Many bottom-bracket axles will not fit unless you replace the standard 1/4" bearing balls with 15/64" or 6 mm bearing balls. The inner diameter of Raleigh cups is a bit smaller than standard.

If you are not satisfied with cottered cranks, and want to upgrade a Nottingham Raleigh frame to cotterless cranks, you will have to re-use the old cups unless you are prepared to spring for a Phil Wood bottom bracket, or a Velo Orange threadless bottom bracket - see article on cartridge bottom brackets. Fortunately, the press-fit dimensions on the head tube of the frame are the same for both. This is particularly a problem if you need to replace a fork on a Raleigh-built bike, because you will also have to replace the headset if you cannot locate a 26 TPI fork. Raleigh used its own unique 26 threads-per-inch parts, which are not interchangeable with anything else. The major areas of concern are headsets and bottom brackets.Non-Raleigh British bikes use B.S.C. Starting in the late '50's, derailers began to be used on this type of bicycle as well.Īlthough primarily intended for fast group rides with clubmates, club bicycles were also commonly used for serious touring, and also for time-trialing. Many club bicycles were single-speed machines, usually with a reversible hub: single-speed freewheel on one side, fixed-gear on the other. A very few even were equipped with the rare ASC 3-speed fixed-gear hub. The steel Dunlop Special Lightweight rims used on the better club bicycles could give the aluminum rims of the day a run for their money.Ĭlub bicycles would be likely to have a more exotic Sturmey-Archer hub, perhaps a medium- or close-ratio model, 3 or 4 speed. Even fairly high-end models used steel rims, which, at the time, were widely believed to be superior to aluminum. The poorer, less performance-oriented club members would ride sports bicycles, but the more hard-core "clubmen" would have true club machines.Ī club bicycle would typically have Reynolds 531 frame tubing, a narrow, unsprung leather saddle, reversed North Road handlebars (or drop bars), steel " rat trap" pedals with toe clips and 597 mm (26 x 1 1/4) or 630 mm (27 x 1 1/4) wheels. They were named for the fact that they were the style of bicycle popular with members of the many active cycling clubs. Lub bicycles were the elite, high-performance machines of their time and place. In addition to its role as a utility transport vehicle, the sports bicycle was also extensively used for touring and cycle-camping, on both sides of the Atlantic. Some of the more deluxe models, such as the Raleigh Superbe, would be fitted out with extra built-in accessories, such as locking front forks, Dynohub generators built into the wheel hubs, deluxe leather saddles with springs, etc. Please don't call these bikes "English Racers!" while they are very nice bicycles, they have no connection whatever with racing it is foolish and ignorant to refer to them this way. this type of bicycle was known among people who didn't know any better as an "English Racer", although they are a far cry from a racing design. The vast majority of English bicycles that made it to the United States fall into this category. These bicycles were faster and lighter than roadsters. Sports bicycles had rather more nimble frame geometry, typically with 72 degree frame angles.

They feature 590 mm (26 x 1 3/8) wheels with Endrick or Raleigh-pattern rims, full steel fenders (or "mudguards" to the British) " North Road" upright handlebars, and cable-operated brakes. Ports or "light roadster" bicycles were the basic transportation of the urban working class. customs regulations placed a higher duty on bicycles weighing more than 40 lbs.Īs of 2016, roadsters are still manufactured in India and China and are common in third-world countries. Most roadsters that were imported to the U.S. Roadsters have never been truly popular in the United States, but they are not truly rare, either. They are often pictured as the mounts of policemen and rural letter carriers. No serious attempt was made to save weight in their design or construction. Roadsters were built for durability above all else, and were intended to be able to cope with dirt roads, cobblestones and unpaved footpaths, with a bare minimum of maintenance.
