I've been a loyal Fox customer for quite a while. I loved the bombproof quality of the forks, but I always thought they required a bit more tuning and maintenance and a much longer break in before they really felt optimal.
Enter the Pike. I had heard about this fork, and after demoing it at a local event, I was blown away by the smooth, buttery feel of the travel. My initial thought was "well, these are demo bikes, so they've had tons of time to let the oil cycle and the seals break in, which is why they feel so awesome". Even so, I decided to give it a go on the new Ibis Mojo HDR 650b I was building up.
I went with the 27.5 inch 150mm SoloAir platform, because I've never used a travel adjust and never found it necessary. I installed it, and was shocked at how good the fork felt right out of the box. Cycled it a couple times, set up the sag and compression, and got moving.
The 35mm stanchions give such a precise, stiff platform, that the fork really only moves in an up and down manner, there's no tweaking or torsion side to side. The action is buttery smooth, and with 20% sag, there is no brake dive or hyper squishiness when standing up and mashing on the pedals. Rebound is easily tuneable, and it's super simple to get the fork dialed, it took me about 3 rides whereas it took me an average of about 5-10 for the fox forks.
Maintenance is super easy, simply drop the lowers with a 24mm socket and a 8mm socket. The oil change intervals are also less frequent than with fox, which I like.
Overall, super super impressed, I would recommend this fork for any all mountain/trail/enduro rider, it really is a game changing fork like Nate said below.
