I know girth is important…but really?
Hey there! Its EJ from Tampa. I did a clinic with you at Mulberry Gap this spring. After the clinic I came back and really tried to process all of the great coaching and begin to apply it. As always it is a work in progress but I am definitely seeing results as I am finding better and cleaner lines on my local trails that I had always struggled to keep my composure.
Anywho, recently read your article on your clinic with Curtis Keene and your tire selections. Great stuff! It was timely as I am in the final stages of pulling the trigger on a new ride. I hate to say, that I am pretty convinced to get a big wheeler. Since I am smitten with my current Ibis Mojo SL, I have decided to get the Ripley with the new Cane Creek DB Inline rear shock and Pike 140 front fork. Since you have ridden with me, you know I am not race oriented and really want a capable and fun trail bike. With that being said, my questions are:
1.) In your experience, would a rider of my ability notice a significant difference riding carbon hoops? For reference I currently ride 26″ I9 Torch Trail 24 spoke aluminum wheelset.
2.) Current trends with carbon wheels have the inner width up to 35mm. For 2.3 tires is this overkill? What rim width do you see as the sweet spot for a 29er trail bike?
Thanks in advance for any wisdom you share!
It’s great to hear from you.
The Ripley with a 140 fork is a weapon! A very efficient, shreddable, versatile weapon.
If you can swing it, definitely go for the carbon rims — especially on a 29er. I really love my Roval Traverse SL 29s. They are light and strong, and they’re smooth and stiff in the right ways. AND: One time a guy parked his Chevy truck on my rear wheel … and the wheel is perfect!
I think you’ll appreciate the lightness, especially since you’re coming from a light set of 26es.
Beyond the articles we’ve all read, I don’t have an informed opinion here. Wider does make sense. Curtis was riding the new Roval Traverse SL Fattie 29 wheels (30mm inner width), and the 2.3 tires looked good on them. I can see going to 35mm inner width without disaster.
Curtis has been on these wheels since Sea Otter, and they are still perfect. That’s crazy given the season he’s had all over the world; many enduro racers were destroying wheels in France.
Since you’re getting an Ibis, definitely check out the new Ibis wheels.
Thanks again for writing, and for our session together. That was super fun.
Know more. Have more fun!

I’m very interested in more info on wide rims and wide tires. My desired tire would be all about traction, traction, traction. I could care less about “speed” and “rolling resistance,” I just want the widest, chunkiest, fattest tire I can squeeze in my Fox Talas 34. Really hoping there will be wider tire choices for 27.5 coming out soon. Like a nice 2.6 or 2.75, or even 3″ if it would fit my fork. Much cheaper investment in traction than wide carbon rims, but I still have carbon fatties in the “want” list.
The other day I rode the lift at Winter Park, CO with Greg Herbold, DH world champ and MTB hall of famer. He was riding/testing some wide 26″ rims with 2.75″ Surly tires.
According to the Surly site — http://surlybikes.com/parts/wheels/dirt_wizard_26 — this setup yields an outer diameter of about 27.5 inches.
Thanks for the fast feedback. With the myriad of bike stuff and often lofty prices, it is assuring to get first hand reviews and opinions of those who are truly invested in making a rider’s experience better not just anonymous internet posters. Hats off to you!
Looks like carbon hoops it is….kids can figure out how to pay for their own college. 🙂
Ibis Ripley with carbon wheels and full XTR for Daddy, community college for the kids … 🙂
Wide rims like the Roval Fatties are definitely the way to go. They offer several great benefits I’ve discovered:
1. Lower Tire Pressures = insane traction
2. They track extremely well
4. Less likely for your tire to burp air
5. The ability to ride out even if you have a slow leak in your tire, because the tires hold their shape even at crazy low pressures.
Two points to keep an eye out with wide rims though:
1- will it fit your frame/ fork? (A wider rim will make your tire wider)
2- tire cross section/profile. A high volume tire with a round ‘crown’ will flatten out nicely on a fat rim, a narrower casing with flat crown will leave you without edge knobs on a fat rim.
