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.

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

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.
