My primary spring is dark green-pink. It may seem like a black color in the flashlight, but in fact it is dark green. I cannot find this kind of color spring in any of the available charts on the internet, anyone has idea what kind of spring might that be? I saw this color in secondary team spring chart, but secondary spring would not fit into primary right? I bought the sled slightly used so I am guessing previous owner put this spring in there, I only saw new sleds coming with black springs. I should probably replace this spring with another spring of a known parameters, any suggestions for a primary spring for tree riding?
