Looking at a bike with this fork (devinci troy xp). I think I may want to go 150 down to 140mm. Unlike older fork where you just move a spacer, it looks like a new shaft kit is required? Can anyone for sure verify this? If so how much is the kit and is it easy?

I see you can add bottomless tokens, but looks that's to reduce air volume only.

I have a pike on the way for my new Rip 9 (also on the way). I have read of people cutting in half the tokens. As for the air shaft I have considered going to a 130mm if I find the need to reduce travel. I read on here the new shaft runs about $40. My dealer said that price sounds right without looking it up, labor would be about $30. Parts seem very reasonable compared to Fox.

You do indeed need a new air shaft. A year or two ago Rock Shox started using a dimple in the wall of the air chamber to balance the positive/negative spring pressures. This means that the air piston has to rest at the very bottom of the air chamber, and you cannot use travel spacers. It was a while ago I looked up the price, but I think they are about $60-75. About the same as a Fox air shaft if I recall correctly.

you may want to read through this blog, one of the other forum members did the conversion, and cataloged the whole process with pictures. very useful if you wish to change the airshaft on your pike.
