Its time for me to part with this frame. I have really loved riding it, its one of the nicest steel frames I have ridden; so much so that I subsequently bought a Perthus 753 as well; and then another, and now I have three and its ridiculous.
I have ridden a few centuries on it, including Eroica (sorry) a few times, with the Tricolor kit as pictured. I guess the frame is from 1989-1990, so it seemed period-fitting. Its a nice blend of comfort and zippiness. I would say that, but this is way, way better than the Ribble 653 frames I have had.
It measures 570mm seat tube c2c and 570mm top tube c2c, 156mm head tube. It takes 25c tyres (its pictured with Conti GP Classic 25c tyres) but the clearance at the fork is tight, and a 28c won't fit at the front.
Comes with a Campag Chorus headset and a seatpin bolt.
Please don't buy it and turn it into a beater. I live in the frozen north (Hebden Bridge). You'd be welcome to collect, or else I can post.
