I have a 2011 specialized enduro w rockshox and wanted to add air to the front fork bc i keep bottoming it out. Is there a chart of psi to weight or anything like that to use as a baseline/ starting point? Also, at what increment should I add air in, will 2 psi be noticeable or too much and how often should i be going through the entire stroke. I mainly bottom it out when casing jumps etc and haven't felt the need to mess with it too much so maybe i should just leave it alone?

Thanks

I don't know for sure what exact fork you may have, but, yes, there are charts as a starting point, and setting sag as a starting point. And no, don't just leave it alone if bottoming frequently. But a lot of people (me included) think that it should bottom occasionally on your more aggressive rides, or you aren't getting your travel's worth. Use a ziptie on the tube to set sag and see how much travel you used on your ride.

Find your 2011 Enduro here, and check the specs for fork model (assuming it's original):

Here's your owner's manual:

You should be able to find some setup videos too, like on Pinkbike.com, but check your fork model first.

For my fox shox, the weight to psi ratio should be half your weight, but I usually run it a tad bit lower (about 5 psi lower) to get full use of my shock...but I also monitor how much I bottom it out when riding, make mental notes, and then make adjustments for the next time...

Start with the "standard" ratio, then tinker with it here and there a bit to see what works for you...but you already knew that...

A method that I've been using lately (explained to me by a couple of mech's at Jenson) is half your body weight, minus an additional 10 lbs. Again, just another method of where to start.
