I've got a Rock Shox Pike 409 coil fork, and I'd like a slightly stiffer spring as I bottom it out a little too easily. The good news is, there are several springs available. For example:


The bad news is, I can't tell which spring came with the fork, and without knowing that, I have no way of knowing which spring is one step stiffer... I'd rather not take it apart until it's time to do the swap, so if anyone knows which spring came with these forks from the factory, please let me know. I'm guessing medium, but I'd hate to buy "firm" springs only to find out that's what's already in there.

Thanks in advance!
