This nicely made lightweight road frame came to us with the remnants of Roberts decals on it, we're not convinced it is a Roberts, however we are convinced it'd make a great winter bike or commuter. With minimal lugs, a low weight and a 27.2 mm seat post size it's obviously a top-end frame, and the mudguard eyelets and decent tyre clearance make it a practical choice for a speedy commuter build too!
If you're taking part in L'Eroica or a similar vintage event, this frame is of the correct age, so you won't be disqualified for being a rule breaker!
The frame's been carefully checked by one of our mechanics to confirm the alignment's correct and there's no damage to the threads. If there are any minor issues worth noting we will do so in the overview section below. Please take a good look at the detailed photos so you can see the cosmetic condition of the frame before you buy.
