First Look: 2013 Rocky Mountain 650B Altitude Trail Bike

The correct number of bikes to own is N+1 where N is the current number of bikes owned. In a perfect world, a cyclist would own a bike for every application from downhill to road, but even in this alternate reality, one bike would always reign supreme.

For the avid mountain biker, the queen of the harem will always be the trail bike.  From sweltering climbs to treacherous descents her ability to tackle any obstacle is unparalleled.

The all new Rocky Mountain Altitude is this kind of bike. The  new 150mm travel rig is well thought out and introduces a really unique tuning mechanism. There’s only one caveat, it only available with 27.5″ wheels. Rocky Mountain made the decision to design their quiver killer around the newly popular tweener wheels because they claim its just right for the application.

UPDATE: Ride video added at bottom of post.

Ride 9

The standout feature of the new Rocky Mountain 650B Altitude is their new Ride 9 system which allows the bike to be tuned for an individuals riding style and weight.

Slight adjustments in the shock location can dramatically alter a bike’s handling. The dual rotating inserts allow you to completely personalize your bike. The idea is to flirt with different options, find the one you love, and proceed to settle down and start a life together.

The two interlocking inserts provide nine possible geometry and suspension configurations. Rotating the pieces maniuplates the position of the rear shock and alters the head angle (66.6°- 68.3°), seat angle (73.6°-75.3°), and bottom bracket drop (-10mm to +10mm), as well as the force required to bottom out the suspension.

Lost? Don’t worry. There is a web app. Simply rotate the dial on the right and the simple chart below will provide easy to understand feedback on what each setting accomplishes.

The short and skinny can be understood from staring at this diagram intently for the next few minutes.

Essentially, the front and back adjustments steepen and slacken the geometry and the up and down fine tune the progressiveness of the suspension. When the shock is mounted in the “heavier rider, lower starting pressure” position, Rocky Mountain claims heavier riders can run between 20-30 lower PSI in the custom tuned Fox CTD shock than when the bike is set in its stock configuration.

The Bike

We weren’t allowed to weigh these bikes because they’re all first production carbon and prototype aluminum frames. As a result, they’re a little heavier than the final production bikes.

All of Rocky Mountains bikes are produced overseas but their aluminum and first run carbon prototypes are all manufactured at their facility in Vancouver.

The Altitude cockpit has more controls than your average Cessna. In addition to your usual trail bike essentials such as a dropper post, the bike is outfitted with a handlebar mounted shock adjustment.

The bikes clean lines are accentuated by the internal cable routing. Everything but the rear brake hose is tucked away cleanly. Carbon frames will have internal rear shock remote cable routing while aluminum versions will only offer external routing.

The seat post clamp is covered by a rubber sheath in order to protect the frame interior from the elements.

Since the Altitude is spec’d with a BB92 press fit bottom bracket, Rocky Mountain includes ISCG-05 mounts for those who prefer to run 1x drivetrains.

Stainless steel anti chain-drop plates are molded into the chainstays to prevent damage to the carbon fiber frames in the event of a dropped chain.

My apologies for the out of focus image

The wheel is locked and loaded via a Shimano QR E-Thru axle. Unlike the Syntace or DT systems which have a tendency to come loose, this QR method threads into the frame and clamps into place.

The fixture which the thru axle is threaded into is held by a small Allen which is just visible above the dropout. All Shimano equipped Altitudes will ship with their recently introduced direct mount derailleur hanger.


Rocky Mountain expects frames and completes to be available in late winter.

Isn’t there another formula where the correct # of bikes to own is N-1, in which N is the number of bikes it takes for your wife to divorce you?

I like the idea of this bike and the adjustable linkage. Rocky has really been coming on strong for the past two years. Great bikes, suspention design and kits. Just please change the brakes to SLX or XT.

Not in love with the black/vomit green pattern, but still that right there is gonna be the frame of my 2014 trail/AM bike.

It looks like the guy in the Rocky Mountain bike naming department failed to notice that Scott already launched a line of 150mm 650B bikes with ‘700’ nomenclature….
I’m sure he’ll notice at some point..

I have not seen it in person, but looks like carbon/ October Aspen to me. Lighten up Francis! Can’t wait to ride this one.

Simply put: the best bike I’ve ever had it. It rolls amazingly, climbs with easy, very agile, and descends with tons of confidence. Right on my second ride I’ve done two very technical drops that were in my bucket list for a couple of years. I just didn’t have enough confidence with my previous bikes.

I traded my Santa Cruz Blur LT (Talas 32 150mm fork) for this bike. One problem with the Blur was the 32 fork that dives and flexes. The Altitude comes with Fox 34 which is awesome. 27.5 rolls way better than 26 and is just as fun to jump, drop, do switchbacks.

The straight geometry also proved amazing on climbs. As my buddy and I mentioned, you climb with little effort. Rider 9’s shock adjustment is also another great plus as you can customize the suspension for your taste and even to different rides.

I’ve fallen in love with Rocky Mountains while riding an 26 altitude in Whistler’s cross country and the Flatline downhill at the bike park. The 650B Altitude is just another excellent bike from these guys. The best of them for me!

Besides the technology on it (internal cable routing, 142×12 thru axle, etc..) the bike looks awesome. The carbon frame is beautiful and has big diameters that make it look a very tough bike in a outstanding great looking package.

The only change I’ve done to the bike was swapping the Noby Nics for Hams Danf for better fit with the terrain where I ride. Also made it tubeless.

I am in love 🙂

Three rides on my 770 so far, changed the tires out to maxxis ardents.
Have not gone tubeless yet but soon.
Simply put this bike is amazing and fun.

the new Trek Fuel 29ers blow this away in pricing….they are going to be priced nearly 1K less for equivalent specs
