Sturmey-Archer derailleur main image

Another no-messing Shimano Tourney copy - with exactly nothing interesting about it - except the venerable brand.

Who exactly was Paul Spring (HSA120) and where is he now? Almost certainly lost in space on the planet Pinion (HSA115) etc. etc.. If you understand these two sentences you have spent too long working in bicycle shops and there is little hope of a full recovery. You should probably also go easy on those funny-smelling, extra-long cigarettes!
