Can you hear that AAA the sound of knobby tires machinAAA over packed dirt, the soft whirr of a quad lift, the clickity clank of chain-slapped stays Sounds like the resorts are callingAAAanswer with the lively Rocky Mountain Flatline Pro. Born and raised in the heart of lift-access sending, the gravity-fueled Flatline Pro playfully styles stunts with finesse, floats doubles with composure, and dices tree-lined, twisty steeps with aplomb.
Strengths: Performance is excellent, no complaints there...
Weaknesses: Design is flawed DO NOT BUY THIS BIKE!!! Rear swingarm cracks at the mount location where thru axle screws in. I talked to several other DH riders that had the same thing happen, in the same exact spot, hence, Rocky Mountain needs to re-engineer the rear wheel mount.
DO NOT BUY THIS BIKE! Unless you want to be stuck in the middle of the season with a cracked swingarm, waiting for a warranty part, then having it break again... Life is too short to be playing games with BS like this... Rocky Mountain should re-design the rear wheel mount, then send out replacement swingarms to all the peeps that bought this bike.
It hurts me to make comments like this because I love the bike, and the performance is outstanding. But unfortunately, it is a lemon that I am now stuck with, and I do not have money for a new bike...

Strengths: 2011 Rocky Mountain Flatline Pro
Fast, stable, predictable, burly build, well equipped right out of the box. The Boxxer fork and Vivid shock work very well. The I-beam seat is great. The two position direct mount stem (seems to be made by whomever makes the Loaded Precision AMX stem) appears to be well built and the adjustment is a good option.
Once the brake pads were bedded in they seem to stop the bike very well. The Avid Elixirs are not quite as nice as what I am used to (Hayes Stroker Ace) but still work well.
Pedals well considering what it is, just have to stay in the saddle. Changed the casstte to 11-34T to accomodate pedalling steeper inclines even better.
The Maxxis Minion DHF/DHR Super Tacky tires work well in typical AZ terrain, even though the 2.5s are really small.
Weaknesses: The DT Swiss wheels seem like a lightweight choice for a DH bike. Mine came with a chain guide that did not have a bash guard. Changed that out before even riding it.
Likely as much personal preference as anything, but the stock bars are somewhat narrow for DH. Swapped them out for wider (31" / 785mm) Load Precision AMX bars.
The Boxxer fork plastic covers at the bottom of the fork fell off and were lost on the first couple of runs. Not really a RM issue.
Rear derailleur cable seems to be prone to damage, moreso than other bikes I have taken down the same trails.
The RMB pedals are very low-end and literally began to crack into pieces after a dozen runs. Swapped out to Spank Spike, which are a great addition to the bike. Not a big deal since many bikes do not even come with pedals.
My bike did not come with the short cage rear derailleur which is what is on the RMB web site specs forthis year and model. There is no need for a medium cage and it just gets in the way. This will be replaced eventually with the correct short cage derailleur.
Excellent value for a very competent downhill rocket. Ridable without modifcation, except maybe the bash guard issue (looks like the bike should have come with the MRP G2 according to online specs).
RMB took care of a warranty issue with the rear triangle very quickly. Thanks go to Rage Cycles in Scottsdale, AZ for handling it seamlessly.
It is difficult to give this bike anything less than 5 chilis. Even though it may not be 100% perfect for every rider as it sits, it is far too good for a rating of 4, and it makes an outstanding platform for an excellent DH rig no matter the skill level or terrain.

Strengths: Predictable and forgiving, decent specs, fast like lickety split and beautiful 8 inches of seemingly bottomless travel. SDG seat / post combo is not my first choice but performs well and is easy to adjust.
Weaknesses: Heavy, f-ugly colour scheme, dampening adjustment knob on rear Rock Shox is nearly impossible to reach, cockpit is smallish for me (even though it's a large) and I'm 6'1" tall, making it really tough to pedal while seated (i.e.: uphill).
It's been fun getting to know this bike. It doesn't like climbing, so I push or shuttle. It doesn't like trails with any uphill or a lot of sharp technical corners. It's very comfortable in the air, and corners like it's on rails. Can't wait to get it into the bike parks.
Strengths: everthing i have not had a single problem with this bike
this bike is bad ass the low shock postion gives you a great center of balance which when pinning it down a steap tech trail helps alot. as well the shock is postioned closer to the pedals making it very easy to throw around when needed
Strengths: stiffness, tracks well at most speeds, pedals very well for a bike of this type, very plush with plenty of feel, Ramp up in rear travel. component spec.
Weaknesses: Some break jack (might check into the floater), little on the heavy side out of the box.
First of all, for another reviewer: I don’t know what type of stab you have rode. Because for DH and fast freeride, The Flatline is twice the bike of the Kona. If all you where doing was hucks etc I could likely come to some agreement. But that’s cool; opinions are what makes our sport what is.
So I have had my Pro for almost 3 months now. I found it to be quite hard to get use to on the first couple of days. (Not like the V10) It would have had to have been the end of the 3rd full day of riding it all started to make sense. It’s hard to explain so im not going to bother. What I will say is that it practically rides itself once you get the speed up and is still flickable in the slower tight stuff.(much better than the V10 I feel) It corners like its on rails. Very impressive for a bike of this size. It handles the rough stuff very well and tracks amazingly in all terrain.
one thing I will note is that it dose not separate the rear wheel as well as some of the vp bikes (glory etc;) in the pedaling sections on the rough parts. But what it dose have is a linkage that is truly amazing in my opinion. the way it ramps up incredibly linearly all the way through the travel. This giving the impression it has a lot more rear wheel travel than most, and yet with non of the disadvantages of such a bike.
Quite amazing I think. So yes Rocky has finely made a bike for the Down Hiller that works, and works quite well!
I recommend it to anyone looking for a fast competitive DH bike.
(Note: I have a large and is set in the slackest position available with the full travel)

Strengths: Climbs well for a heavy bike, keeps you in control in any situation and makes any downhill trail posible. I've had my flatline pro for a couple of mounths now and I love this bike! It does everything you'd want to do with a downhill bike and then some. It has alowed me to up my riding to a whole new level.
Bike kicks ass! thats all there is to it. If you want the best downhill bike on the market, flatline pro is the way to go.
Strengths: Really laterally stiff suspension which gives you a solid feeling under foot. Although the rear shock can bob under really hard pedal strokes the platform is super level. With the bike setup in "DH mode" (13" BB hieght, 64 degree head angle) The chassis rail corners, all you have to do is turn and lean and it shoots you through. The frame itself is a tank, if you are able to get your hands on the frame only you'll see for yourself. Nothing flimsy about it.
Weaknesses: The head tube size is 1.5", which is understandable for a freeride bike to have, it just limits choice for headsets, especially if you need to find a reducer headset.
Get it.....as a downhiller the pro frameset is the only way to go. This bike could do so well on the world cup circuit if rocky had a rider that could compete on that level. In my opinion it takes corners a little better than a sunday just because the setup in the rear linkages is more sturdy on the flatline. The other advantage the flatline has is that you can get the front end up off the ground a little easier than on a Sunday, the sunday just wants to keep the front down at all times. Not the best for shooting big drops. The center of gravity is better than that of the konas or the Intense bikes, which makes it super easy to maneuver. This bike is the new benchmark, if you can get your hands on one.
