Though they built a relatively small number of frames over a long period of time, Allin Cycles have an enviable reputation as one of the finest British frame-builders. From several different premises in Whitehorse Road, Croydon, Allin cycles traded between 1919 and 1998 having first partnered with Freddie Grubb and then later the successful racer Stan Butler. Just after the second world war Allin employed master craftsman Peter Cobb to build their custom road frames and he continued until his retirement in 1980. Stan was responsible for designing most of their high end models which were in turn named after him, the company was also heavily involved in bike polo with owner Ching Allin riding for one of the best teams in the country.

Probably one of the last frames to come out of the Allin shop and possibly built by the master builder Cliff Shrub, this neat mid 80s lugged road frame is a rarity. With a racy fast back/Italianate seat cluster, lightweight Reynolds 531 Professional tubing and chromed dropouts it is clearly built to a very high standard. The original dark metallic grey paint job and water slide decals are in good useable condition and it is ready to be built up and used.

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.

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.
