Pros: Loads of adjustability, excellent damping, soaks up the bumps/roots/rocks/dips/everything with ease, keeps the front tire planted, 15QR thru-axle.
Cons: Can't quickly and easily (on the fly) change fork travel length, need to stop. Refresh work is best left to the pros = costs a bit.
Recommendation: Picked up a new bike and effectively doubled my fork travel. And I moved from a very basic front fork to one that has the ability to adjust all aspects of fork operation. Holy crap was it a huge step up.
I don't have any similar experience to gauge this fork on, but this fork has brought loads of confidence to my riding. I'm no longer slowing down for every root garden out there, and I'm flying down hills with little fear of what the trail will bring to bear. Coupled with the RP2 shock, this fork is amazing on my Trance X2.
Pros: Adjust plenty on the fly, lock out is great if you have blowoff set properly.
Cons: Like all things, they need to be maintained for seals, fluids etc...it starts to add up.
The lock when activated sometimes changes your compression settings too on the back and forth.
Recommendation: I've been roling the 140 RLC for several years now. Great forsk when mated to the proper frame..mine an SC LT2 (updated VPP).The 100mm setting feels like you're plowing. If I drag teh bike for some XC race on more demanding terrain, I rarely click beyond 120mm and usually set it locked with the blow-off dialed medium to let through on the hard ones. One 140 comes in handy on the steeper grounds with bigger hits.
It's a great all around fork for the AM/Trail oriented frames.
Pros: Adjustability. All round performance. Durability and reliability.
Recommendation: This is a great all-purpose fork. I've abused mine for 3 seasons and it shows no signs of slowing down. It's not as plush as my old 'zoke coil, but its clearly superior in every other way and I always feel like I have the right fork, regarless of what I encounter.
Pros: Easy to set up. Plush bottomless feel without brake dive.
Recommendation: I set this fork up in one ride. There is no need for the lock-out in the low or medium setting. This fork is great! Now I realize that the stable platform fork that was replaced was good technology but not needed and too much hassle for a fork.
