    Well,yeah it will work... And there is more than enough space to do it. You can even buy a kit with 2mm threaded steel "bullets" made for doing exactly that. Less holes = more continuous fibers = stronger wheel. I will definitely do this on my next set.

    Magnetic fields aren't alter by non-ferrous metals (in general), so only the distance can have an impact on the strength of your magnet. And even more since carbon won't do anything to a magnetic field, you have nothing to worry about beside making sure you have a good magnet not to waste time.

    Apparently other people have ordered rims this way so there must be vertical room to flip the nipple and drop it through its hole. Can anyone dig up that cross section with all the measurements?

    I can provide this as well. I emailed Nancy about this yesterday night actually, and here is the discussion:

    Me: "Just one more question. Please see the attached diagram, where I'm asking for a measurement of something on the rim."
    Nancy: "Hello Christ, It is 8mm. Thanks, Nancy"

    8mm doesn't sound right to me. By process of elimination, you start with 22mm rim height - 8.5mm rim bed to bead top = 13.5mm possible. Then you subtract the lower rim wall thickness (which may be 4mm???), and I'm left with 9.5mm nipple well. Even if a 9.5mm well is accurate, that's not enough space to get nipples through the spoke hole, is it? Most nipples are 12-16mm length, so I'd like to hear how some got the nipples through those holes when the well is 8mm, possibly 9.5mm.

    I'm no engineer, but the angle you mention has to be adequate. The mattress can bend, the nipples and boxspring cannot. For a 12-16mm nipple, we'd need enough play in the angle to make up for 4-7mm of lost height. People with these wheels can confirm they're running the wheels with no spoke holes? Did you have to use shorter nipples than 14/16mm?

    Hi all, first post but been following this thread and the 29" rim thread. Like the idea of this, and as mentioned previously, fewer drilled holes also means fewer broken carbon fibres, which should give more rim strength?

    Was also wondering as many have mentioned the spoke holes are all drilled dead centre of the rim, resulting in the spoke nipples bending the spokes. What about receiving the rim undrilled, and drilling yourself? This would allow the holes to be drilled at the correct angle for the nipple/spoke angle. I believe that the result could be a stronger rim as the spoke holes would be staggered instead of in a straight line.

    Has anyone had the rim only drilled on the inside, and fed the nipples in through the valve hole? Seen a few posts of the idea, but not any feedback of weather it has been achieved, and with any success.

    Well, I guess that is settled... 8mm is the correct number. Guess it won't work after all. Also note the 3K layer inside- these are a UD finish rim with paint done by light-bicycle. So two facts checked in one post.

    I just sent Nancy an email asking if there's enough room to maneuver nipples into their holes without rim bed holes. She said they've made rims this way but I was more explicit this time asking if it had worked out for the wheel builders. I always use 12mm nipples so I'd expect to need 11mm vertical space.

    There is more than 8mm from other angles, that is just the minimum dimension under the U in the channel. I'm a little surprised by this. The rim is pretty thick, and the holes are very square, meaning the entry angle will have to be straight. I was sure it would work, and took it on faith from Nancy... but I bet she was referring to their deep-section road wheels, not the wide 26" wheels! Well, facepalm me for advocating the idea earlier. It just made so much sense... My next order will be through drilled as well.

    Phew, thank god I didn't order mine without rim bed holes. It is too bad though, as it would have been ideal for strength. I was skeptical about the nipples being able to "angle in." I'm a little confused on what you're showing in that pic though, are you actively measuring something or just showing the digital readout?

    I'm measuring an invisible spoke nipple... ha, just showing the DRO.

    From talking to Nancy it doesn't sound like 12mm nipples will work without rim bed holes but she claims to have made rims like that in 650b. I'm trying to find the 650b thread so ask if someone there did it and what nipples they used but can't find it, help?

    Might be something in these, but I don't recall that conversation...

    Wow there really is alot of information here.

    Ok i have some questions.

    Where do you order these from?
    Tubeless?
    Have they been breaking?

    Oh goodie i can't wait to get some haha!!
    Ride it like you won't get another chance.

    I did just see this one... Cheap Chinese carbon rim fail?

    I am about to pull the trigger on a set. I think I will just have them build with the Novatec hubs. I have a 2010 Specialized Enduro and will be getting another bike within a year. I was planning on ordering the 881/882 hubs, which I think should work fine. 20mm thru axle in the front and a QR 10x135 in the rear.

    Brian says these hubs won't fit my bike. What are the best Novatec hubs to put on these wheels? Going with the wider rims.

    Could you use something like is used to fish electrical wires through walls?
    Send it through the valve hole, then hook a string to it at the spoke hole. Pull that to the valve hole, attach your nipple and pull it to the spoke hole.

    Given clearance inside the rim for the nipple to make the turn into the spoke hole, of course.

    That's the problem, not e nouh vertical clearence to let the nipple make the turn into the hole. Getting it to that point is done with either strings or magnet/ bit of spoke/tweezers.

    Do you guys think they would be willing to actually make a third version, the 26" wide tubeless ready with no outside drilling, just so we could all have a stronger and easier to set up tubeless wheel ?

    I guess that if there is enough demand, they'll look into it.

    At your size, if you ride fast, you might want to reconsider King hubs. They're 100% reliable for 95% of riders, and 0% reliable for the rest of us.

    I've been following this thread, but decided I'd break these rims within a couple months. Oh well, I guess good, strong, reliable carbon rims are still a few years away. But I'm convinced they're coming. Sounds like we need something less stiff, but more resistant to cracking.

    Hey Folks,

    just a quick thank you for all the information here...
    here's my front wheel, 24hole (367g), Sapim CX-Ray straight pull, recycled SunRingle Charger Hubs.
