Hi Andrew-
I'd like to correct a few things in your article here. My name is Dave and I did the thru-shaft project on the rock shox side of things.
_No dynamic internal floating piston (IFP) means no nitrogen charge. No nitrogen charge means the new Thru Shaft shocks are fully serviceable at your preferred local mountain bike shop or by any rider with the time, confidence, and tools. _
Thru-shaft does have an IFP- which is always connected to the rebound side of things (through the upper damper shaft). True it doesn't move with each stroke, but to say it doesn't have an IFP is false.
Also all Deluxe and Super Deluxe shocks are user serviceable. They simply require a special fitting and a special pump for higher pressures- available through most distributors. Same place you would get the special bleed tools to work on this shock.
_This reservoir gets pumped up to 250psi. It's a good idea to pump it up when checking main pressure. _
Please don't check IFP pressure when checking air pressure- there is no need to do so. The volume is so tiny- gauge loss on a normal shock pump will be 100psi or more. Then you have people thinking their IFP is leaking or low when it is not.
Finally the leaking issue- some shocks (too many) had the lower shaft seal rolled or cut on the assembly line during the initial production run- this issue has been solved. The good news is that if you got a bad one- it leaked immediately on the first ride. If the seal is good- the shocks are pretty bombproof.
Lemme know if you have any other questions.
