Founded in the latter part of the 19th Century, Carlton managed almost 100 years of bicycle manufacturing in the East Midlands. They were amongst the most sought after and readily available British bikes of the 1930s, thanks to some nifty salesmanship from Dan O'Donovan who was to later take over the company, and whose son Gerald became a frame designing legend. Following a buy-out by Raleigh in 1960 and a rebrand for the US market to 'Raleigh-Carlton' the company grew and grew through the bike boom with the doors finally shutting at their Worksop factory in 1981.

This late 1940s or very early 1950s Massed Start is a wonderful post-war all-rounder. Like all Carltons at the time, the Massed Start was mass-produced, but still to some extent customisable by the buyer, with colour, braze-on and lug style options. Featuring distinctively shaped lugs, mudguard braze-ons and fine attention to detail this will build into a wonderful ervey day vintage bike.

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.
