I've also just bought a pair of 2013 Revelation RLT's with the new style pushloc. I didn't actually want the pushloc but the forks were going cheap. I assumed I could just not fit the push lock, but didn't realise the spring keeps the forks locked so you basically have to use the push lock.
Initially, I plan to put a gear cable inner into the top cap so that the nipple is held by the end stop that normally holds the outer of the pushloc cable. Then I can twist the blue knob to the unlocked position (under tension of the spring) and tighten the grub screw down on the cable, thus fixing the blue knob in the unlocked position.
Ideally I would like to be able to lock and unlock manually by removing the spring, as suggested by bruneep. I've read elsewhere that you can also add an o-ring to provide a bit of friction so that the knob stays where you put it.
My question is, once it is modified, does the springless blue knob then behave exactly the same as a proper manual blue knob (apart from being harder to turn because it doesn't have the little lever on)? It looks to me like the blue knob on the pushloc version only turns about an 1/8th of a turn to go from locked to unlocked. Is that the same as the proper manual lever does?
