    I have Altitude Demos on their way to Pisgah, NC and we already have a handful of the Genius 650bs... Will see what feels best.

    Nice build. I was told the revelation forks are quite a bit lighter than the fox 34.

    Have you taken it for a ride yet?

    Hey, what is the customer interest in the Genius'?
    I ordered an Altitude, but a friend who owns a shop is a little concerned about his Scott Genius order in terms of 'general public' interest in 650b.

    Demo'd the rocky mountain altitude 650b today. Great fun; I kept thinking, This rides like a 29er but it so much fun. Smooth, liked to roll, like to roll over things, quick front end but very stable; did I say that it was smooth? Don't get me wrong, I love my 29er Ti hardtail, but this was quite the eye opener.
    Just kept the pedals turning going uphill and it was making small ledges and things I don't usually clear. Big, big smile.

    Interesting view from a 29er rider. What kind of terrain were you riding it on and was it part of your normal trails?

    Thanks for sharing!

    Walnut Creek Park in Austin, TX; primarily flow trails with occasional semi-technical bits (small ledges and drop offs -- in the 12 inch range). I can say it was like riding a 29er (nice roll over, felt very stable), but without having to wrangle the large front wheel; cornered nicely. For example, if I got slightly off my line climbing, I could correct more easily. Easier to loft front end* than my 29er. I would liked to have ridden it through a rock garden, but that's a different trail.
    Some things were quite different than my usual set up (XC) and of course more oriented to trail/AM;it's a demo and you just run what they brung:
    Big, meaty (2.35"?) Nobby Nick tires
    Wide, wide handle bars
    70mm stem
    Portly (~30lbs)
    Still a fun ride and I was very impressed by the quality and design of the Rocky Mtn. bikes. I would seriously consider 650B for my next bike, although I'd go for a more XC oriented ride; don't need so much long travel suspension on the trails that I do. Who knows, maybe Rocky Mountain bikes will have a XC 650b in the next few years. My previous bike (pre 29ers) was a snappy handling Titus Racer X, and I miss that sometimes, but I feel much more confident on the 29er. The 650b seems to have that balance of stability/quickness.

    *Not popping wheelies, but just getting the tire a few inches off the ground.

    What was the Q for xx1

    I was hoping to build up something extremely similar in a Large.
    Was wondering what xx1 version you put on. The xx1 has 2 Q factors 156 or 168. I would like to use the 156 with 175 crank arms but a little scared that it might not fit.

    Thanks Chuck

    For what it's worth, I believe the RM Element (can't remember if RSL/MSL?) will run 650's. Retrofit yes but the posts I've seen seem to be a good conversion. Might be a less expensive venture into the FS XC 650 world.
    Wait whuuut, who did he tell you that!?!?....

    The Genius rides more like a 29" than the Alt. Being said the Altitude feels so much like a 26", light playful, snappy. There is a noticeable difference btw 29"/650b: uphill tech is a little more demanding, where the 29" keeps traction and has better approach. The ALT rides like a dream, just like the Element, it takes a few rides to get used to. Revelation: add Black Box Damper and your set. Meaty tires are necessary if you are coming from a 29" trail bike.... way less traction on the off camber. I planned on racing this bike on the BigMtn Enduro Series, but will probably sell it and go with Ibis Ripley W/ 140 fork or Transition. bandit 29 w/140 fork. Both can rally/climb/straight shoot, here in Pisgah like none other.

    Thank you. So you think the Altitude is way more fun than the Genius 700?
    On descends the Altitude is also the better ride?

    I don't have much riding time on my 790 yet, but I definitely concur that the bike is incredibly snappy and connects the rider with the trail in that special Rocky way that many of us Rocky fans have come to love over the years. I don't think this is a bike you buy to make trails easier...this is a bike you buy to get the most fun out of every part of the trail.

    It is hard to compare the Rocky to the Scott, as I would want it set up so differently. A DB air on the scott would be awesome. The Rocky kills it DH. I have both at the shop in our demo fleet in Pisgah Forest, NC.....good grounds for comparison. Feedback, so far, is neutral. More 27.5 vs 29 searching going on. I am now sold completely on 650b for an AM bike.

    Only one ride so far, so my impressions are limited but I think it was a good trail for the bike. Lots of very rocky climbs and descents with smoother flowy parts in between. I love that RM selected 24-36 tooth chainrings up front rather than the larger sizes that nornally come with a double ring crankset. I haven't played with the ride 9 settings at all. It was in the neutral position for this first ride and I left both the fork and rear shock in the descend settings for the entire ride. Air pressures seemed to be spot on since I got full travel on some of the bigger hits. The fit was perfect for me. I was wondering if I'd want a longer top tube with the short stem but no, 585 mm was just right. It's exactly the same on all of my bikes and that's what I like. It felt like "my bike" from the moment I started riding.

    Climbing: The bike climbs almost as well as an XC bike with no hint of front end wandering at all. Pretty impressive considering the 67.5 degree HA and 60 mm stem. Rocky really nailed the rider positioning there. It felt faster than my Epic 29 going up but of course I have no hard data to back that up.

    Pedalling: The bike feels firm under power, even in descend mode, although I saw some motion at the rear shock when I looked down. No hint of pedal feedback regardless of gear selection.

    The bike felt great blasting through rock gardens. Duh, it has 6" of travel. It would have been hugely disappointing if it didn't. It was super fun to carry so much speed through the rocks. I've mostly been riding a 29er SS with 100 mm fork, plus the Epic that I ride occasionally. It's been 3 years since I had a big bike (I had a 2005 Turner Six Pack).

    Bottom bracket height: There's been lots of talk about the trend to lower BB heights and this was the first time I got to ride a bike like this somewhere that was really rocky. Yeah, I smacked the pedals several times. I was careful and ratcheted the pedals in the bigger rocks but I hit them unexpectedly in the smaller stuff. I'll get used to it soon enough. OTOH, carving through the flowy parts was amazing. Unbelievable traction.

    The worst part of the day was a chainsuck incident. The chain can get wedged hard between the 24t chainring bolt end and the ISCG tab. For a minute, I thought I was going to have to pull the crankset right there on the trail but managed to pull it free. No visible damage to the carbon fiber frame.

    I suppose I have to mention wheel size. I was never riding along thinking, "wow, this sure is different from my 29ers". The bike just worked really well. Maybe the wheels are a big part of the reason the Altitude feels better climbing than the Epic 29? I'm going to clean and tune the Epic and put it up for sale. The SS is sticking around but I have a feeling that the Altitude is going to become my main ride even for the smoother, 3000+ foot climbing days at Ft. Ord (Sea Otter area).

    even tho chain retention with XX1 is improved, i still think on anything other than smooth, rolling terrain, it would be fool-hardy to not put a guide of some sort.

    even a top-idler, XCX-type guide would prob have prevented your chainsuck.

    Mine's 2x10 with an X0 type 2 derailleur but in any case, the chainsuck happened on a climb so I don't know how much a retention device would have helped (never used one, maybe it would have?). I started in my 24t ring because the bottom part of the climb was so rocky, then tried to shift into the 36t ring when it smoothed out. Probably not the best move on my part but I didn't expect the chain to drop to the inside while shifting up to the bigger ring.

    Nice writeup/review for ride #1. I would be very interested to see you change the Ride 9 to a steeper HA setting which also will increase the BB height. It should help with the pedal strikes and in theory improve the climbing performance even more. Takes 5 minutes so give it a try at least and see for yourself on that same loop.....but I really want to know.

    Ride #2: This was an after work XC ride at Ft. Ord, in Monterey, CA. It's a ~5 mile paved climb from my office to Laguna Seca Raceway, then I have a choice of many (80+ miles available) of trails, none of which are very technical. Lots of long climbs and descents but rain ruts and sandy spots present the only real technical challenges.

    The Altitude is a stellar climber. I'd seriously consider using it as an occasional XC race bike. Some credit has to go to the light wheels but the bike climbs like mad and still no front end wandering, even on one really tough pitch I rode in a 24-36 gear. I did have the shocks in the trail setting here and in the climb setting for the paved climb. There's substantial movement (especially up front) climbing in the descend setting but there's still a feeling of quickness.

    The bike carves fast sweepers like nothing else I've tried. None of my previous long travel bikes (Turner Six Pack, Ventana La Bruja and El Chamuco) came close to this feel. I'm thinking it's mostly BB height related.

    The trail has many little spots to grab a bit of air. I feel like my timing is off and I was flailing on these jumps. I'm used to the hardtail and Epic, where I don't have to time the preload. It was the same way with other my long travel bikes when I swapped between them and a hardtail. I'll get used to it but until I do, the Answer Rove flats are staying on the bike. No clipless pedals until I get my technique nailed.

    One nit to pick: High end complete bikes come without pedals because everyone knows pedals are a personal thing. Why isn't it the same way with saddles? Thankfully, the Fizik Tundra 2 isn't nearly as uncomfortable as it looks but certainly many people will think differently. The least they could do is spec an all black version so it would have a decent resale value. Even better, sell the bike with the saddle equivalent of cheap black resin pedals for test riding purposes and drop the price $50.

    Some thoughts on the wheel size: I really think that a good portion of what people attribute to wheel size differences is more wheelbase related. I'm not saying that wheel size doesn't matter, just that it doesn't matter as much as many people say it does. The Altitude is pretty compact for a 150 mm travel bike with a slack-ish head tube angle, even compared to the other new 27.5" bikes. It has a playful feel and is easy to move around underneath the rider. It probably gives up a bit in high speed stability to a long travel 29er due to the combination of increased wheelbase and wheel size roll-over ability but for me, it's the right tradeoff. My favorite rides are on back country hiking trails, with tight switchbacks and lots of rocky ledges. I like flow trails too, but I get my biggest grins from picking my way down a tight, steep line at lower speeds.

    I love boxes. Almost as much as my wife's cat. But I digress.


    As it popped out:


    After a few critical changes:
    (38t rear)



    A sturdier fork (TALAS 36)


    And the really surprising part, even after adding the 36, taller cog, and a cushier saddle:
    (but lighter bars, front wheel, stem, and a few other bits)


    This thing is gonna be baddass.
    Only critiques are with the TOTAL integration of the SRAM cockpit parts, and the difficulty of dealing with cable changes internally (one of the few things I hated about my Klein, anyhoo!)


    I have a mostly complete XT kit ready, but the Reverb lever is integrated into the brake lever and shifter, the rear brake is integrated into the shifter, etc...I think I will order everything to be 'separated' again from now on.
    Other than that, quality is outstanding, finish is great. Gonna be a rocker. I REALLY want to thank Rocky Mountain Bicycles and Habitat in Driggs for helping me get set up with this. HUGE gratitude here, which I will repay with dirt work!

    Damn, that came out about a pound lighter than my complete 790 MSL with full SRAM X.0 (medium frame, stock build including pedals). Maybe my scale is off?

    Or mine!
    No pedals, there is a pound right there.
    My front wheel is a Crest on a hope II, alloy nips. Tubeless. Probably over 2/3 of a pound right there.
    Can't wait to ditch the CDT control as well.
    That thing is BULKY.

    Got my 770 3 days ago, have been on one ride at Lefthand OHV outside of Boulder, Colorado. Perfect first ride with steep technical sections both up and down. It was heavily raining during parts of the ride- the bike is no longer pristine. I have never purchased a complete bike before- I typically buy a frame and move parts over. So nice.
    I rode it with the ride9 in the 68 HA/ approx. 14" BB height setting. Kept shock in descend and fork in trail mode, need to play with these settings some more. As previously reported I'd like to echo impressed with climbing, especially in sit and spin mode. I've been riding singlespeed or 1x9 for several years now it really was nice to have the 2x10 for these particular climbs. I was nailing the tougher bits. I was expecting to have to get a dual position or talas fork for this bike but the front end did not want to get up as previously mentioned. The altitude was definitely superior with respect to climbing versus the intense carbine 27.5 I demoed.
    The first descent was ok but troubled by suspension set up. Rebound was too fast in rear, too slow up front. Adjusted and climbed for some more and second descent. On a little transitional descent I pinch flatted the front, a 29er tube was put in for me. Second descent was ripping fast. Felt totally in control-only noticed the suspension working and trail- it was a great feeling.
    I obviously got to play around this thing some more and set up for me. All in all not bad bone stock. Thumbsup to overall design, fit and finish of bike. Thumbsup to XT plus. Questioning if I should even install bionicon chain guide. Nobby nics were good. Avids weren't as bad as expecting but really looking forward to throwing on Formula ROs and going tubeless. All the lines up front of the handlebars is a mess.
    Bone stock large 770 w/ candy pedals weighed 29.5 lbs. Was expecting it to be a little lighter, but on the trail made no difference- bike sure felt light.
