These lovely quality 'Donna' dropped top tube race frames have never been finished or built up, and are available here in their raw state ready for painting. With their internal cable routing, fine lug-work and neat finishing they were obviously built by a talented frame shop, although we are unsure exactly who this was. The frames also feature downtube shifter bosses, a braze on front mech mount, neat dynamo light cable guides, mudguard eyelets and a pump peg. Chromed on the rear dropouts and drive side chainstay, and with a chromed fork they will look fantastic with a single colour or more adventurous paint job.
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!

▼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).
(Effective) Top Tube (ctc) - this is measured from the centre of the head tube to the centre of the seat tube, along the line where a top tube would be to give you an indication of length.
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.
