The monsters get even monsterer.

The Ibis 941 Wheelset already carved out its own place in the wheel world as the widest out there, which affords it a few notable benefits. How to make it better? Swap out the rear hub for some top-grade stuff, perhaps from hub masters DT Swiss, and your result is the Ibis 941 29-inch Wheelset with the DT Swiss 350 Rear Hub.

So what sets them apart? Width. Wheel manufacturers have slowly started to figure out that, on both dirt and pavement, going wider pays dividends. Wider internal rim widths (note: not simply a wider rim body) means the tire beads can sit farther apart, which means greater tire volume, which means that lower tire pressures can be run for greater traction and handling, because the tire is more free to deform and deflect around obstacles without drastically altering the path of the wheel's momentum. Ibis says you can run 4-6 less PSI of pressure, on average, with the 941s. Wider rims translate into a wider tire footprint, again boosting traction and increasing stability at the same time. A wider footprint also means that your tire fattens up relative to its labeled size; for example, a 2.2-inch tire can widen to the volume of a 2.3- or 2.4-inch tire, depending on the rims themselves, so you can run lighter tires without giving up capability or gnar-ability.

Now, take a closer look at all-mountain wheels these days and you'll find internal rim widths from 21-26mm. Ibis takes that average and gives it an "F." Witness the 941: thirty five millimeters. That is gigantic. That is tremendous stability. That is traction for days. But they must weigh a mega-ton, right? False. The 941's rims' carbon construction keeps weight down to an astounding 490 grams per hoop, totaling 1770g each, and coming from the company that raised legendary all-mountain machines like the Mojo and the Ripley, you know durability is a given.

Ibis also tested the gravy out of the best competitors' rims for comparison and found its new 941s to be anywhere from 50% to 300% stronger in various tests. Part of what made this possible was the hookless bead construction of the rims, which optimizes tubeless tire compatibility while strengthening the bead by replacing traditional musical note-shaped beads with stout rectangles of carbon. Spoke holes are reinforced by additional carbon to ensure strength, too. Ibis opted for traditional J-bend spokes (triple-butted: 2.2 - 1.5 - 2.0), and standard 7075 alloy spoke nipples, all available from your local bike shop in a very-worst-case scenario.

The Ibis 941 Wheelset is for 29-inch mountain bikes. Please be sure to check your frame's specs to be sure that it can accommodate the 941's very wide rims. Out of the box, the front wheel comes ready for a 15mm thru-axle, while the rear comes ready for a 12x142mm thru-axle. End caps are available separately to convert both wheels to quick-release compatibility. Running a 20mm thru-axle on the front wheel is not currently possible. The wheels will come with either a standard SRAM/Shimano HG freehub body or a SRAMXD freehub body.

be carefull

    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

    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 jehall@backcountry.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.

    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.
