    Why would anyone in their right mind increase rotational inertia and unsprung weight?

    Trollin for 29er insults, or are you serious. If your serious, most DHers would stick to 26, although current DHers with 29er XC/AM might give it a go. Also, current 29ers XC/AM who have an interest in more travel would also be interested.

    29 inch wheels are a crutch for riders with sub-par skills

    Ohhhhh, look at the rooty, rocky trail I just rode through because I have monster truck sized wheels!!

    no
    You better just go ahead and drop that seatpost down to the reflector... the trail gets pretty rough down there.

    That's dumb. What's to stop me from using the same reasoning to say suspension is a crutch for the week? How about wide tires? Disc brakes? The whole point of racing DH is to do what it takes to go down a hill as fast as you can. If bigger wheels are beneficial, why shouldn't people use them?



    That said, I am far from sold on 29ers, even for XC use. Would I love to take a spin on a on the 951 29er? Yes. Would I buy one? I'd need to ride one to know.

    Suspension is a crutch - along with everything else you said.

    If you want to hone skills I recommend riding a minimalist hardtail rig as fast as possible. Then when you jump on the dh bike you will be choosing better lines, properly pump terrain and carry more speed.

    I stand by my statement about 29 inch wheels.

    Wow, you are retarded. Lines for a hardtail aren't always lines for a full suspension bike. Quite the contrary a lot of times. It may be the gnarly line, IE the one too gnarly for a hardtail, that is faster.

    Although riding a hardtail can be very beneficial.

    WEAK rebuttal

    Riding gnarly lines on your hardtail will make you faster on your fully.

    you might be slower on your hardtail compared to your DH bike but thats the point of my arguement. (as silly as you may think it is, none-the-less)

    All those things were proven on motocross motorcycles long before the MTB adopted them. Where are the big wheels for MX bikes?

    The people who design, engineer and race the fastest two wheeled off road vehicles on earth discovered long ago that the forces generated by big heavy wheels severely limit control at speed.

    Did you read the second half of my post? I was in no way claiming that 29 inch wheels were an improvement over 26s. My point was simply that bagging on 29ers for potentially being advantageous is moronic.

    What long travel Freeride bikes 6+ inches travel or DH bikes exist in 29er form? I can't find anything more extreme than the Niner at 5.5". Thanks, Joe

    I did, and I know where you're coming from. My comments were not actually directed at you, but more as food for thought for those that may be confused by the "29ers are better for everything and everyone" type of marketing that is being shamefully thrown at us from every direction.

    Personally, I think those that spout you need a hardtail to become any sort of a skilled rider are full of themselves. I don't think you need to attend the school of hard knocks to ride , enjoy or excel @ mountain biking.

    Last time I checked, a MX track and a DH race course are almost nothing alike... also note that MX bikes have over double the amount of travel as most DH bikes and have a powerful engine to propel them... it's not really a valid comparison.
    Speed has never killed anybody. Suddenly becoming stationary... that's what gets you.

    Nope, don't see me riding 29" any time soon...

    I'm skipping a generation and waiting for the 32" wheels.

    35s would roll over stuff so well you don't even need suspension on WC DHs
    You better just go ahead and drop that seatpost down to the reflector... the trail gets pretty rough down there.

    29 for trails.. not DH.

    29 will always be superior in trail ridding but never in downhill ridding. If you put a full XT build kit on Giant Trance X it weights 27lbs... if you put the same build kit on a Niner R.I.P. 9 it will weight 30lbs... not to big of a difference... but if they start making 29 wheels, forks, frames, and tires that withstand downhill ridding then your dealing with way more weight than you need.

    if sam hill does it then most of the people here will too. the problem is matching up tire/fork/wheel sponsors. if someone can do it and win then more will and things will change. i just want to ride my bike as much as possible. if 29 makes me faster than you i would.

    There are so many things wrong with this statement I don't know where to start...
    #1- 29ers are NOT "always superior in trail "ridding""(spellcheck, dude...) That depends on what kind of trails you ride, and what your riding style is. I have tried 29er bikes, and they are NOT "superior" for ME on the trails that I ride (more FR than XC). I'm sure they are better for certain riders on certain kinds of trails, but not for everyone.
    #2 "never in downhill "ridding"". Never? Absolutely Never? Not for ANYONE? How do YOU know? The argument you offer is about weight. Since when has weight penalty ever prevented DHers from exploring and successfully using new technology?
    My personal opinion here is that 29ers are relevant for certain riders doing certain types of XC riding, but I really doubt that they are the best size to use for FR or DH. However, I would be VERY interested in taking a 29er gravity rig for a test ride before forming opinions with words like "always" and "never". The test ride would have to be cheap or free, though, I'm not gonna invest thousands of $$ just out of curiosity.

    Who are you... my mom, why do you care how I spell?

    Well lucky for me I get to ride 29 all the time... for free! I have owned a R.I.P. and a Reign X and I have to say on almost everything (unless it was super DH specific) the R.I.P. bettered the Reign X, up and down! 29 are not just for XC... people who say that obviously haven't seen the limits of a 29. Maybe instead of just test ridding a 29 you need to own one... you cant nearly know how to ride a 29 in two rides (they ride way different than a 26in.) I'm not argueeing just for 29... I own a Glory, and in no way is there (and I hope there never will be) a 29 that I could ride the same stuff that I ride on my Glory. I have also ridding the WFO... great bike, but still no downhill bike. So no worrys about me saying "always and never" cuz I have ridding and owned the best of both sides. My argueement is not just about weight... once you start moving a certin speed I think in tight turns 26 will always be superior. You just cant lay over a 29 like you can a 26in... it takes a lot more effort. But weight is an issue.. pro downhill ridders wouldn't use all ti bolds on their bikes if weight wasn't an issue. Come on, we all know we want light bikes.

    My finaly answer:
    If your not ridding DH, freeridding or dirt jumping and your not poor... then you should be ridding a 29.

    And if you dont like mountain bikes than ride a 20.

    Hahaha.. you could say that about everything. Do you think hydrolic brakes, suspention, nine speed cassettes, light weight parts, and good tires are all crutchs for the weak as well??

    You know, lots of people return 29s becuase the gear reatio is too difficult for them. Doesn't seem like a crutch for them.

    Yes, as a matter of fact I do.
    But all those things are cool, 29ers are not. They look stupid.
    And I know lots of people who return 29ers because the gear ratio is LAME!

    First off, I do not own a 29er. That being said, Why should a 5' dude and a 6'5" dude ride the same wheels size. I see them as a good option. And untill we all ride one its just a bunch of waisted time saying its great or not. Im not going to bash it just because its not currently cool. Im sure if Hill was on one the world would all praise the 29er. I think in the coming years we will see more of them and they may be the right bike for some. There is no "right bike" for all.
    Enjoy every ride!

    what about a 29/26 setup. no need to mess with the rear end and just drop the front to 7in or whatever. the increased dia and tire contact seem like a good idea to me. in the front at least.

    anyone try this out? duh i doubt it unless you have a dorado or shiver unfortunately.

    Whenever these threads come up I always picture the people who swear the most energetically that 29er DH will never work to be the first ones who'll line up to buy a big-wheeled big bike if their favorite DH superstar wins a race on one.

    Bottom line, as M-dub says, taking sides in this argument is a waste of time since none of us have actually ridden a 29er DH frame built with 29er specific DH parts. It's really amazing how everyone on this forum will preach at people to "only buy a DH bike if you get a chance to test ride it" and yet are so willing to discount that bigger wheels might work without even SEEING such a bike in person, let alone riding one.

    [QUOTE=kyle10bike]Who are you... my mom, why do you care how I spell?
    I guess it's just a basic courtesy thing. If you want others to read and consider your opinion, couldn't you take the effort to communicate in a way that comes across as somewhat thoughtful and intelligent? Sorry, maybe I was a bit rude on that one, it's just a personal pet peeve. Spelling really isn't that difficult...

    My finaly answer:
    If your not ridding DH, freeridding or dirt jumping and your not poor... then you should be ridding a 29.

    Well, I'm not too poor to ride whatever I want, but the rest of that statement pretty well rules me out as a 29er candidate I ride XC so rarely that it's not worth buying a bike for it, and when it comes to All-Mountain, my idea of AM would be a lot of people's idea of FR...
    Anyways, ride whatever you want, but don't be such a close-minded arrogant jack@$$ as to tell others "you SHOULD be on a 29er" instead of acknowledging that it's perfectly OK for others to ride whatever makes them happy.
    And one more thing... you have "ridding and owned" the "best" of both? Are you saying a Glory is absolutely, hands down, the best DH bike out there? Care to qualify that statement? I'm sure a Glory is a capable rig, but.... Never mind. I should just go back to picking on your absolutely atrocious spelling. Seriously, did you even graduate from 6th grade? You must have butchered the spelling on well over half of the words in your post. It makes you come across like you're not even old enough to have made it past 6th grade. I swear I can feel brain cells dying and my IQ dropping every time I read one of your posts.

    And one more thing... you have "ridding and owned" the "best" of both? Are you saying a Glory is absolutely, hands down, the best DH bike out there? Care to qualify that statement? I'm sure a Glory is a capable rig, but.... Never mind. I should just go back to picking on your absolutely atrocious spelling. Seriously, did you even graduate from 6th grade? You must have butchered the spelling on well over half of the words in your post. It makes you come across like you're not even old enough to have made it past 6th grade. I swear I can feel brain cells dying and my IQ dropping every time I read one of your posts.
    Holly shyt!! You really hate peeps with poor spelling skills. lol.

    Well lucky for me I get to ride 29 all the time... for free! I have owned a R.I.P. and a Reign X and I have to say on almost everything (unless it was super DH specific) the R.I.P. bettered the Reign X, up and down! 29 are not just for XC... people who say that obviously haven't seen the limits of a 29. Maybe instead of just test ridding a 29 you need to own one... you cant nearly know how to ride a 29 in two rides (they ride way different than a 26in.) I'm not argueeing just for 29... I own a Glory, and in no way is there (and I hope there never will be) a 29 that I could ride the same stuff that I ride on my Glory. I have also ridding the WFO... great bike, but still no downhill bike. So no worrys about me saying "always and never" cuz I have ridding and owned the best of both sides. My argueement is not just about weight... once you start moving a certin speed I think in tight turns 26 will always be superior. You just cant lay over a 29 like you can a 26in... it takes a lot more effort. But weight is an issue.. pro downhill ridders wouldn't use all ti bolds on their bikes if weight wasn't an issue. Come on, we all know we want light bikes.

    My finaly answer:
    If your not ridding DH, freeridding or dirt jumping and your not poor... then you should be ridding a 29.

    And if you dont like mountain bikes than ride a 20.

    Glad, for once, that I'm poor! Now I have a logical reason not to own a 29er!

    Probably not going to be a big thing anytime soon.

    I have owned and ridden 6+" travel 29ers for almost 5 years, and rode expert-level DH for about 5 years prior to that on a variety of 26" bikes. My skills have eroded considerably and my body can't handle much crashing these days, so take this with a grain of salt, but I feel they've got some advantages, especially for bigger folks. I know that on chunky wheel-trapping type terrain I'm faster, and on my personal bikes, total wheelbase is pretty comparable to a 26" setup. Chainstays are 440mm (or about 17.5"), and I can manual/wheelie about as well as I ever could on a 26er. Which is not very well, of course.

    Alex Morgan has done some serious racing (at a pretty high level) on 29" wheels for years, as well. He might chime in if he's still around and using MTBR.

    The rim/tire/fork selection currently doesn't make it possible to compare apples to apples, but I'm guessing we'll see 29" wheels carve out a smallish niche in the light-duty DH/freeride section of the market over the next few years. Most folks won't want one, and I don't see 26" wheels going away. That said, with decent tires, rims, and forks, they do (as folks have pointed out) make things easier in some situations. They also cause problems in some situations, of course, so like many things, it's rider and terrain dependent.

    Ride what you love. Love what you ride. Regardless of wheel size.

    Thank you, Walt! An intelligent, well spoken (and properly spelled! ) response from someone with plenty of real-world experience in the actual issue being discussed! I can't believe this actually happened on the internet!
    Much better than "I only ridding 29er on trail and Glory on DH, I no ekspereince with DH race on 29 but I spew opiniens lyke thay arr fakts"...

    Nah, not really that much, but the guy spewed off like an idiotic know-it-all, and his spelling really was unbelievably bad, so I couldn't help it... It's kinda like if a fat chick is rude, what's the easiest way to insult her? Doesn't mean you hate fat people...

    Not gonna see 29'ers become common on the dh market because of packaging. In the back, finding space for the seat tube, suspension linkage larger tire, mud clearance and wheel travel means either hughnormous chainstays or compromised design. In the front... well, forks price per unit to produce goes down much more quickly with volume than with frames, and there just aren't enough pro-29er tall dh'ers around to warrant tooling up.

    How about this? 36 inches of something or other.

    not sure what mast configurations have to do with biking to be honest.

    It's amazing how close-minded and conservative DH guys are.
    I thought you guys were risk takers, but you seem afraid of anything new.
    Just a bunch of knee-jerk reactions, "me no like, big wheels bad!"
    Like Walt said, a 29er DH bike will be better in some areas and worse in others.
    If I could afford it and they actually existed (the 2951 is only a prototype and there are no forks other than the Dorado), I would replace my Bullit with a 29er freeride bike without any hesitation.

    The same advantages that I get in XC/AM riding with my 29ers would apply in downhill - the bigger wheel would roll through the chunky stuff better and would hold it's momentum better. The only disadvantage I've experienced is slower acceleration. That isn't much of a problem when doing downhill runs. And contrary to know-nothing assertions, the bigger wheel is no problem when airborne - I can jump my 29ers just as well as I can the Bullit. I just can't land them in a rock pile as safely since they don't have the travel, slack angle or burly wheels of the Bullit. Those things are not 29er related.

    If all of the arguments against 29ers are correct, why aren't you guys riding on 24 inch wheels? Or why not 20" BMX wheels? Who says 26" is the optimum size?

    Naturally that begs the question why bikes have sort of fallen on the 26" wheel size.

    There were bigger wheels, and there are smaller wheels, so maybe, and I'm just throwing this out there, just maybe its a good compromise...

    Right now my 26" bike works pretty damn well, so you saying we don't take risks etc, then I ask you why you think I should change something I really see no problem with?

    Like someone else said, its not just a yeah big wheels roll over stuff better but the whole package, how do you fit all the right bits in there and still get the right geo/travel etc?

    Right now my frame is pretty tight with 26" wheels, adding another 1.5" radius would mean a lot of other compromises.

    Yes big wheels roll over bumps better, so maybe for rocks etc you don't need 8-10" of travel, but big wheels do not help absorb landing impacts, so less travel no matter what wheel size is worse.

    On top of that, generally in the wheel world, you want to REDUCE mass, rotating inertia etc etc, so no matter how you slice it, a 29" DH worthy tire is going to be heavier than a 26" tire and that weight, as well as the rim etc is further out from the axle, ie double whammy on your rotational inertia right there. This might be ok for slowly rolling over rough stuff in xc conditions, but DH bikes go faster, rotational inertia increases with speed, as do the gyroscopic forces, eventually it will become difficult to turn the thing.

    As someone said, its physics.
