    I believe the reason is this is very dependent on rider weight, style, terrain and tire you use. Some will have a minimum of 20 and some at 30 psi. So they don't state a number. If you saw this 25 psi number somewhere, let us know.

    Francois,

    I read that in an early product preview on another site. It seems to have been said by Roval wheel engineer Jeremy Thompson. I would paste the link, but don't know if that's a huge faux pas, especially considering the person I am corresponding in this reply

    They are XC wheels with a maximum rider weight...I wouldn't use them as a free ride wheel but suspect they will stand up to a couple of seasons of XC racing...

    How would these be for 100 mile endurance racing

    I currently have a Santa Cruz Highball Carbon with Stans Crest/Hope 2s and I was thinking of building up a lighter set of Crest 240s with sapim xrays and dt 240s. Do you know how much weight the tubeless kit for the Rovals adds?

    Thanks!

    Specialized categorizes these wheels as XC rather than Trail. Are they too fragile for moderate trail riding?

    Here's the quote about the minimum tyre pressure for the Specialized Control Carbon 29 rims:

    The big news on the dirt is the introduction of the new Control Carbon 29. It brings the lightweight and stiffness of carbon rims down a price peg, to just $1,200. But price is just the beginning…they’re introducing an entirely new rim shape. Or, rather, a very old rim shape.

    Back in the day, rims were originally rolled steel and didn’t have bead hooks. With the advent of extruded alloy rims, they could easily put the hook on the rim as insurance against the wild variations in tire manufacturing. With tire tolerances more exact nowadays, Specialized found that they didn’t actually need the hook.

    Thompson says no one’s rolled a tire off yet, but they do have a 25psi recommended minimum for all of their carbon rims. The tire bead in compression (ie. when inflated) pops into place, and the Kevlar or carbon beads used in good quality modern tires won’t stretch at all, so it can’t expand to the point where it’ll slip off."
    BikeRumor.com

    2013 Specialized Wheels & Tires – Aero & Disc Road, Budget Carbon 29er MTB & More! - Bike Rumor

    The Specialized website states that there's a rider weight limit of 240lb (108kg) for the wheels but doesn't list any tyre pressure recommendations. With carbon rims there's usually a maximum tyre pressure rating also which would be useful to know.

    Max pressure is printed on the rims. Says do not inflate past 45 psi.

    Just received my set and the build quality is amazing compared to my chinese carbon rims.

    I'm getting 1600-1610 grams with 142 axle conversion and 15mm front caps.

    With quick release caps 1670.

    Mine came with 20mm caps as well.

    I'm sure it will hit the target weight without caps.

    According to Bikeradar.com, Control carbon rear hub is come from DT which has the same internals as DT 240s and DT 350 have. Thus, the hub should be compatible with DT Swiss' XX1 freehub.
    "Specialized has chimed in to say their Control Race, Control Trail and Traverse wheels are compatible with DT Swiss’ XX1 Driver Body since they use DT’s hub internals."

    Some things have been hinted at but to my knowledge not officially addressed.

    First - These Carbon Control wheels only come in the standard 12x142/135mm (adapters included) rear hub. The higher end SL models are available in 142+ and reg. 135/142mm flavors. 142+ setups are not compatible with standard 12x142 dropouts due to chain line differences.

    Second - The internals of the rear hub are from the DT 240/350 hubs (rear hub parts are interchangeable). So the DT Swiss XX1 cassette body is compatible.

    Third - Tire pressures are limited officially to 25-45 psi. Over inflating the tires could cause problems (pic of one guy inflating to over 100 psi).

    Fourth - The reason they didn't include the bead hook is because the rims are cheaper to produce without it. That's why (at least one of the reasons) they are less then the SL models (same hubs).

    I just received these wheels but due all the snow in northern Utah I haven't ridden them yet. Mine weighed in at 1610 grams with 12x142 rear axle and 15mm front though axle end caps installed with tubeless strips and valves. The rim strips are also removable/reusable (A first that I'm aware of).

    Not the first set of Carbon wheels they've put out, so what's to wonder? Research how they've handle past claims and you have your answer.

    Agreed. In my experience Specialized is more than fair from a CS/ warrantee standpoint. This is one of the reasons I would choose Specialized (I don't currently own a specialized but have had many in the past).

    These came with the new snap on tubeless strip, right? Not tape? I had to send my Control SL off to the service center and it came back with the snap on strip instead of tape. Wondering how this even works without actually sealing the rim, and how well. Is the strip wide enough that the tire bead sits on top of it and creates a seal between the strip and the tire, such that the rim itself doesn't need sealing? I went ahead and tried it with just the strip last night, and got it to air up but had leakage around the valve stem. Tightened it enough (by hand) that it seemed to quit leaking, we will see how the air pressure is when I get home today though. Just looking for long term experience from others, does the strip hold air well or should I go with tried and true Stan's tape?

    If you look through the cheap Chinese carbon rim thread, plenty of people are using the bonty strip with really good results. I can't imagine the ones you got would be much different.

    Well I finally had the time to throw some tires on these wheels. I set them up tubless with 2013 Rocket Rons Tubless EVO tires. I had a problem with the rim strip and valve stem on the front wheel. It would not seal up and leaked air from the valve stem area. I took the tire off and noticed that the rim strip was not aligned with the hole for the stem, so it was a quick fix.

    Other than that these were the easiest wheels I have ever set up tubeless. The tires seated at 40 PSI and so far are still holding air. I was surprised and impressed. Usually it takes me multiple attempts and removing the valve core to get a tire to inflate.

    Mine have been holding air great with the new strip, once I got the valve stem sealed up. I think I like tape better for that reason, it's stuck down around the valve hole and not gonna move, so the valve stem can seal it better it seems.

    Yea, a maximum rider weight of 240lbs!!

    I'd be willing to bet most riders will get a LOT more than a couple seasons out of these wheels. While I understand the no-hook bead is new to carbon wheels, I've seen nothing but very positive testing & feedback so far, and one of the stated advantages of no-hook bead is better impact durability due to a stronger carbon layup and added material vs bead hook models?

    Fourth - The reason they didn't include the bead hook is because the rims are cheaper to produce without it. That's why (at least one of the reasons) they are less then the SL models (same hubs).
    I spoke directly to a DT Swiss Rep yesterday and he was very helpful in describing the differences of the Roval carbon wheels.

    First off, it's ONLY the rear wheels that come with DT hub internals. The Control SL comes with 240 internals, while the Control model comes with 350 internals. The main difference between 240/350 internals are "slightly" better bearings in the 240, with a bit more internal machining to save weight without affecting strength. The Star Ratchet assembly is exactly the same! He also said for 2013 Specy will use all DT Revolution spokes (no more Aerolites), so for the rear wheel, the full weight difference is in the hub and rim.

    The front wheels of both models are apparently exactly the same hubs (not DT), so the ONLY difference is the rim itself.

    I'm still debating between the Control and Control SL models, but if the no-hook bead seals as well as they claim, AND it also adds strength for better impact resistance, it's hard to argue the bang-for-buck of the Control model? At msrp it really comes down to $500 for 130 grams weight savings with the SL ..... with everything else being very close to equal.

    Can anyone verify the front hub is convertible to 20mm? I understand the QR and 15mm caps are included, and assume if they work with 20mm you'd have to buy them separately. Any source for these?

    Mine have done nearly 1000km. No complaints. Still running the tyres the bike shipped with set up tubeless and have been perfect. Small leak on rear which is around the valve stem. I was thinking today that I've given them a right hammering over very rough hard conditions recently. The kind that shakes the fillings loose. I've also been ploughing into snow banks up to the height of the wheel when I've lost control and thinking thats proably not good for them. So far I think they are great and will take them in shortly and get them checked for roundness and straightness. Also going to swap to some Maxxis Ikons tubeless and see what happens soon.

    I'm not 100% sure, but the way I understand it ... only the "Trail" models of the Roval carbon wheels can adapt to a 20mm axle/hub. For the Carbon Control and Carbon Control SL I believe they use a smaller hub body, so 20mm doesn't work. Hopefully someone that knows for sure can follow with a definite answer?

    Why not call or email Specialized and ask instead of depending on someone you don't know on an internet forum?
    If you order based on a post here, what are you going to do if they don't convert?
    Get an email from Specialized saying they'll work and they don't, then you have a case to get your money back.

    According to the Specialized web site the Trail SL is 20mm capable:

    "•Front Hub: carbon/alloy body, 15/20mm thru-axle, and 24/28mm QR end cap options included"

    I'll be damned. A real person answered the phone. No go on 20mm for the Controls. Have to step up to the Trail version to get compatibility.

    I wonder I they got around Paul Lew's patent somehow or are licensing it. He was showing off Reynolds wheels with no bead hook a while ago.
