Details

The leading edge of rim design.

The trend toward wider rims is perhaps the simplest trend to explain in all of cycling right now — more rubber on the ground equals more traction. Ibis’ 741 Carbon Wheels accomplish this in a couple of ways. First and most obvious is the rims’ 35mm internal width. For comparison, a Stan’s Flow rim from a couple years ago had a wide-for-its-time internal width of 25mm. This added width spreads the tire beads outward and allows the tire to take on a more U-shaped form, rather than the lightbulb-like shape we’re used to. That means more knobs on the ground, and with less work for the sidewalls to do, you can run them about 5psi lighter than you normally would.

The second key to the rims’ success is their lack of a bead hook — right, lack of a bead hook. No snapping in place sound when you mount tires, just a nice settling in. This makes the wide rim both light and strong, since the shapes are simpler, and therefore less carbon fiber has to be used. We haven’t burped one yet. At the core of the rear wheel is a DT Swiss 350 hub —a workhorse from a company that makes nothing but workhorses.

From ENVE to 741s

  • Familiarity: I've used it several times

I recently built up a new bike, Santa Cruz nomad. On my Niner RIP 9 RDO I was running the ENVE M60's. I loved my ENVE's best upgrade I have ever done. With this new build I had heard a lot about these wheels and with a price difference I decided to give them a go. Best decision I have made. These wheels are awesome and with the 35mm hookless width, they were easy to mount. Ibis def has my vote with these wheels. You can also pick custom color decals to match your ride.You will read a lot of threads about what tires to run on such I wide profile. I am using a Maxxis Ardent 2.4 - Not sure how I like this tire on these wheels. The climbing ability seems to be not as good as on a narrower 25mm rim. On the Front I am running a Minion DHR (yes a rear tire on the Front) love the rolling resistance and the grip. Thinking about switching out the rear for another one of these.

Stiff and Wide

    Ran a set of these on my HD3 last year and was very happy with the decision. 2.3 High Roller II in the rear and minion DHR in the front. The carbon rides noticeably stiffer than my previous aluminum rims, much more predictable when pointing it through the rough stuff. As far as the width goes, it definitely made for a different ride. You can just see it, the tire looks much fatter on a set of these rims. I was running these at 18/20 psi without any issues. The result was a super tacky ride that kept you confident railing berms at mach-10.

    Wider is better!

    • Familiarity: I've used it several times

    Just got these for my SB5c. I was worried that 35mm internal might be too wide especially with no real lighter tires in the 2.3-2.8 width range. I mounted Maxxis DHF 2.3 and DHRII 2.3 front/rear on and so far they seem to be working well and retains a rounded profile instead of a square profile that happens when you slap on a too small of a width tire. I definitely love the more muted, planted feel, and notice the increased traction that they provide. The DT Swiss 54POE is also fantastic. I have upgraded my star ratchet on my previous wheel set and have had no issues with them for over a year. I expect same quality and durability from these as well!

    I have had the Chinese carbon light bicycle 30mm internal rims in the past and these feel similar to them. Overall I highly recommend these if prefer getting an inexpensive (for carbon) no frills wheelset! If you want to save more money (Maybe a few bills and in sacrifice for warranty) go the Chinese Carbon route with a custom build.

    Wider is better!

    So Glad I Bought These!

    • Familiarity: I've put it through the wringer

    Great set of wheels! It wasn't easy to get the maxxis tires on them but I'm very happy with this purchase! Thought about getting the ENVE but I don't like the internal nipples on the ENVE wheels. PITA to true them. Very confidence inspiring wheels! You'll feel like to can smash into anything!

    So Glad I Bought These!

    say yes to fatties!

    • Familiarity: I've used it several times

    Light, stiff, and so far…Burly. I’ve primarily ridden 26” Flows for the better part of the last decade, and



    this is the first time I can feel virtually no discernable flex from my wheels.



    The price for a solid set of carbon rims is nice a definitely worth the upgrade if you are on the fence.



    They pair very well on Ibis HD3 or Santa Cruz 5010 with schwalbe hans dampf tires.

    Grips and Rips

    • Familiarity: I've put it through the wringer

    My 741s weighed in at 1680g with rims strip and valves. Tough to beat ofr sub $1500 wheel set. The wide rim provides a noticable larger contact patch. My 2.2 Conti measures more like a 2.35 on the rear. I've been playing with air pressure around 20pis for a 140lb rider. A larger coworker of mine had some sidewall issues and lower air pressures, so it will vary by rider (like any wheel). Stiffness isn't an issue.

    ENVE is Envious

    • Familiarity: I've used it once or twice and have initial impressions

    I had a set of ENVE m60's just prior to these. Coming from ENVE's I was pretty hesitant, but these didn't skip a beat. Noticeably better in the corners and railed just as hard everywhere else. Very happy with them!

    Excellent Product!

    • Familiarity: I've put it through the wringer

    Coming from Stan's Arch, these new Ibis wheels are simply amazing! No noticeable flex in the wheels (very stiff), reduced rotational mass.....feels very light on it's feet. My legs aren't getting fatigued as easily.

    This is factually wrong on all counts: The stock Arch EX 27.5 wheelset is 1630g - 100g BELOW Ibis's claimed weight of 1730g for the 741. Most of that additional mass is at the rim.
    Stiffer components also convey more shock to the body, resulting in greater fatigue.
    There are benefits to a wide wheelset like the 741 (traction), but the areas you point out are in fact the major DRAWBACKS of this wheel vs. a lighter conventional aluminum wheel.
