Strengths: light, climbs very very well, durable, and descends just as well as it climbs. Overall excellent Trail/All mountain bike.
Weaknesses: Its a give and take weakness, but the bottom bracket sits fairly low, so pedal strikes are common as if you were riding a 29er, but by it being so low, it shines in the turns and going downhill. Also for a carbon frame it could be a tab bit lighter. But a 6lb frame is pretty damn light and im sure the extra weight is for durability, so again, not so much a weakness, but something worth mentioning.
I purchased the frame separately, and assembled my own components. I installed a Rockshox revelation dual air XX fork, Shimano XT brakes 180mm front 160mm rear, Easton EA70 wheels, Continental speed king 2.3 front tire, Maxxis Larsen TT 2.2 rear. Shimano XT crank and rear cassette, 2X9 system with a Ethirteen bash guard. Shimano XT front and rear derailleurs. Specialized Backlite dropper seat post (new 3 position), normal RP23 rear shock, Shimano LX shifters.
when said and done, this bike is really light for what it does. I hit all types of trails, and coupled with this fork, this bike is AWESOME! as what i mentioned in its strengths, it climbs very very well! lots of acceleration and stiff. Need to keep up on the maintenance, basically periodically lube the pivot points after long rides, and you will be rewarded in the end. when descending, this thing tracks well, does not wander or go off course, with a dropper seat post this thing is phenomenal.
i am basically using this bike as a trail/all mountain rig, so my normal outings consist of long climbs and downhills. i enjoy the fact that i can climb with others running 29ers no probs at all..the acceleration is its advantage, and no worries on losing traction while climbing, its stiff and sits you right in the saddle without hunching over all the time..and thats pretty damn impressive considering i tossed on a 150mm fork.
For somebody to give it 2 chilis cause it does not "shift well" makes no sense at all...i would have rated its components 2 chilis as that has nothing to do with the frame's performance! put something half way decent on this frame and you will be shocked.
i have done probably 100 miles easily on this frame so far, generated a ton of chips, which i suggest to grab some clear nail polish and cover after each ride to protect the carbon.
Overall, this is an outstanding frame, if you are looking for a nice trail/all mountain rig, this is a great buy..you wont regret it.

Strengths: components, weight, ride
Weaknesses: none yet
Smokin' deal on a close-out, with carbon frame, XT/XTR. About 28 pounds for a 19" bike, 140mm front/rear; upright seat tube and relaxed head tube angles give me the climb I like with the descending I crave. I will try to write a long term review, but would recommend it to someone looking for a great bike in the $2-3K range.
Strengths: Great climber! Suspension action is good
Weaknesses: I experienced the worst chain suck with the Raceface Crank! Stock tires sucked too
I’ve had many bikes and am just coming off a Rocky Mountain Slayer. I liked the Slayer but I need more help going up the hill than going down so I needed a new machine. This bike climbs better than my old Epic! Switched to a 2X10 drive train and life is good. If you get this bike I would immediately pull off the crank and sell it. It takes a bit to get used to the steeper angles but I do like the platform. The carbon frame is super stiff and glides over the rocks around here. I am really happy with the bike.

Strengths: Handling, suspension, brakes, lightweight, good components (except for chainrings)
Weaknesses: Chainsuck ,raceface chainrings are poor quality.
I'm happy with this bike except for the shifting. Race face chainrings are very low quality on this bike. Rocky Mountain dropped the ball on that one.
Having said that, It climbs and handles tight twisty single track very well. Suspension works well and was easy to adjust. Brakes are much smoother than the avid's on my cannondale.
Bottom line: if you don't mind paying that kind of money and having to upgrade right out of the box than this might be a good choice. 5 chile's with decent chainrings, 2 chile's with the raceface chainrings.

The grips are awful
I am a french customer (so excuse my english), I am very happy to have this bike : it clims very well and downhill better than ETSX (my previous bike) - suspension does work great. Light bike, amazing frame. The bike is always asking for more speed, it is very nervous.
The equipment is tremendous, I love the modulation of the XT brakes. The transmission works well, careful of chain-shuks.
Wondering if this is possible, saw a few people try this on the element with no luck, was wondering has anybody tried this on the trail Models? Such as the altitude, or maybe the AM rides like the slayer? seems like there is enough room? I installed a 2.4 in the rear, no rubbage...but that's prolly ... Read More »
Seriously awesome experience. But here's the catch : I'm actually worried about the bike as it makes you terribly and insanely better at descents. It's just a new riding experience. I gained much more speed in decents and now I'm worried to damage bearings all over the place as our trails are pretty ... Read More »
Somehow the bolt (two pieces) that hold the rear swingarm together came out completely and was temporarily lost. This is the bolt set that is right above the rear derailleur.
So I called Rocky and they sent a new bolt set. However, what they sent not only has the two bolts, but two plastic busin ... Read More »
4 months after its purchase, I finally got my first ride on my bike. I am 205 lbs clothed, 6'2" with 35" inseam, and have a XL, so I got a 1 inch shorter stem and narrower bars and it fits perfect. I also swapped out the cranks for the XT's so I don't run into chain suck problems in the future.
