There is an auction on eBay for a disk wheel, not sure if it is a HED or a Zipp, but it is 650c. It is an older disk with a 7 speed freewheel. The following is a quote from the seller.
" There are two small holes that got poked thru the wheel by another wheel’s axle by accident, but those are covered now by a bit of tape. Those holes are small enough that they don’t compromise the strength of the wheel one bit."
Is the wheel’s strength and integrity compromised??
It is probably a HED as the carbon is soft get holes fairly easily. Mine had a couple of small holes and they didnt affect it in any way that I could tell, I just covered them with black tape.

What material provides the support on a disk wheel?? The carbon skin or a honeycomb core?
So, a couple of holes isn’t that big of a deal?
Hard to say. Depends what the rest of the disc is like. A couple of pinholes shouldn’t make a huge difference but older carbon discs sometimes go “soft” in the same area as where holes develop.
Also consider that for $65 you can get a custom cut disc cover from wheelbuilder.com as an equally cheap alternative to an old disc.
Yeah, but will it make that cool rumbling sound ??
JK !!!
Seriously though, there is a buy it now price for $110.00 and it is tubular, which I plan to race on. Plus I want to use “old” parts, it’ll be more clear when I post pics of the bike. Right now I do not have any tubular wheels to use for a cover.
Also, I don’t think that these are “pinholes”, he said a puncture was made by another bike’s axle.
I wouldnt worry about a hole made by an axle. My HED was used for $180 and already had some dents and a crop circle, but scored a hole when I was warming up prior to a TT on a windy day and the wind blew it over onto a trainer and punctured it. I also put another hole in when trying to force on an extra tight tubular with a screwdriver (stupid I know). I rode it for two years with no more than some tape over the holes.
I just recently sealed it with some lightweight filler and it is off to get a custom paint scheme and should look like new.

The hed’s have no core, they are hollow and extremely easy to dent. You can dent a hed by thinking about it.
If it is a HED with spokes in it, no problem. If it is a Zipp with just a carbon skin, it could mean that the wheel could fail. I am not a carbon expert, but HED wheels have spokes in them and I believe that the carbon is superfluous.

Earlier HED discs were structural carbon (no spokes, no nomex core). The ones today are spoked wheels with a non structural carbon fairing.
You just responded to a thread that is more than 13 years old.
Sorry if that is inappropriate here. Some people get upset when a new thread is started on an old topic. Others get upset when an old thread is revived.
