Britain's rise to an industrial superpower on the crest of the Industrial Revolution was based, as much as anything else, on the steel industry and the new technologies it made possible: steel ships, steel bridges, steel buildings..steel bicycles.

Raleigh originally introduced the slogan "The All Steel Bicycle" to differentiate Raleighs from competitors who used cast iron for some critical parts, a heavier and cruder technology.

A Raleigh bicycle of this era would have a Raleigh frame, made of Raleigh Tubing conected with Raleigh lugs, with a Raleigh bottom bracket, Raleigh cranks, Raleigh pedals, Raleigh headset, Raleigh handlebars, Raleigh stem, Raleigh seatpost, Raleigh hubs (Sturmey-Archer was a Raleigh subsidiary) and even Raleigh spokes.

All of these parts would have been made in the same factory.

The men and women who built them, by and large, also rode them, as their primary means of transportation.

Most modern bicycles are designed with the primary intent to catch your eye on the sales floor, and persuade you to buy.

Note that the serial number information below is fragmentary and incomplete, and many bikes have proven to be much newer than the serial numbers would suggest.

usually shared similar technology, though these models tended to have mattress saddles, Endrick rims, no chainguard braze-ons, fender stays bolted (not welded) to the fenders, and anchor-bolt type brake cables. The handlebar, cranks, brake levers, fork crown and cable hardware were painted black, not chrome plated (chromium was a strategic material, not available for civilian use.) Stem and brake calipers were chromed. The lamp bracket attaches to the handlebar binder bolt, rather than to the headset. Seat tube, vertical: RALEIGH The All-Steel Bicycle. Frame features "Pletscher"-type plate bridges, but otherwise is a dead ringer for Nottingham production, including 2030 label. Older Raleigh-made brakes used special cables with moulded ends on both ends of the cables, as shown. They were supplied in different configurations for front, gent's rear and lady's rear applications. To replace the cable assembly, you would unbolt the adjusting barrel from the caliper.

Top tube: Made in England (italic script) Down Tube: no markings. These cables can often be revived by dripping oil into them and working them back and forth. ) to reduce weight, but the braze-on was continued until (?

In general, the quality reached its peak in the 1950s, and quality started to go down around the early 1960's, as management kept searching for ways to make the bicycles cheaper.

This table is focussed on the mainline Raleigh/Rudge/Humber "Sports" model.The tables below are being compiled by examining bicycles that come in for service, and appear to be in original condition.
