Gear Review – Rocky Mountain Altitude 750 MSL

Rocky Mountain Bikes of Vancouver, British Columbia, has been building killer bikes for over 30 years.  For 2013 they have taken an old favorite, the Altitude, and crafted a beautiful 650b bike. 650b’s have claimed the middle road of tire diameter, landing between 26 inch and 29 inch tires at the 27.5 inch mark. Many bike critics are agreeing that this gives the rider the best of both worlds: quick turns and fast travel both up and down.

The new 750 MSL is a solid uphill climbing machine. Able to keep it’s momentum through switchbacks delivering that little extra roll you sometimes need when plowing through loose rocks or slippery roots, the Altitude is a sweet ride.  Of course, the fun really begins when it’s time to start heading down. The FOX Shocks provide a plush descent through moist, rocky single-track as well as a smooth ride over rough downhill trails. Whether floating through a jagged rock garden, effortlessly landing a big air or stomping a 10 foot drop the Altitude is there for you like a true friend.

Rocky Mountain’s fully adjustable Ride-9-System offers nine different geometry and chassis settings, allowing you to fine-tune the Altitude to your riding style and weight.  This patent pending system allows you to adjust the head angle (66.6°-68.3°) and seat angle (73.6°-75.3°) of your bike.  It’s not necessarily an adjustment you would make trailside, but being able to decide these angles when building your Altitude will allow you to get the most out of this amazing trail bike.

The rear shock is adjustable without missing a beat, a click of the thumb and the FOX Float Remote CTD shock goes from climb to trail, with your eyes still focused on what lies ahead. Another flick of the thumb puts the rear shock in descend mode.

To top it off, having the option to adjust your seat post height from climb to descend, or anywhere in between, without having to stop and get off your bike to flip the quick release, makes the ride even smoother. The Rock Shox Reverb seat dropper post that comes with the 750 Altitude MSL gives you these options without having to think about it.

This bike dominates on both the up and the down.  With a top of the line SRAM component build, fully adjustable angles and the extra oomph of bigger wheels, this bike will allow you to have a one bike quiver. It really can do it all. Based on the way the Rocky Mountain 750 MSL rides, it seems the 650b wheel size may be here to stay.

Honestly, it’s hard to find much of anything to complain about. Looking at the specs and pricing throughout all the companies now making a 650b, the price tags seem a bit excessive.  Also, you might find yourself going a bit faster than is comfortable; is that a bad thing?

Who should ride this bike
The Rocky Mountain 750 MSL is aimed at a recently defined category of pedaler: the Trail Rider.  Everyone loves to point it downhill, but as you know “you gotta get up to get down”.  Being able to conserve energy and pedal efficiently on the ascents and still feel confident your bike will perform on the downhill is priceless… well, almost.
