Forgive me I'm no mechanic/engineer. I have a few questions anyway..
The Pike features a new single seal system. Where the Lyrik has a pressure seal and a wiper seal, the Pike features an integrated seal that does the job of both; making it a lighter weight and more free of friction.
1) So does this mean that the external wiper seal has become the seal that holds the air pressure up, instead of the seals normally found on the inside of the stanchion?
If that's the case I won't be tempted to lose a tasty 700+ grams off my bike by swapping out my 2.5kg lyriks.
2) What's the point of going to a closed damping system for predictability on long alpine style descents when the spring system is effected by heat and pressure change? Or is it not an issue? From what I understand MXers are complaining that this effects the new KYB PSF fork so I should imagine it effects the smaller volumes found in mtb forks.
*pats trusty coil forks* It's kind of a shame they couldn't stick a titanium coil in the new Pike chassis, 2200 gram coil forks would have been schaweet. *sigh*
EDIT: Actually I assume they just mean they've changed to single lip wiper seal. Which again I've heard are trade off.
The term "pressure" through me off.
Fox have run a single seal for a long long time. I'm not familiar with the new pike but just because a fork has an oil/pressure seal, it doesn't mean it's holding back the air spring. That's normally inside the stanchion between the air valve cap and a piston on top of a rod, connected to the bottom of the slider.
