| To get a rough idea of ratio is easy on any bike Find out how much rear wheel trave it has, usually stated in the specs and then look at the stroke of the shock.
If there is about 120mm of rear wheel travel and 60mm of stroke on the shock then the ratio is around 2 to 1
Ali your original schoolboy method would give a shock stroke of 240mm, would certainly make for a very long shock well over half a meter long |
