If you’ve ever rolled up to a road race or triathlon and had to “quickly” swap cassettes from a deep wheel to a shallow one because the wind picked up over night, the new Two Point Zero Phoenix Hub system is worth a look. Designed to make cassette and wheel swaps extremely fast and easy, the heart of the hub slides completely out of the shell and pops into a wheel prebuilt around a second shell. And with additional hub bodies and shells available separately, you could show up on race day with all the options to mix, match and suit the course and conditions perfectly.

The system is modular in other ways, too. Hub end caps are available for 130 and 135 road quick release, and the body has a Centerlock rotor mount designed into it. This lets you run it on rim or disc brake wheels. Need to convert to thru axle? No problem, hub bodies with 12×142 are coming, too.

The shell is what’s laced to the rim, uses a keyed hexagonal-ish internal shape to fix the hub body into it. Just slide it in, then tighten two lock nuts on the non-drive side with the included tool (shown in top image).

You can also use the system to have multiple cassettes at the ready. I’m thinking that might be a good option for cyclocross where a course could turn nasty (or freeze) overnight and you need something with a different range or big cog. All of the parts -body, shell, freehub body, tool, lock rings, end caps, etc.- are available separately so you can build up as many systems as you want. A kit with one hub body and two shells (so you can build up two rear wheels) retails for $749 with standard Japanese steel EZO bearings, with Kogel and CeramicSpeed upgrades available.

To set it up with disc brakes, simply use Centerlock rotors or a Centerlock to 6-bolt adapter. The hub shell on the right is the production version with cutouts to save weight. Complete hub weight is 400g, and the outer shell on its own is about 107g.

Inside is a 104-tooth drive ring with six three-toothed pawls, clocked for around 3.5º engagement. They’re available now for pre-order in 24, 28 and 32 hole options.

  1. This is the perfect answer to the question I never had…
    Swapping out a cassette is no slower than swapping out this system.
    I like the concept, but do not really see much this having much up take in the market. Regardless, more power to them for the concept.

  2. I’m having a hard time understanding how this is faster or better than just swapping cassettes on normal hubs/wheels. You have to remove 2 lockrings with a special tool; looks like you’d have to remove the rotor if using discs, transfer the drive mechanism to the other shell, reinstall the 2 lockrings with a special tool, and reinstall the rotor.
    How is that faster than removing a cassette from one hub and putting it on another? With tools you already have, and would need to remove and reinstall a centerlock rotor anyhow. Outer shells run $150, I’d bet you could put cassettes on your other wheels for that.

    Is there some other benefit here?

    • I’m with you; this doesn’t seem to be any easier than just swapping cassettes the old fashioned way.

      The only real benefit I could see is that if you have a disc brake bike and a rim brake bike, this system might allow you to use one set of wheels on both.

      • Maybe… I guess. First hub costs $750 with everything needed to make it work, second shell costs $150. So $900 total in hubs for your 2 wheels. Hard to believe you’re saving money there, $450 each would buy pretty nice hubs.

    • Hügi did that before they where aquired by DTswiss, DTSwiss still uses the very same design. Heck +25y later spareparts are still interchangeable.
      Campagnolo’s current hub design only requres two hex keys to accomplish the same – that design is only 20y old.

    • Yup have this feature on my Powertap costs about 50 bucks or so. Still don’t know whose swapping cassettes around this much assuming they don’t add elevation or grades to a race wind really shouldn’t impact cassette selection that much.

  3. I think the marketing folks are asleep at the wheel. The value isn’t the fact that you can quickly swap the cassette. The value is that you can have a wheel that can be used on a road bike, cross bike, gravel bike, even a mountain bike with different hub standards…. all by swapping the hub body.

    • Yeah, you can switch between different wheel spacings, but the way it looks now, you’ll have to redish your wheel when going between 130mm, 135/142, Boost, and Super Boost. They could have designed it so that you wouldn’t need to redish, but then that would leave a very weak wheel, because it would have to fit the lowest common denominator’s extreme dish.

      Okay, at least you can switch between different axle standards, but you can already do that with different endcaps.

      Also, the fit had better be really good, because otherwise you’ll feel the hub body and hub shell move in relation to each other. As you accelerate the body twists one way in the shell, but as you brake with your disc, it twists the other way. Maybe you won’t feel that little motion, but it seems like it’ll help loosen the retaining nut.

  4. So if I want the option of two different cassettes I would typically buy two cassettes and a tool. Now I’m supposed to buy two cassettes, two hub bodies, the cassette tool still plus another tool and the whole process takes the same number of steps? Way more practical.
    Also, 104 points of engagement might be too many for road applications. Take it from someone who uses I9 mountain hubs on a cross bike, the drag when coasting on that many points at road speeds is ridiculous.

  5. The only things I could think of this being useful for are:

    – multiple Cycloross tubies with different tubular tires glued on

    – multiple Road race-day wheelsets of different weights/depths

    – A 650b x 47-60mm tire technical gravel wheelset and 700c x 32-40mm allroad wheelset on the same bike, with a high end cassette.

    Running the same cassette/spacing for both wheelsets seems nice in terms of wear/skipping wheelswap adjustments.

    ….already doable with DT swiss hubs.

    ….to the author: completely useless for casette swaps, watchu on about.

  6. Some other options: Boyd Cycling and Ritchey offer hubs with tool-free freehub removal so you can swap cassettes easily. (Prowheelbuilder offers Boyd Cycling hubs as an option in their wheel building wizard thingie.)

  7. Initial thoughts: If the outer shells are inexpensive you could build up extra wheels without the larger expense of buying several complete hubs. (27.5+ and 29er set for same bike, summer and winter set for your fattie, studs…etc)You would still have a single point of failure, if the hub went all your wheels would be down. Could also be a problem in the future if they stop making these at some point.

  8. Thanks for the feedback everyone. The initial Phoenix system includes 2 hub shells along with tool, lock rings and inner hub. You can buy as many shells as you like to have a stockpile of wheels at your fingertips. Tri, road, gravel, cross! Disc or rim brakes, the Phoenix has you covered. If you need more information on this please shoot me an e-mail. Thanks again.

  9. Powertap needs to acquire this for their hub based power meters. It would be the most versatile and rugged PM out there. Pedal based PM are easy to swap between bikes but the Vector 3 have given me all kinds of trouble compared to my powertap G3 hub.
