Rocky Mountain Altitude 70 Pro Review

26er Pro Reviews


Having spent some time with the, I was given the chance to test ride and review the Rocky Mountain 2009 Altitude 70 mountain bike. Billed on their website as a XC Marathon mountain bike. Rocky Mountain has ten different categories on their website under the mountain bike category. Talk about options! No matter, it is all about how the bike handles once it is one the trails. My off-road trail that I ride near my home is a grinder climb of over three miles with an average grade of 14%-15%. There are a number of quick technical turns and rough areas that cows have trampled through that can give any full-suspension bike a workout.

Here is what I found out about the Rocky Mountain Altitude 70 that I had for several weeks to try.

I was actually given the bike partially unassembled. This gave me a new perspective on the bike. I was surprised that the rear wheel was very difficult to slide onto to its dropouts. It took much effort because the chain stays are very short and the rear derailleur was in the way. This in theory is supposed to give the bike better climbing capabilities but having to work so hard installing the rear wheel makes me concerned if I have a rear wheel flat out in the woods. Other than the rear tire, everything else assembled very easily.

    76 degrees head angle??????
    First, from the picture it doesn’t look like it,
    second, RM website says 69 degrees, more in tune with this type of bike.
    You may have meant “seat tube angle”, but then you make reference of how steep and cumbersome the head angle is. Who are we suppose to beleive?????

  • t0mislav says:

    Seriously, Pedro is right on. Who checks these \pro\ reviews? The bike has a 76 degree SEAT angle. That is a big departure from other brands, probably the major difference in this bike and it doesn’t even get proofed?
    The wheel doesn’t go in easily? Really? When putting the rear wheel in, all you do is shift the front derailleur up into the big ring position. Short chainstay 29er riders have to deal with that \problem\ all the time.

  • Gregg says:

    Thanks for the catch, guys. The head tube angle is 69 degree and the seat tube angle is 76 degrees.

    I have corrected the text above.

  • leel says:

    I suppose those two glaring errors in the review may give some colour as to the reviewer’s experience & expertise – or lack thereof

  • Adam says:

    OMG. I might have written this shoddy of a review when I as just starting out but I’d probably do my research. Seat tube angle, head tube angle, who cares, use common sense. But complaining about mounting the rear wheel? As if its the manufacturer’s fault. Unless your talking some crazy MalWart bike, its totally rider error. By the way, Rocky is no cheapo brand; they make damn fine bikes.
    And the worst part of the review s that the “pro” let his rear Derailleur fall off?!?
    Jesus, what an idiot. I wouldn’t ave told anyone if I had done that.

  • Ecogeek says:

    If you can’t fit a rear wheel and never built a bike what the … are you reviewing anything for? If fitting the wheel w tire inflated is *really* an issue for you, then take the air out!
    NB If you have to fix a flat the air will be out already and removing will be easy! Just put it back in the drops before inflation.
    RM are one of the best. To dis cos you know nothing is a disgrace to MTBR.

  • Ecogeek says:

    Loud noise? Cos you didn’t torque. Embarassing that 1 it happened. 2 You mentioned it. And 3 it counts against the bike.
    This is one of the worst reviews I have ever read. The only info you can be sure of from reading it is that the reviewer does not know what they are talking about and so your time has been wasted.

    Isn’t this supposed to be a “pro review”?
