Why would somebody get a 29er?

Hi guys, I'm looking to get myself a mtn bike and have been reading about and trying to find as much information before I go out and make a decision. One thing that I haven't been able to find is why somebody would want a larger set of rims vers a smaller set? Can somebody shed some light on this for me?

Thanks!

bigger wheels means you roll over stuff easier, you go faster, the 29er is great for tall people, and it's sort of like extra suspension.

also, bigger wheels means bigger penis.

How do you go faster?

pros of bigger wheels = lower center of gravity, longer contact patch for increased traction, ability to roll over obstacles easier, feels softer (as noted above, almost like suspension)

cons of bigger wheels: heavier, wheels aren't as stiff, handling may not be as suitable in tight sections (largely depends on the bike)

oh, you mean with the 29er....the larger wheels means you cover more ground per pedal stroke, or something. larger wheels are faster than smaller wheels.

The 29er is six percent faster on uphill courses and three percent faster on cross-country courses than 26-inch mountain bikes, according to a study conducted by Pepperdine University.

That's a silly question. Larger wheels rotating at the same rate as smaller wheels will travel faster. The difference may not be noticeable to 99% of people who compare the two, but the difference is still technically there. Think large scale differences: You've got a pair of scooter wheels rotating at the same rate as a pair of monster truck wheels. Which would be moving faster?

What I've read so far is if you can't go over stuff with 26" wheels, you should get bigger wheels. So, to me that means if you're a hack get the 29er. If you're not a hack, get a 26er.

Bigger wheels giving you a lower center of gravity? Does not compute. Unless the BB is made of lead.

The fast guys that I've ridden with over the years are fast no matter what size wheel they ride. Technical ability and fitness will beat wheel size every time.

If you're using identical gears, then sure, you'll go further per revolution on a 29er, but you don't get it for free. The bigger wheel increases your gear inches, so its going to be harder to pedal the 29er if the gear ratios are the same. Its one reason we're seeing 36 tooth cogs out back now. You have to lower the gear ratios on a 29er to get the same overall gear inches as a 26er. On the opposite side, look at the huge gear ratios people use on folding bikes that have smaller wheels.

^---This... 29ers have yet to be able to break the laws of physics, though I hear it's in the works.

Like for the scooter/monster truck comparison, of course the monster truck will be traveling faster, but they also have blown 502 (or 572 or something) V8s over the 50cc weed-whacker engines...

In relation to the wheels' axles, a 29er's BB is lower than a 26er's BB. This creates a lower center of gravity and a more stable feel.

who needs fitness or ability? the wheels are 29 freakin inches!!!!! after everyone is used to the 29ers, the next cool thing will be 32 inchers. eventually you will have weak people who can't ride off a curb on 45 inch wheels cleaning everything!

My take on the 29er trend - if your fast and have mad skills on a 26" bike then you'll probably have close to the same (maybe a hair better, or worse - depending what your trails are like) on a 29er. If you suck on a 26" bike and you move to a 29er, you'll probably suck a little more or a little less - but you'll still suck.

I see. That would be when compared to their respective axles. When compared to each other?
But yeah I get how they could create a feel. Didn't know that, thanks.

Yea, I know - big secret. There is no magic bullet when it comes to riding a road bike, mountain bike or any bike - the more you ride, harder you ride, and the more you push the envelope (without going outside it) - both physically and mentally - the better you will become. Riding a bike with bigger wheels will make about the same difference in overall speed as taking/not taking a huge dump before a ride. There is a local trail here that has some technical features - I have ridden it with both a 26" and a 29" wheeled bike and cleaned it fine on each, I just prefer the 26" - but the thing that really gets my goat is when my skill is related to my bike - I have had people say they could clean a section if they had a bike like mine - totally disregarding the fact that I ride 14 hours + a week and have ridden that particular piece of trail over 100 times.
