Historically the universal go-to material choice in bike frame building for over a hundred years. Steel is relatively inexpensive and offers high strength, long term durability, and can be repaired with relative ease. However, as most people are aware steel is very heavy, plus it can rust and corrode if not properly cared for. Fun Fact: Although quite heavy a growing niche of cyclists prefer the ride characteristics, simplicity, and solid reliability of a durable fully rigid steel framed bike on plus sized tires, often seen in all-terrain bikepacking rigs.

The combination of aired-down large volume tires and steel frame make for a surprisingly smooth ride. While significantly lighter than steel, aluminum is a dependable lightweight metal option with benefits that also include strength, corrosion resistance and being rust proof. Fun Fact: Depending on material grade some high-end aluminum frames beat out low grade carbon bikes in both lightness and strength.

What makes titanium such a wonder metal is its combination of steel-like strength and lightness like aluminum. For example, aluminum, which is actually significantly less dense than titanium requires a significantly thicker frame wall than would be required of titanium to provide matching strength. Having to spec a thicker frame offsets the weight advantage aluminum would normally have versus a titanium frame of the same design. Fun Fact: The strength to weight ratio and natural anti-corrosive properties of titanium make it an ideal material for use in harsh environments — aircraft, naval ships, spacecraft, armor plating, missiles, ship propellers, oceanic equipment components, submarines, radioactive nuclear waste storage, surgical implants and medical instruments — just to name a few.


Even original owners have a hard time remembering the year that they purchased the bicycle. That said, it is possible to date a bike within a couple of years with some confidence based on frame features and components. Older bicycles have a serial number on the underside of the bottom bracket.

Modern Cannondale bikes feature the bicycle’s serial number on the bikes may have serial numbers placed on other areas of the frame.

If you are reading this for anything other than SB number sequences from the SBDU then please make sure you corroborate my information with other resources. Although the explosion of social media has meant that there are numerous Facebook groups and internet forums where information is given, I frequently see this quite simple topic explained or interpreted incorrectly over and over again. There are several sources for Worksop frame number information, but with every piece of information on the internet, the very first things you should ask yourself is… where does this information come from..?

Who wrote it..? What is their experience and background..? However, as time goes by and more information is seen, a fact with unknown provenance can become an accepted piece of data if it proves time and time again to be accurate. The start date, although not proven with any documentation as far as I am aware, seems to be an accurate piece of data, and because of this, it is becoming the accepted date.

There is only a single number from 0 to 9 to represent the year, therefore a single number will be repeated every 10 years. To decide between the decades, you need to know a little about s and s bike design. In my mind there are lots of differences between a s bike and a bike from the s — a bike will look very different to a bike.

Engine & Frame Numbers

Sometimes local bike shops etched serial numbers into the rear dropout, but this number may or may not match the original. If your serial number and component dates match, you are probably in good shape. If not, the bicycle is no older than the latest component, but you will have to estimate the age e.

But the E also appears for frames in the early 80’s. So use the list wisely. If you have over-bottom-bracket cable routing, you don’t have a ‘s frame. Some bikes.

Classic Lightweights UK Restoration. In these cases examination of the frame number — where it is, what it is, and how it is, may be of some assistance at least in allowing other specialists to hazard a guess at the true origin of the frame or machine. These publications have been invaluable in adding accuracy to the information — but even including their data there are still well over makes of possible lightweights to be confused over!

The author would be grateful to know of any inaccuracies and to receive further information to make the tables more comprehensive. For example, some BSA frames have BSA and a 3 or 4 figure number cast into the base of the BB, this is just the casting number or perhaps a model number — it is not the frame number. Nervex, the lug maker, also had their name on their BB lugs with a long design serial number.

Make a note of where on the BB the number is and its orientation — for example, is it upright or inverted for reading when lifting the front wheel up with the rear wheel still on the ground?

However, there are a few BMX restorers who have painstakingly attempted to decipher these multi-digit mysteries. A big part of buying, rebuilding and restoring old BMX bikes, is knowing exactly how old they are. It seemed nobody figured out how to read the serial numbers. Generally the year and month of build was stamped as the first part of the serial number.

Below is a list of serial numbers and descriptions for a variety of Eddy Merckx steel frames. When looking at the bottom bracket, with the frame veritcal and the headtube at the top, read this as upper left, lower left, lower right, upper right. Sort of a U shape. Because it sets a standard way for me to record this info, no other reason.

Only when either a frame has been date verified by Gitabike or the Merckx factory do I add a verified model year. Model year bikes are begun production the year before, and as such its possible for their date code to be somewhat different than what the pattern suggests. The left side of the serial gives model and sometimes size information. Sometimes there are some other letters I haven’t deciphered. But here’s the general gist.

What this chart is intended to be: This chart has been developed as an additional reference guide more so then simply dating off Sturmey-Archer hubs for the positive identification of Raleigh frames and entire bicycles. As proper factory documentation is very limited, the following charts are a constant work in progress; they have been compiled by examining numerous Raleigh frames from each period, component date codes, decal schemes, color availabilities per year; and – occasionally – official papers.

That said, these charts are representative of U. There isn’t enough data to claim either option as absolute. Keep in mind that these charts are incomplete, and there is a reasonably wide margin of error between serial cutoff dates. Nevertheless, please put your mind at ease – these serial charts have been checked, re-checked, and are as accurate as I can provide at their time of publication.

If new information is found, these charts will be duly updated to reflect such. Otherwise, you might accidentally misidentify your Raleigh bicycle.
