I just got the carbon fiber version of the Ch aero cover, but I can’t figure out how to get it all bolted together. I have a Mavic Open Pro Rim, and when the cover is centered over the wheel, the circumference of the cover overlaps about a millimeter of the braking surface (it’s not flush). At first I figured that fastening the bolts would squeeze the cover making it fit flush to the wheel, but that isn’t the case. I can get a couple of the bolts to get together, but that spreads the other parts of the cover too far apart. I’m hoping someone that has installed one before can help me get it figured out. I’ll gladly send pictures to anyone to help clarify. I’d be really grateful to anyone that can help me get it installed, I’d love to be able to get it installed for the weekend.
Sometimes those covers need to be trimmed. Or, move your brakepads up a bit (if you can). I’ve not been around the carbon fiber one, so I can’t advise on how you might go about trimming it. The plastic ones are easy to trim.
Would trimming the edge make the two sides come together easier? That’s more of a problem now than the cover blocking the braking surface.

Hmmm…maybe, maybe not. If the screws (the plastic ones?) aren’t reaching, you need to call CH and talk it over. Yes, if you tighten them too much, the edge buckles and you ruin the aerodynamics. Did you buy it from CH, or from a dealer?
Sounds to me like your wheel has too much dish or the CH cover was designed without enough dish. Maybe you should take a look at the two sides off of the wheel and see if one has more than the other. Switching sides may help.

I installed all the bolts loosely, then tightened each of them a little at a time. I also bought longer aluminum
hardware from Home Depot. By the way, where did you buy your carbon wheel cover ?? I’ve been looking for
one myself.
Good luck. Shawn
With longer bolts it installs somewhat better, but I’m still having issues with too much of the braking surface being covered. My patience is running low, and I might just have it installed by a shop. Another option is just going ahead and getting a Renn 575 and getting rid of the disc cover. PM me if you are interested.
I’m sure you probably just need to trim it. THe standard CH cover often needs trimming to fit different wheels, I’m not sure why the carbon one would be any different. If in doubt, you might shoot an email to Richard at Wheelbuilder, I’m sure he’d trim it for you and if not, would probably tell you the best way to do it.
Assuming your rim has a v-shaped profile, trimming it will help to make it seat itself closer to the tip of the V. This should bring both sides closer together and you should be able to attach it with the same bolts you currently have, eliminate the over-hang of the disc cover to the rim, and remove the portion of the disc cover contacting the brakes. At least this worked well with my plastic one on my Velomax Circuits.
I don’t know how the Carbon version is, but counter-intuitively, I had to trim all of the foam inner lining off the outer edge of my cover to get a real flush fit against my rim.
Where did you get the carbon cover?
