels? My ‘78 and ‘81 both came with 27” wheels, which made for great 700c conversions.
Agree that the Ishiwata 500 series are fantastic bikes and often great deals.
I think my ‘79 710 looks great with a Sugino AT crank - you should go for it! (See sig in desktop mode.)
