Most of us just put up with the jibes - we need those gears!

The ones with shorter cages generally have the angle of the parallelogram set at a shallower angle. This means that the top jockey wheel doesn't move downwards so fast as it moves inwards and remains closer to the sprockets.jethro10 said:Ok, that makes sense. So.....why not use a long one all the time, just in-case you feel like changing rear gearing.
What would be the advantage of a shorter one then?
