I bought a 2014 Process 134 about 2 months ago and I really like it. I’ve had it in Banff and Canmore and it absolutely rips on anything downhill. It feels lower than my 26" hardtail so I had plenty of pedal strikes at the beginning. The Trek may have slightly better parts but for me the Process frame makes it worth it.
My biggest knock on the Process was the weight, and the dropper post. Mine weighed something like 32-33lbs when I got it, and I find the seat post sinks when I’m sitting on it so I have to keep raising it.
The 2014 134 was a bit cheaper than the '15, and I got it well below MSRP, which definitely swayed my decision. Mine’s got new brakes and wheels so far. I’ll post a pic tomorrow.
