What does spring rate mean? And which should be selected for that?
And how does it differ to a Hyperpro/Hagon progressive pair of springs?
Spring rate and lines?

Re: Spring rate and lines?
spring rate is the amount of force needed to move the spring a certain distance, i.e. 9N (thats newtons before you ask - btw, you should have spent more time in skool...anyways...) /mm, so it takes 9N to move the spring 1mm...dont bother to ask "which should i go for"...find out what you currently have, and decide if you need more or less...simples.

I know what newtons are. Right, So when you are given the option for 3 different spring rates on the website before you buy the springs, will the lengths be different or the coil tighter etc?

i would imagine that the lengths will be the same, coil rate might be different, so might the diameter of the steel that makes the spring. best bet, is like i said, find out what your current rate is in N/mm then go from there.

Re: Spring rate and lines?
if your a fat fook like me then go for a heavier spring rate, if your average weight then go for the second rate, if your dani pedrosa then lightest spring rate, simples!

Re: Spring rate and lines?
Or if your a really fast racer you might want a heavier spring. Elena Myers who was the first woman to win an AMA race at Daytona was using the same rate springs as I was a few years ago. She was lucky to break 110 lbs and I was about 200. Also I don't know any racers using progressive springs, I believe most prefer a straight rate.
