Home News Sport Business. Johnson made of the machines in with only 12 known to be in existence today. Bear in mind that owners often updated their bicycles over the years; though we might like our bike to match its catalogue description, updated parts are also a valid part of its history and provenance. Details of the following manufacturers have been published, so I hope this page can provide an easy reference point.

The Raleigh Heron Head transfer was introduced in In the same year, mudguards received a forward extension. The company had been taking steps to make it harder for makers of cheap bicycles to copy Raleigh parts. The following dated bicycle frame numbers from the Singer Car Club not guaranteed:. I started to collate frame numbers from s Triumph bicycles, and will update it as I go along. You can see it at the new Triumph Bicycle Museum. This data is approximate. For example, , might be or The best bet on post machines is to check the Torpedo rear wheel hubs.

Since around they used a production stamp, with which they can be dated:. The cycle industry was an early adopter of the new chrome process, and chrome was first used on bicycles in Maurice Selbach is believed to have been the first British manufacturer to have used it in see extract from his catalogue, below.

Catalogues were generally printed the year before the season indicated in a catalogue. By it had become widely used. If you want to date a vintage bicycle and it has chrome parts, it is generally accepted that it would have been made from onwards, or updated if made earlier. The Arai drum brake is used during long downhill descents where a rim brake might overheat the tire and possibly cause it to fail. The drum of the brake screws onto the left side of the tandem hub, which must be threaded for the drum.

The shoe plate slips over the axle and a small reaction arm from the shoe plate engages with the bicycle frame to prevent the plate from turning. The brake is designed to be engaged continuously during a descent to maintain a steady speed. The standard brakes can be used in addition as necessary. Some modern tandems use disc brakes , with all the advantages and disadvantages that entails.

Determining the Age of a Raleigh

The rear rider starts clipped in while the front rider holds the tandem upright. For those who can get accustomed to the rear rider always being clipped in, the distinct advantage to this technique will become obvious when trying to start at the foot of a bridge or on a hill.

If the tandem team does not practice this, then they often reserve this type of start for when they are faced with a bridge or hill. This technique allows the rear rider to apply continuous power as the front rider steadies the tandem during the initial take-off. This reduces the risk of the tandem toppling over due to starting on an incline. The rear rider will continue to pedal as the front rider attempts to get the foot used for steadying the tandem clipped into the pedal. In in-phase pedalling, each rider's cranks are the same or opposite clock positions at any point in time.

In out-of-phase pedalling, both riders have their cranks in differing non-opposite positions.

This has the potential for a wide range of variation. Generally, OOP provides the greatest benefits to the tandem team that has disparate leg-strength. Using OOP makes a significant difference in gearing choice as each rider has the full mass of the tandem in their power stroke, so lower gears are preferred. However, using OOP can help develop leg strength for the very same reason.

Some argue that this produces a smoother power stroke, or that it reduces stress on the drive train because the point of maximum power is reduced to roughly half and distributed over the chainrings. Since the market for tandem bicycles is significantly smaller than the market for single bikes, there are far fewer tandem bicycle manufacturers than single-bicycle manufacturers.

There are a few builders who specialize in tandems, as well as single-bike makers who offer tandem models. Current notable tandem bicycle manufacturers include:. From Wikipedia, the free encyclopedia. For the song, see Daisy Bell.
