The Joco company was started by Matheus Antionius ('Toon') de Jonge in 1919 and began building frames five years later from their base in Amsterdam, quickly becoming highly regarded throughout Europe. Offering four models: the Course; Super Course; Tour of the Netherlands and Tour of Europe in road and track versions, their bikes standing out from a sea of identikit black bikes by the judicious use of brightly coloured enamal finishes. Though Joco haven't built any frames for fifty years their reputation as a high-end builder is still intact and they are still much sought after.

This wondeful Ronde Van Europa (Tour of Europe) model track frameset from Joco is built to an impeccable standard from Reynolds 531 tubing and Nervex 45/159 lugs. With a stunning enamel finish, neat lug lining and chromed rear triangle, forks and head tube lugs this was clearly a very high end frame. A rare opportunity to pick up an unrestored period race machine from one of the best builders of the time.

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.

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.
