I thought that the spragg clutch was different to the "norm" in that it made the gear change smoother due to the instant pick up of the fly wheel...it is actually used on Gym equipment at our school and Nelly showed me a new one ages ago...(could be wrong though and the terminology is probably completely incorrect AND I'm sure someone will be along to put me straight ...After all I have a head like a sieve and I am a woman!)
