I think I've got one at home in a box somewhere, if I remember then I'll see if I can dig it out and weigh it when I get home and let you know.

haha sorry not the physical weight lol the weight of the spring as in its force per displacement lol, its how you rate springs for a road/race bike its usually between 80-95kg lol

1200 lb isnt it?

Doubt it 7-800lbs as a rough guess

Ah I thought you wanted physical weight for a race bike weight saving stats or something

I'm not sure on the rating, I've replaced mine with a new spring with a rating that I've already forgotten.

Having had a search about, a lot of people say 850-900lbs/in. To translate to Kilos per mm you obviously need to convert pounds to kilos and inches to mm. So, 900lbs is approx 408.kg, and one mm is approx 0.04 inches. 408*0.04 gives 16.32kg/mm. To save faffing about, it's easier to work out the conversion factor. Using more precise figures, one pound per inch is 0.453592*0.03937=0.017858 kilos per mm. Call it 0.018. So, DM's 12kg spring would be 12/0.018 or 666.667 pounds, or alternatively an 800lb spring would be 800*0.018 or 14.4kg.

I'm pretty sure if you go to some of the serious suspension companies, you can choose your spring using the model, free length and rider weight.
