• In recent weeks, I've started to totally get into a system where you use the differential between the changing ring and the sprogett - as long as you wrap the same chain around them - to create a gearing effect which you 'feel' through the crangs, but is actually acting upon the wheel which is behind you strangely enough.

    What this has resulted in, is a definite ability to go along, and you can vary how you go along through foot movements by at least 5% either way.

    I'll never go back to a deraylieur, even with the purity of frictionless crossbar levers.
