Alec Bird was a very well respected racer in his time who along with his Brother Ken took the oft-trodden path to becoming a framebuilder. Working out of Welling on the outskirts of London, Alec worked for Clive Stuart Cycles for many years and built some highly sought after frames.

Though branded Alec Bird this frameset is actually an Alan, built in Italy from bonded aluminium tubes and one of the lightest framesets available at the time. It's a Competizione model from the early to mid 1970s, with no cable guides or braze-ons, a real taste of the future, from the past!

If you're taking part in L'Eroica or any other 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.
