1980ish fast tourer built for closer clearance 27" but with 700's .....
Not an easy find frame wise but worth the wait , nippy but stable
I've got a Raleigh xc80 too that is upsettingly light and responsive but stable enough on the lumpy stuff . Both will take 43 c tyres .
I've got round this in the past by using a spacer between the fixed cup and the bb shell . 3mm makes it much better . I'm assuming it's due to Italian bb's being a 70mm shell not 68mm .
