6 Years ago, I wrote an article with the title, “I was wrong! 29ers just aren’t as much fun!” (click here to read the article) and I caught A LOT of flack for it.
Which is funny because at the time it was true. After 6-7 months of testing a bike I thought was going to be my dream bike (a specialized EVO 29er with a 68˚ head angle, one of the slackest head 29ers at the time), I found 29ers to not be as much fun as my 26″.
My Evo 29er
Times change though! I thought a 68˚ head angle was slack for a 29er, and at the time it was. My current 29er has a 64.5˚ head angle. Add that to a 25mm longer teach measurement and that makes it the first bike that has ever fit me!
This bike is designed with a steep 76˚ seat tube angle and a magic button on the handlebar that locks out the rear suspension and further steepens the seat tube angle by another 1.5˚ for climbing. This puts my hips much further forward, so they are above the bottom bracket when seated and climbing (instead of over the rear axle). So now I don’t have to hinge forward as far to keep the front wheel planted. It also allows me to pedal down instead of forward. On my first ride, it felt like my power increased by 20% overnight!
Did I mention it has 170mm of travel and descends like a downhill bike? Yet, it weighs under 31 pounds (for an XL 29er with heavy tires) and climbs like a cross country bike.
It’s a great time to be a mountain biker.
Ultra Modern Geometry , 170mm of travel and it weighs less than 30 pounds!
For me, at 6’3″ and as a rider whose stoke is going fast and riding steep chunky trails, it is way more fun than a 26″ wheeled bike and a bit more fun than a 27.5″ wheeled bike.
For riders whose goal it is to cover a lot of ground fast and/or efficiently, 29ers are hard to beat. This article is more for mountain bikers who like steep and technically challenging trails.
However, if I were shorter and/or one of those creative riders who like to pop off all the sniper hits on the trail, I don’t think it would be as much fun as 27.5” or 27.5” in the rear with a 29” upfront (which I think will become the new standard for riders between 5’6″ and 5’11”).
My 29er is not super nimble, it’s fast and actually corners really well, but I would not call it playful. Also, on sharp angle changes, where the trail suddenly goes from flat to super steep, my rear tire rubs on my shorts and I have a 35″ inseam!
Riders with legs a few inches shorter than mine might find a 29er quite cumbersome. This can be seen in World Cup downhill racing where most, if not all riders under 5’10”, are riding either 27.5” or 27.5″ in the tear and a 29″ tire
So, like my previous article, it still depends on what you find fun (raw speed or playfulness) and your height, to decide what wheel size (or sizes) is right for you.
The good news is that there are more great, safer and fun bikes on the market than ever! Though they aren’t cheap.
On a side note, for riders shorter than 5’5″ I feel (for the same reasons listed above) a bike designed with a 26″ rear wheel and 27.5” front wheel, would be the ticket. These bikes may not be out for a year or so, as no one currently makes this bike but if the 27.5”/29” catches on, some smart person will make a 26”/27.5” for shorter riders eventually.
Also, maybe even for riders my height and taller the reverse mullet (27.5″ in the rear and 29″ front tire) might turn out to be the best design. I haven’t tried it yet so who knows?
I hope this has helped you. Something to remember when testing bikes: Change feels weird. If you like your current bike, any bike you test that has differences (different handlebar height, handlebar width or handlebar roll, different stem length, different tire size, different reach measurement, different head or seat tube angle, etc.) will feel weird.
Weird isn’t always bad, it’s often better, but it may take a week of riding or more for it to kick in.
That is why l test bikes for months before writing about them.

Most Fun and Confidence Inspiring Bike for You!
Great article as always. I like a hardtail 29’r and I live here in beautiful Asheville, NC (of which you are very familiar) and ride in the gnarly Pisgah NF. Looking for a bike that climbs well (cause I can always make up it’s descending drawbacks as a hardtail by the skills I’ve learned reading your stuff). What should I be looking for in terms of angles?
Thanks, Adam! Glad to hear my articles have helped your riding. Well, IMHO there are three bikes with nearly perfect angles ( 64-65 head tube angle, 76-77 seat tube and proper reach measurements (500-515 for an XL, 470-485 for a large and so on down in 30mm increments) they are, my awesome Scott Ransom, the amazing looking new Enduro from Specialized and the Capra from YT. On the darn close (just which the head angle was a degree slacker) and one of the best bikes for the money is the Kona process 153. I will have a blog on the perfect geometry (currently, things might get even better) and the traits of the most confidence-inspiring and fun bikes soon.
Cheers,

DOOOD! I’ve been thinking a 27.5 rear 29er front is the way to go! I’m 5’9 and haVe experimented with this over the past few years. Good to see someone noticing this idea! Love your system man! Thanks for all you do!
Hi Billy, you are welcome! This really seems like the next big thing. 27.5 wheels are stronger, accelerate faster, and give you more clearance (than 29) while 29″ tires roll over things better and have better traction. The key with this set up (at your height and especially for riders shorter than you) is to run flat bars. The only problem with 29er fronts is it puts the cockpit way up there, causing many riders to ride too upright when standing and descending! IF you go this route please let us know what you think after a month or so of riding a reverse mullet.
Cheers,
Gene
Great read Gene, thanks! I went to an Intense ACV with the 27.5+ and love most thinks about this bike other than the lower bottom bracket and resulting pedal strikes versus my old Janis 650B2. I received a set of 29er carbons with it which o never used because I’d have to give up the wider footprint of the 2.8’s on my 27.5+. But I did start to wonder about putting a 29er on front with a 2.5 or 2.6 tire. I’m 5’11”, 190# primarily riding Junction and Fruita. Thoughts? And thanks!
So after double reconstructive knee and right shoulder surgeries (car accident), I’ve not ridden in over 2 years and now making it part of my therapy for recovery (tried the PT stuff… do what you know and love and your body will respond!) To get back on the trails. I sold my vintage Gary Fisher Sugar 26″ (many upgrades over 17+ years) for a pre-owned Trek Superfly Carbon 29er. I’m 5’11” and must say I feel like I’m riding not just a completely different bike, but just a different machine period! It’s going to take a while to get back into it, but wow, the efficiency and speed on a 29er just after 1 week is amazing! I miss the handling of my 26, but after readying your article, going to keep at it as now I know there’s light at the end of the tunnel. Thanks for the write up. Any pointers on te upgrade?
