Is this supposed to be vindication for a bad choice? Note that the 38mm tubeless set is four times what you paid for your wheels. https://www.yoeleobike.com/ https://www.yoeleobike.com/disc-brak...-c38-road.html It also comes with DT hubs, making it a good value. The daily sale aluminum/carbon wheels with no-name hubs are still more than twice what you paid. https://www.yoeleobike.com/carbon-al...lset-50mm.html

Moreover, Yoeleo has made an effort to legitimize itself with a plausible web-presence, claimed UCI "approval" and other hallmarks of a legitimate business. We know nothing about your $250 FleaBay purchase. Who made your wheels that, by the way, exploded. The issue is not the fact they were manufactured in China. My Emonda SLR was made in China -- it just wasn't some POS knock-off with an unknown pedigree.

Tell us Jay - do you use carbon wheels? Or do you as seems to be normal here criticize other people's choices? You have already given us the idea that you live on the hill in a gated community and don't even pay any attention to the town you supposedly call home.

A have some Dura-Ace C35 carbon/aluminum but no pure carbon wheels which I think are a poor choice for a rim brake bike in a wet climate.

BTW, there are no gates in my community, although I do live on a hill -- along with most other people who live in close-in west Portland. I am solidly middle-class and so is my neighborhood -- and actually kind of ratty around the edges.

I see no footprint for Tom Kunich. No patents at the USPTO. No published scientific literature on LEXIS/Elsevier/Medline. No publications on Amazon.. Gawd, even I have stuff on Amazon (thankfully out of print). No public office. No professional associations. All of your claims about being the great scientist and engineer, there is no hint of your existence except your own internet forum posts. You are basically invisible, yet everyone else is an idiot. If you want to know about my professional and civic involvement, just Google me. These make me feel good: https://www.thestreettrust.org/2015/...e-1995-heroes/ https://www.huffingtonpost.com/rex-b...b_3861490.html You can even get a writing sample: https://www.cocklelegalbriefs.com/wp...df-Beattie.pdf Before being critical, Andre should understand that a cert petition is a peculiar type of writing unrelated to ordinary English prose.
So, Tom, feel free to post the links to your science and engineering achievements -- that you did not write.

Jay, if you've never had pure carbon wheels what would you know about their braking power? Mine have about the same and the brake pads are less effected by wet. In fact on the ride I went on Thursday it drizzled on me during rollers and I never even noticed any change in braking.

I have come to believe that perhaps disks are the way to go because carbon rims will mechanically last forever.

My son has pure carbon wheels, that's how. I've logged a lot of hours riding with my son up and down the canyons in the Wasatch Mountains and the usual local stuff. He complains about the price of brake pads, poor breaking in the wet and problems overheating on long downhills, of which he saw many riding for the University of Utah. Go Utes!

Are you saying that full CF rims brake as good as AL rims and don't get worse when it is wet? That is not my experience owning a set of Zipp wheels and Mavic Comete wheels. At best they brake half as good when dry and even worse when wet. I think I'm not the only one with that experience. I don't dare myself in the mountains with a full CF front wheel. They are aero wheels and I use them as such in time trials and trying to go fast on the flats. Thank god we have a lot of that here ;-)

It's not just braking ability, it's heat dissipation. The CF rims are
not going to last as long as aluminum rims mechanically, but they also
can fail more spectacularly due to heat. One CF rim brand did an
extensive test of the heat dissipation capability of different rims to
showcase their proprietary resin.
https://www.bikeradar.com/road/gear/article/alto-destroys-carbon-clinchers-in-braking-heat-test-51474/

"The issue with carbon clinchers is that rim braking generates heat,
and, when pushed to extremes, can cause the resin to soften, which can
lead to the rim bubbling or folding open. In worst-case scenarios, the
rim can fail enough that the tire can come off or the inner tube can
burst from the heat. Years ago, a few events like Levi's Gran Fondo in
California banned carbon clinchers after multiple incidents on steep,
winding descents. "

CF rim design has improved to deal with the heat issue, but they are still not optimal. It's a nice material for disc brake bikes. I don't doubt that there are some well made Chinese CF rims for reasonable prices, but I would be suspicious of a $250 complete rim-brake wheel set. IMO, the weight differential isn't that great either -- maybe 20g CF versus aluminum per rim. Shaping is nice for aero wheels, like Lou says.

Light stuff is faster. It IS about the bike to a degree, but I have learned that one can save money and be fast on a relatively heavy bike by choosing slower riding companions. My speed has skyrocketed after choosing to ride with the sick and disabled. Today, however, I'm riding in the rain with much faster riders, and after racking my knees skiing yesterday, a bike that weighed nothing could not save me from getting dumped on the climbs. If I only had carbon rims! I would have dominated!
