    Going off the review, sounds like "Biggest and Baddest" title is not entirely complimentary.

    We feel the review was a good characterization of the bike. Keep in mind the EVO we sent them had a FR type build that put it at about 35lbs. We've been regularly building up EVOs at around 31lbs. through careful selection of components for more XC usage.

    I agree with thier review for the most part; the evo isn't the world's greatest climber, but it is truly amazing going down. there has to be a compromise between the two, and the evo favors the downs a bit.
    I don't agree with their evaluation of the bike's cornering ability. I have no problem hitting corners fast and leaning the bike over. while I don't have a bunch of bikes to compare it too, it handles the corners as well or better than anything I've ridden.

    What were the other bikes to which it was compared?

    It was compared to the SC Nomad, Giant Reign, Yeti 575, and Maverick ML I believe.

    the magazine review pretty much summed up my concerns about this frame design.

    long rockers = heavy frame with somewhat poor torsional rigidity.

    seat tube angle = good seat position for the descent, but poor seat position for the climb.

    linkage and shock location = relatively high center of gravity, exacerbated by high BB relative to some newer frames out there.

    a German mag that puts frames into a deflection tester found the Nomad frame to have the best torsional stiffness : weight ratio in this category of bikes. also Nomad reviews find the seat position for the long climbs works just fine. (course the bearing issues get mentioned too).

    still it's cool that chumba is having success w/ this frame & i will be keeping an eye out for future versions.

    Try not to make assumptions or decisions based on magazine articles. The Evo is a ride that needs some real saddle time to get used to. The Evo is very stiff despite the classic parking lot flex test that some people use to judge stiffness. It tracks very true in the most technical terrain you can imagine. Sure if you land a drop a little sideways, there will be a little flex, but overall the long plates do not seriously detract from ride quality. The frame weight is more of a function of a strongly built frame. It is comparable in weight to the Turner RFX for 06. The bb height with a 6" fork is comparable to several bikes in its class as well.

    It is all subjective to opinion. I have read reviews for the Evo stating that it did not corner very well. I find it to corner very well and the riding position makes you feel like you are part of the bike and not sitting high up on it. The seat post angle is not for everyone and I can see the criticism regarding the riding position. Sliding the seat all the way forward won't work for everyone and especially taller riders looking for maximum extension.

    I honest have found the EVO climbs way better than many lighter bikes with more XC geometry. It takes a while but once you get use to it the forward BB position feels like I'm doing leg press while spinning instead of pushing straight down. I have found it to be more efficient when comes to normal climbing. I spin better and I'm not wasting energy pushing down against the suspension.

    Ever since the EVO I would prefer the EVO over even the XCL for any kind of trail riding except really steep and long climbs. Well......I don't like to climb the really steep and long trails anyways.

    And when come to the steep stuff you really need a travel adjust fork to drop the front, but any 6 inch bike you will need to do that.

    I just got home and after hearing some good stuff about the Evo I started searching some threads. Came apon this one and had a total recall, I thought did I just wake up from a dream? Nope the Starbucks cup is still in my hand! LOL's, this is pretty funny. Enjoy the new Lyrik and let me know how it rides.

    LOL small world indeed. I will post some pictures and a ride report after putting the new Lyrik on my EVO. This would the third fork on my EVO, 05 Marz AM SL, Maverick DUC32 and now Lyrik Coil. Hopefully the Lyrik will finally complement the plushness of the EVO as the first 2 couldn't. The Mars AM SL had the potential but it has 4 air chambers and I can never get it right.

    If anyone wants a 150mm marz AM SL PM me and if you are looking for new parts for your EVO or the XCL hit up Drumstix, he can hook you up as he did for me on my Lyrik.

    Thanks Drumstix! We'll definitely need to go ride and maybe hook me up with more goodies.

The boutique rides never seem to rate higher than an 8 (out of 10) so the EVO gets a great score considering. The testers are used to riding mass produced junk like giants. so don't be too concerned or subjective about this review. Readers often write in and question their conclusions and opinions on bikes.....hmmmm

    mmm perfect wording Sam... Maybe Giant and Specialized advertise in the AMBm mag more than Chumba.............

    AMB Tests

    FYI the EVO is in the fateful hands of the AMB testers again, this time we are promised that the terrain will be more rugged when testing the bikes. Competitors range from Giant Glory 0 to the Specialised Enduro SL. So not quite sure what that category is.....
    Will post when we have the details, ETA 2 months..

    Glory vs Enduro SL? Apples vs oranges?

    trust me, i take magazine articles with a pound of salt. my point was that Chumba posted a link here to a mag review that is pretty luke-warm about the evo, which is ironic.

    i am warming up to the ideas in this bike though. while i can see that for long-legged riders the seat position would be weird on the uphills, as many have pointed out, it seems like a nice centered geometry for the descents. the beefy pivot design reminds me of Ventana, which is a good thing. has anyone posted actual, measured frame weights? the MBA article reports 35 lbs w/o pedals and a pretty light build (DT 5.1 rims, DT 340 hubs, marz z1 light fork), which implies that the evo frame weighs more than the turner RFX 06. i'll search this forum for a frame weight...

    thanks for the info.

    so that recent UK review, http://www.bikemagic.com/news/articl...N/5327/v/1/sp/ , reports a 9 lb frame weight with dhx air.

    The seat position has been adjusted to 72 degrees for 2007.

    The frame weight is correct

    I just built up my med/lg and the frame was over 9lbs. The entire build (with platform pedals) was right at 35lbs. This also includes 2.5 Kendas and some crappy Spinergy FR wheels.

    I measured the angles of the small evo with the 2007 geo. The saddle height of the bike in the pic (ignoring the setback post; the measurement was to the center of the post) does result in exactly a 72 degree effective seat angle. If the saddle were raised to the same height as the bars, it would relax to an effective 70 deg angle. The actual angle of the seat tube above the midpoint weld is 63 degrees. A fully extended seat post would still seem to end up relatively slack compared to a bike with a full length straight tube with a conventional 72 or 73 degree angle.

    My video techniques can be found in this thread.

    QR 135mm

    was how mine came. Not sure if there are other options stock, but I'd bet you can get just about anything you want.

    You can use 10mm TA, I use hope's 10mm Bolt on just like their SS hub, they also have a TA option and you need to buy Hadley's TA axle.
