Fat, but light.
The Ibis 941 Carbon Fiber 29in Wheelset is wide. Like, really wide. So wide, in fact, that a few years ago, it would have been nearly double the width of the popular rims of the time. So wide that it’ll make your tires wider by a tenth or two of an inch. In a world where tire performance is dramatically different between a 2.2 and 2.4in tire, this isn’t exactly small potatoes.
Ibis saw more and more folks running medium-wide rims (in the neighborhood of 25mm internal) and thought, well, maybe even wider would be even better. They made a few prototypes and settled on an internal width of 35mm. At 35mm, most tires retain their general shape as it pertains to tread pattern, but also benefit from the wider base, which provides more support to the sidewalls, and adds volume exponentially.
What’s it mean on the trail? Grip, and lots of it. That extra volume means a bigger contact patch, and the extra sidewall support means you can safely run lower pressures, which again increases the contact path. It won’t turn your 29er into a fatbike, but you’ll get a little taste of what extra rubber on the ground can do for anyone.

the timing of this is great. I was browsing and saw the opportunity. I bought this wheelset from Jenson. I tried to give a review to them but they never published it. Why you may ask? I'll let your figure it out. My opininion wasn't inflammatory just the truth.
I bought this wheelset in january 2015 with the impression from the company that it was the dt hub.
I tried the tires IBIS recommended and had they would not hold air. Twice I got stranded in the middle of the ride with flats. I took the wheel to a local shop and they recommended that I place gorilla tape multiple times about the wheel. I went through an entire bottle of stans and it finally held air. In the middle of the next ride 3 spokes just blew up. I told jenson they sent the wheel to IBIS and I was told the xtr derailleur was at fault. My derailleur was fine. I argued and they said tough - give us some money and will rebuild it. I spoke to two different online wheel makers and they told me the spokes were cheap especially for a 29 wheel. I rebuilt the rear with bladed spokes. It finally worked though the front broke two spokes over the next year. Oh my derailleur worked fine even after abusing it in Sedona twice
Maxxis finally made the dxr wide trail and I finally got a tire that fit. CHuck IBis recently commented on his appreciation for it. Two rides into my new tires the rear hub blew up. I found out JEnson sold me the cheap chinese hub that IBIS changed for the DT. The new hubs from IBIS are no longer DT hubs if that says anything.
I emailed IBIS and they gave me the DT hub but I have to rebuild the wheel again which they would not pay for. The guy in charge of warranty told me to swap the spokes from the driver side to the non driver and vise a versa. Guess what doesn't work. I had to buy 16 new spokes which IBis wouldnt pay for. I asked to converse with Chuck and I got Hans Heim the guy in charge of the wheel program. I told him my problem and he asked me what I wanted. For the 20 hours of my time I dealt with this nonsense I asked him for a new mojo at cost. He thought I was rude and said goodbye.
I've owned 5 IBIS bikes I think there great. This adventure into making wheels changes my opinion about their products. I still own Mavic wheels that are 12 years old and never been tuned. My recommendation is to buy a wheel from a company that makes wheels and buy a bike from a company that makes bikes. Quality is sacrificed otherwise and you don't need to be made a fool by a major bike company who only employs twenty people. Just remember that IBIS went belly up in the nineties.
was It finally held ai to after two rides leaving me with stranded in the middle of the ride when I went to my local shop and
GOAT IS GOOD
- Familiarity: I've put it through the wringer
Got these for my Ripley (wicked great bike if you’re in the market). In comparing to identical tires mounted on Stans Arch rims they add millimeters, not centimeters to the width but I do think there is a little more of a contact patch due to spreading the casing out. They have stayed true despite taking a beating on trails. Set up tubeless without the need of an air compressor. DT hub has its mild whirr when freewheeling but nothing like the pleasant cacophony of an I9 hub. These are my second 941s. First was the early version last year that had a no-name hub (some asian maker for ibis). I put those on a fully rigid bike with and they continue to hold up very well mounted with 3” rubber for dirt riding and bikepacking.
I got the santa cruz bantan X01 from you guys, size m with 27.5 . What mm size is the right IBIS whee for my bike?
Is this the price for a pair?
The price is for both wheels. These are 29" wheels. For your bike, you would need the 27.5" version: http://www.backcountry.com/ibis-741-27.5in-wheelset and be sure to select the "XD body" in the drop down menu. Feel free to contact me directly to place an order with discounted shipping.

What is the XD body?
Hey Doug W,
The XD driver body is for Sram 11 speed cassettes.
That is a hub body that is meant to work with Sram 11 speed cassettes only, due to their 10 tooth cog that won't fir a standard hub body.
If you have any other questions you can contact me at email@example.com
where can I get end caps for quick release for ibis 941
Hey Vladimir P,
Dt Swiss offers end caps for these hubs. You can get them from DT Swiss, or have a local bike shop get them for you.
