Which spring is stiffer 350 x 2.8 or 350 x 3.25?

My own world inside my head
Even though they are identical spring rates the 350/2.8 on an 8" travel bike would feel ever so slightly stiffer than a 350/3.25 on a 9" travel bike due to the difference in leverage ratio (assuming identical leverage curves.)
What you need to do is calculate the wheel rate:

Wheel rate = (ratio)squared x spring rate

1/3 squared x 350 = 38.88 lb/in
1/2.9 squared x 350 = 41.61 lb/in

But yes- on the same model year bike with the same leverage curve they will feel the same for a given amount of travel. Changing the length of the spring will not change the wheel rate.
Yes, that part I get fully, but the OP wasnt asking which would be stiffer between the two bike, simply pointed out that he now has a different bike, with the option of two springs for One bike, so the the two springs<given two would actually be the same.... but lets not get into the inaccuracies of steel springs> Two stroke length spring, one shock, one bike, same rate.....Same feel for that particular bike.

Sorry, this thread seemed like it was right up your alley. Perfect to feign understanding, yet not really know or answer the question...make fun of others and make useless sarchastic quips.....

Yet, overall contribute nothing...

You got it covered!

If it was truly one of your favorites, you would know the answer to my last question lies within the Bridgekeeper scene.


hehe
Crap, I missed that one. I remember when he's meeting Sir Bedeveer that Bedeveer is releasing a swallow with a coconut attached with a string.

*I just watched it on YouTube, my response should have been: "well you have to know these things when you're a king you know".
