    Do all wheels work with Disc brakes?

    I just bought a Canondale CAADX Ultegra Disc cross bike. I was thinking about looking into getting another set of wheels so that I can have a set of road slicks on one wheelset and knobie's on another set. I'm not sure what to look for as far as road wheels for this bike? Are wheels disc specific? If so, any recommendations on a set of disc specific wheels. I don't need the lightest in the world, but don't want something that is going to be heavier than the wheels that came on the bike. I'm a clyde, current weigh in at 220, so that is something to keep in mind also. Thanks for any advice\info.

    The hubs themselves are disc specific as I understand it.

    My wheels (Stallion build...28 spokes) are rated for 250 pounds. 1600~ grams for the set @ $1K~. Excellent bang for buck, the HED Ardennes.

    There are some disc specific rims but they really aren't needed unless you are looking to shave some weight by removing the brake track.

    Spacing should be the same. Disc brakes are becoming more common on road bikes due to use of carbon wheels and the carbon is not such a good braking surface. But for disc brakes road frames have to have the fork and non drive side stay re-enforced. This is a non issue for you since most high end cross bike frames are ready for them.

    A wheel (hub) is either for disc brakes, or it isn't.

    To convert a non-disc wheel to disc, you will need Gorilla glue and the really thick zip-ties, but even then it might not work

    if you take a close look at your disk brake hubs you'll see that the brake rotor is attached to it. rim brake hubs don't have any way to attach a rotor. that is difference.

    with respect to rims, a rim that does not have to serve as part of the braking system, as mentioned previously, can possibly be made lighter and of materials that are friction challenged.

    Timely thread actually.

    I am seriously considering developing a tubeless ready, full carbon, disc specific rim. I already spoke with the vendor and there are significant grams to be shaved that would basically offset the weight of a 140mm rotor.

    I have been looking for a reason to roll the dice on this.

    I think OP needs the basic answer: no all wheels are not compatible with disk brakes. To be used with disk brakes the wheels must have features (brackets) that allow mounting the disk rotors on the hubs. These are quite readily obvious upon examination of disk compatible wheel hubs.

    That's just it. That is really a 29er rim and not designed for CX or road. I was thinking of a rim that was really a Gran Fondo kind of rim that could also be used for XC.

    Colnago has a new tubular version of this but no one has committed to a clincher as far as I know.

    Having just got back into cycling 2 years ago, and with my first serious bike purchase only last November, it's stuff like this that makes me quite aware of how conservative the whole road bike mentality seems to be...Tubes being still so widespread in use for instance. Tubeless is leaps and bounds superior...and should be farther ahead in road application than it is currently. At least some major tire manufacturers are finally jumping on board...

    This, you need a hub that the disc can screw into. Like this:


    However, it appears that you can buy adapters. Never seen one of those in the wild before.

    Tubeless for road bikes is a bad idea. The only way that it benefits road cyclists is by preventing most punctures.

    I know...the horror of it! riding wouldn't be the same without the constant threat of annoying punctures.

    Schwalbe has even released what some are saying is one of the finest rolling tires to have come out in some time...it's tubeless as well.

    Yeah, but when you do get a flat, it is a royal pain to get that tire off and back on. You can ride 25mm tubeless at low pressure, or ride 28mm with tubes at the same pressure.

    lol, ok guy. You're the guy who think he got a great deal - $1k for a set of 1600g wheels anyone smarter who chooses a non-overpriced rim can build for $600.

    Yeah, HED rims suck. I don't do labor.

    You got anything better than that? Nothing but tumbleweed it seems...lmao

    Oops...my bad. Stalker potential. Any mention of tubeless and disc brakes gets yer chamois all wadded up in yer brain...

    So, go ahead and $ub$tantiate why HED Ardennes + pre-built wheels suck at $1K... being such an expert and all that.

    OP - no. Disc wheels and your frame have different hub dimensions. Your frame is a 135mm OLD rear end. You will need to use hubs that have been designed to run on QR mtb applications or specifically for CX. As for rims - as others have mentioned you can run anything you want. It being disc specific or not is a non-issue considering the extra weight involved with the rotors and hubs far outweighs any small gain in removing the braking surface on the rim.

    Tubeless discussion - As of now I have and will continue to advocate that tubeless applications perform great for mtb but not at all well for CX. Those who have them perform well are operating at a pressure that is well above what is normally run and achieved with a tubular. This doesn't matter for riding and racing between August and early December in many cases. It will not work for Nationals, worlds, big events that occur after Thanksgiving in the midwest or majority of the CX practicing world/Europe/NE.

    Simply put you run a tire at the pressure needed to perform and it will burp....at the worst moment...and you'll be running to the pits with a dripping bike on your shoulder. Seen it a lot.

    Road? meh. Tire technology hasn't been there so far. Biggest issue is that all sealants will attack the all tires over time. Not much of an issue on mtb - little more of an issue on road where the forces on the tire are substantially higher.

    In general : High air volume: low pressure (Mtb) works well. Low air volume:High pressure (Road) works well. Low air volume: Low pressure (Cross) is a ticking timebomb of burptastic proportions.

    As for the last comment on why HED Ardennes pre-builts suck at $1k....uh...because the same rim can be used with amazingly higher quality hubs like a Chris King R45 and still save you a few hundred on the retail price. That's why.

    As for specific examples on the pressures I am talking about for CX: in the same race where racers with tubulars are running 19psi, tubeless competitors are running 26-30psi. As high as 30% higher inflation than those running the 19.
