well ill try to look while im saving up but i swear no one sells 7.5 x 2 dhx on ebay... and im pretty sure i did the calculator right. i weight 135lbs, my bike has a 2 inch stroke and 6 inches of rear wheel travel... someone double check please thanks
Since you ran the TF Tuned calculator, I ran the Fox, which is a bit different; has a few more things to tweak/assume, but doesn't offer differing results for suspension type like the TF Tuned. I see you used the 33% sag setting, fwiw the 28% sag setting it offers came up with a 442 # calculation.
I ran it at the 135 you mention (Fox specifies total riding weight), but you could try higher weights (especially if you're growing). Fox has a rear bias setting, nominally 60% so I used that for three different sag settings, and a suggestion of 70% for dh so did that with the dh type sag. It also assumes one turn of preload (and a 60% end coil effect estimate).
25% sag, it calculated a 485 # spring, suggested you order a 500 and estimated 23.1% sag with the recommended spring.
28% sag, calc'd 433, recommended 400, sag 29.1%
33% sag, calc'd 368, recommended 350, sag 33.5%
Running 33% sag and 70% rear bias, calc'd 429, recommended 400, sag 34.2%
You might consider what sag you want to run at...
