I ride an SA equipped bike in the winter with an extra low gearing set up and have a Raleigh Twenty folder and a 1954 Raleigh Sports Club bike I ride in the summer.

The Twenty is geared down for lower speeds and more utilitarian riding and the lighter weight Sports runs taller gearing as it rarely carries as much and likes to go faster. It has a 48 tooth chainwheel which was stock during this era.





I also have a 1951 Raleigh Sports with stock gearing and it too has a 48 tooth chainwheel but runs on smaller tyres than the 1954 so has slightly lower gearings.
