I picked up a 1999 (I think) Silk Tour 700 for cheap with the thought of making it into some sort of cool drop bar 29er/Monster Cross. I just serviced the fork and put 5w fork oil in. The air bubble in the damping and lock out is now gone, but it's still a really soft spring and it bottoms out quite easily. When I had it apart I didn't see a way to get the coil spring out, do I punch it out from below? Are there stiffer springs available? Is 5w fork oil standard or should I go heavier? The fork action is super nice and feels nicely damped. Hoping somebody here knows about these forks. The fork is the same as a Silk Path from what the decal says when I removed it from the frame and looks to have about ~30mm of travel. Thanks in advance for any info. I think this just may be a cool bike for crusing the trails.
