An important character in the South London cycling scene, Ken Bird was a master wheel-builder, team mechanic and shop owner who, along with his brother Alec, pushed the boundaries of frame manufacture. Starting with Claud Butler in the 1950s, Ken went on to manage a shop for Hinds and then Clive Stuart Cycles, he was the British team mechanic for three years until 1968, the year Tom Simpson died during the race. Though legend has it Ken and Alec were not exactly the best of friends, it is thought that Alec built some frames branded Ken Bird, with other local builders including Holdsworth and Roberts known to have built others. Ken Bird had a reputation in the 1970s for pushing how light a competitive TT machine could be, with lugs, frame tubes and components all heavily modified, drilled and lightened.
This early 1970s TT machine has all the hallmarks of a high end, lightweight TT bike as was typical of the race-winning machines Ken Bird were producing at the time. With a two digit 'BBC" frame number, drilled bottom bracket and rear dropout plus neatly brazed-on brake bolts, this was a machine built purely for performance. Fastback seat stays, a sloping fork crown and minimal lugs also indicate the high quality of this frame, and although the re-spray is not perfect, it could easily look like the top of the range bike it once was.
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.OVERVIEW

▼HELP SECTION
-
Seat Tube (ctc) - we measure from the centre of the bottom bracket shell up to the centre line of the top tube to give a consistent measurement regardless of frame design (ctc means centre to centre).
Top Tube (ctc) - this is measured from the centre of the head tube to the centre of the seat tube, along the centre of the top tube.
Chainstay Length - measured from the centre of the bottom bracket shell to the centre point of the rear dropout.
Wheelbase - measured from the centre of the front fork dropout to the centre point of the rear dropout.
Front & Rear Spacing - measured from the inside of one dropout to the other. The dropouts on steel frames can be stretched or squeezed a few mm but it's always best to avoid this if possible, aluminium or carbon frames should never be stretched.
Brake Drop - measured using wheels of the relevant size for the frame, as stated in the technical info section.
Headset Threads - although it's generally recommended to match threaded parts exactly, with headsets you can technically mix and match, unless you have French or the obscure old Raleigh threads, in which case you need to stick to that type.
