I don’t use tubes but damn, this CS tire is giving me fits. Has anybody out there managed to get them set up tubeless? I’ve gotten them to inflate but there is (obviously) some air leaking somewhere and they are flat in a few hours. I’m trying with an H3+ disc and zipp FC 808. All I need to know is…is it possible? Thanks 
You need tubeless compatible wheels.
The hed wheel is tubeless compatible but I’ve never had much trouble in the past getting tubeless to work on “regular” rims. I’ve used the hutchinson fusion, the “heavy duty” version of the fusion (whatever that was way back in the day), the schwalbe ironman tubeless, the schwalbe pro one, the compass bon jon pass, and probably a few more in there I can’t remember. As for wheels most have gone on the original dura ace road wheel (with the crossed spokes), the (really old!) stock wheel on the bridgstone RB-1 (ritchey rim of some type), the hed h3, the pacenti sl 23 (?). You know, a variety of tires and “regular” rims all no problem. Not one single flat and no blow-offs or anything else scary.
The CS…has me pulling what’s left of my hair out 
I’ve had zero problems. HED Jet6+, Flo 9 CC, and Flo CC disc.
Putting one vote in for not attempting it on the Zipp wheel.
Haven’t had any personal experience, but in one review I read it was mentioned that it took more than the usual amount of sealant to get the Corsa Speed TLR to hold air. Like 50-60 cc total.
Shouldn’t be an issue on the HED. Another vote from me for not trying tubeless on the 808.
50-60cc? That might be part of it…I’m trying to squeak by with 20-25cc.
What is it about the 808 that you guys don’t like with tubeless?
Has anybody out there managed to get them set up tubeless?
Quite easily, actually. I was pretty shocked, but they were simple to get on the rim and set up easily with Orange Seal. Of course, I am using tubeless compatible wheels, which helps just a little

I think that depends on what you mean by “hold air.” I always do an initial inflation with no sealant at all just to snap the bead in place to make it easier to put the sealant in. And it holds air just fine in the sense that I could probably go ride with it for a while. It might just lose pressure faster than I’d want. I haven’t tested leaving it with no sealant to actually measure the rate of pressure loss without sealant.
How much sealant did it take?

I’m not a weight weenie, so I used like 1 3/4 ounces. Probably overkill, but whatever.

Because they’re not designed to be run tubeless. You might get away with it. That doesn’t mean it’s safe.

My Dash Cycle disc, which is tubeless ready, took 2 minutes to install and fully inflate with 30 cc of Stan’s race sealant. It stays fully inflated for 6-7 days before it starts to get noticeably soft. On the other hand, I fought my 808 FC for hours. I knew right from the beginning it would be a problem since it was so easy to put on. In fact I would say it was loose on that rim.
Well…OK, let me ask about plan b then…hed jet 6+ vs. hed jet 6 plus black is the only difference the brake track or is the black faster?And a followup, zipp v1 FC 808 vs. hed jet 9+ is there any difference in crosswind handling? The 808 isn’t “bad” for me but it isn’t nearly as easy as a “regular” wheel.

Dr. Fastskiguy,
Mine are set up tubeless on non-tubeless rims and have worked fine. They hold air WAY better than any latex tube as well. I wouldn’t bother using anything less than the full 2 oz of sealant when setting them up.
I’m pretty busy with the cyclocross stuff this weekend. Do you want to borrow my wheels for a quick test? They are the Hadron 800+ with 11-28 11 speed cassette. I still have the disc cover on the back, but that can come off in a minute since the freehub body pops off with two hex keys.

No aero difference between the Jet+ and the Jet+ black rims. I doubt you’d notice any difference in handling between an 808 and a Jet 9+. Once again, I’d advise against trying to run the 808 tubeless. I don’t think it would be safe to do so.

Not looking for an argument, just curious about the rational behind this statement. Non-tubeless specific rims are way harder to get tubeless tires on and off. Even with a catastrophic blowout, there’s not a tubeless specific (bead) road tire coming off the wheel any faster than a standard clincher. I haven’t had my hands on a Zipp an 808 long time. Is there something incredibly unique to the newer 808 that is different than a normal rim?
You would have to run CX type pressures for the bead to burp, so the shelf/bead lock seen on a lot of tubeless rims is really there to aid installation and keep the tire in place while it loses air. That’s one disadvantage I saw with my Corsas was that after letting them sit for a couple months, they lost all air, the tires came away from the sidewall (breaking the seal) and the sealant likely dried out.
I’ve run probably 98% of my road tubeless miles on the Schwalbe Pro Ones, while the other 2% have been on the Corsa Speed TLRs. The Corsa Speeds seem more porous than the Pro Ones, meaning they are both harder to initially set up (you really have to spin and bounce the wheels and make sure the sealant does its thing) and they deflate more quickly. With my Pro Ones, they will go from 80psi to 60psi in just two days, but after that, they deflate much more slowly. I can leave a wheel hanging for at least a month and the tire will still stay seated on the rim. With the Corsa Speeds, I would need to be much more attentive - I haven’t experimented with “time to bead unseating” but I did once leave wheels with the Corsa Speeds hanging for a few weeks and when I looked at the wheels, the tires had come unseated and the sealant had dried out.

The bead is held more firmly in place in a number of ways with a tubeless compatible rim. Probably most important is the “shelf” at the bottom. If you hit a pothole, or your air pressure is low, the bead can unseat on a standard rim. That can be bad. The better bead retention also gives you better shot at maintaining control during a blowout (vs. sliding around on the metal/carbon rim).

Same tires and experience here. My original Schwalbe Ones held air better and were incredibly strong. For the entire watt or watt and a half that they dropped going to the “Pro” ones, they lost a LOT of durability and pressure retention.
