nope, sorry. just ran across it on ******. Looks like he's on a track though?

my bikes look like that on the trainer to my eye. TT bikes are particularly flexy, I think.

Me too.

Michelin Power Competition is my next order to replace my Conti GP4000s.

anyone have experience with the aeronova carbon replicas found all over on ebay? how do they compare with the real deal?

I believe the real stuff is selling out of hong kong for $120 now (way cheaper than before but still kind of expensive). But the stuff coming out of China is $30.. Any difference there?

Also, how does the carbon version compare with the alloy version?

I would not take a chance on something like that.

How do you know that the $120 ones are real?

Didn't somebody here have a story about breaking one of the cheapo ebay knockoff 3T bars?

I'm interested in hearing stories or any feedback.

local carbon repair guy buys stuff like that, tests them, and sell them off. in his repairs though, I don't know if he's really selling a service or a piece of mind of just having something patched up. He repairs dropouts too, which makes me a little skeptical. for checking the carbon, all he does is tap the carbon to see if there are any imperfections, rides on them for a while, and sell them. not sure if that's really a good test though.

I know that bad quality carbon will not with stand the compression forces being exerted upon it by the stem. I've seen clamps make grooves in handlebar and seat posts not from over tightening, but from bad quality carbon.

just trying to get a better understanding of the craftsmanship that goes into these things.

I don't know whether the $120 ones are real. Looking at the reviews, it looks like they probably aren't.. don't know why I assumed they were legit...

Don't remember if I had posted about it before but I broke a Hylix-made (not no-name Chinese but who knows what's the difference?) Aeronova knockoff. They sent me a replacement but I'm definitely not going to put it on my bike.

where did it break and how did it break?

the part affects not just the owner but those who race with the owner. don't be a dirtbag and endanger others

How is it different than knock off Chinese carbon rims? And people ride those all the time

those dirtbags!

it's a moot point if this is the same or different from knock off carbon rims, because one can show that he would be doing something ethically dubious without relying on a comparison to knock off rims.

the facts regarding issue at hand is that the person who posted is cognizant of potential quality issues and the dangers that may result. If he were to go ahead with purchasing the knockoff knowing full well that there are QC issues, then i'd call that a dirtbag move. Doing so only because it's a cost saving measure makes it worse.

the problem with analogies and comparisons is that it draws attention away from the issue at hand, and often the fact patterns are not the same between the comparisons.

As a side issue, if I know someone who's considering a knockoff rim that has a history of failures, i'd exhort the person not to buy that knockoff rim. And if the person were to continue with the purchase knowing of the QC issues, then that would be a dirtbag move

Expecting a knockoff to be built to the same standard as the real deal seems misguided at best. Especially with things vital to your safety and the safety of others...seems worth the money IMO.

Cracked near the clamping area. Not 100% sure but I think it happened when I hit a pothole hard. It wasn't a catastrophic failure or anything though. I noticed the cracks perhaps only after a few rides of the suspected pothole hitting incident. As I said though, can't be sure.

friend of mine cracked his carbon rim at a spoke hole that he suspects came from a pot hole. But I think those are somewhat common. I recall doge citing that they go through wheels like crazy during the classics in europe. when you took it off, did the clamp sink into the handlebar? do you have pictures?

I'm not expecting the same quality. the knockoffs probably don't undergo the same stress tests that legit products go through. I'm just asking for empirical evidence.

fwiw, I've seen a felt carbon seat post develop grooves from regular clamping. they did a huge recall for it though. quality is relative. what's considered legit in the bicycling industry probably won't pass inspections in the aerospace industry. not everything comes out of taiwan is top notch. at the same time, not everything coming out of mainland is ****. I think there's a pretty large grey area.

I think most chinese carbon bike stuff is probably pretty decent (dengfu, hongfu, etc), but I also think that chinese carbon parts that are designed first and foremost as cheap knockoffs of real brands' gear are probably garbage.

that's a good point. no argument there. there's a fm099 out there that looks exactly like the venge (probably garbage). there's also the fm098 from dengfu, which I owned for a while (great bike) that was designed from scratch and everyone loves it (finishing wasn't that great though). but I just checked, and dengfu has a handlebar that looks really close to the aeronova, but the reach/drop are wayy higher. (it's called HB250)

wait, it might actually be the same.. they appear to make their reach/drop measurements differently

I wish there's a carbon fiber expert on here who can comment on the craftsmanship that's required to go into these components. I believe in the 80/20 rule, where you can put forth 20 percent of the effort and get 80% of the benefits and in this case, quality. I don't care if it's fake. I just want to understand the engineering and craftsmanship.

I'm on my third Praxis BB in less than 7k miles as of this morning. Their Turn Zayante crankset requires their proprietary BB, so I can't switch to another brand. There's a slightly different part number on this one, so maybe they recognized a problem and addressed it. If this one doesn't last longer, I'll replace the crankset with a Shimano and use a different brand BB.

I'm seriously considering making my Look 585 with a standard (68mm BSC) BB my primary bike again. I never had that problem with standard BBs.

Well, that's a bummer. I was hoping to read stuff about Praxis. My Wheels Mfg BB conversion is creaking and I've considered going over to Praxis for the added stability from the expanding collet.
