<< can the length of steer tube on the rock shox be shortened via cutting saw? Will this damage the fork or impeded its performance in any way? Thanks in advance. -dejacky >>
There is no problem cutting the steerer of any threadless fork. This is a necessary part of fitting it to a bike. If your bike has an older, threaded headset, it will make it somewhat costly to fit a newer, threadless fork, since you will also need a new stem and upper headset cone and race. Assuming your bike is less than, say, 6 years old, it will definitely be threadless and the fork will be an easy install. I would not advise installing it yourself since cutting the steerer is a bit tricky, and you need a proprietary tool to set a star-shaped nut into the steerer once it is cut. Make sure that whoever installs it leaves you with some extra steerer length so you can throw some spacers underneath your stem, leaving you the ability to adjust its height later.
