revised Why do shock pumps use a Schrader valve?
Added clarification on why industry prevalence is a reason for valve selection - cost.

comment Why do shock pumps use a Schrader valve?
Strength is not moot, people would prefer to not replace breaking parts to the alternative. The valve may or not be replaceable (you may need to replace additional parts as well, or it could be formed into the metal as one piece), so until I see evidence that ALL air shock models have replaceable valves, that point is not moot either. The use of Schraders outside this market is very relevant to the reduced cost to the manufacturer in design, tooling, mating equipment, and other factors that are important when they select which valve to use.

comment Why do shock pumps use a Schrader valve?
In principle, yes - if the valve is easily replaceable, presta and schrader aren't any different. Designs are already in existence for o-ring sealing schrader inserts, where as far as I'm aware there are no o-ring sealing presta designs, that'd have to be custom made. Should is another key word - because nothing says they must be replaceable. They are also replaceable, but not without tire removal/breaking the bead on vehicle wheels, which would make them a pain on many other applications.

comment Why do shock pumps use a Schrader valve?
However, it should be noted that this is the proper Schrader fitment - if you look at refrigerant/industrial/non-consumer usage. The sloppiness of car/bicycle tire pumps was not the way they were designed to be used, just a convenient afterthought.

comment Why do shock pumps use a Schrader valve?
Many of them do use regular ol' Schrader valves, so the point isn't to ram home that 'You can't fit your normal pump up' - especially since prestas don't dominate the downhill/extreme travel fork market. If it was, they wouldn't use either valve. The valve is usually a regular schrader with nothing remarkable about it, though the pump heads can use a proper threading instead of the crush-some-rubber-in-there of sloppier pump heads.

comment Does anyone make a split seat clamp?
Would I then need to remove the seat to remove the seat post, and need allen wrenches with me? My goal here is to make it quickly removable on the fly without tools.

Are there any quick release levers that are set up to use flat flanges? Usually the clamp is radiused to fit the lever. Is there a similar aluminum quick release clamp I could buy just for the quick release?

I have 2 of the equivalent of the DMR style pieces on there, and I just don't think they're strong enough. The Staff-Lok Collar would be, though - I think I'll try one of those if there isn't a bicycle-purposed one. Thanks!
