This from the 1990 catalogue. Triple in Xenon and Athena only, not Chorus, Croce d’Aune or Record. 170mm crank length only by the looks of it. Hope that helps.
Maybe a little leftfield but I’ve got a nice set of Syncros Lil’ Snapper rims on Real hubs with multi-coloured anodised nipples. In excellent order except one of the rims has faded a bit from the original black.
Is it steel? If so I’ve got the exact thing for you. 165mm, taper and threads all good. Yours for a donation to Cancer Research. PM me your address if you want it.
