hey guys, im sure im not the first to ask this but can someone explain leverage ratios to me? i have a good knowledge of bikes but ive never found someone to explain this to me
an average bike has a leverage ration of 3:1 which means that for ever 3 inches of rear wheel travel, 1 inch of stroke is used on the shock. The lower the ratio, the more difference the shocks damping is going to make to the feel of the travel.
then this is obviously not a constant ratio through the travel. If the leverage ration decreases (say it starts at 3:1 and finishes at 2:1 when the bike is at full travel) then the suspension is going to get harder to compress deeper into the travel, giving a progressive feel. If the leverage ratio increases, then its going to be easier to compress further into the travel giving the opposite feel
yup. Which is what the mean when the say linear, falling or rising rate. If the ratio gets higher, its a rising rate, falling if it gets lower, and linear if it maintains relatively the same.
then there's variable rate suspension systems, that are mostly falling rate, but with a more constant leverage ratio in the mid stroke, this is arguably the best performer.
