This is a little late but, seriously? Hackett rode bikes? So BA, one of my favourite athletes (I'm a swimmer mostly, just ride bikes on the side).

Oh, and no wonder he broke that spinergy, he's 6'6 and 210.

From here:

The picture attached shows exactly why you do not buy cheap, no-name, carbon frames. The owner of this bicycle was racing it when the steerer tube separated, he crashed in the middle of a race and slid on his face for about 8 feet. When he finally stopped sliding, he did not move. The ambulance was called, and in the time between crashing and the ambulance coming, the owner lost over 1 cup of blood from his face. He was rushed to the hospital to have emergency facial reconstruction on his cheek, and all of his team members decided to quit the race, or leave before they could race, to accompany him at the hospital. He will survive, but with lots of scars and road rash. This is a warning to everyone. Do not buy cheap carbon frames, because as you can see, you get what you pay for. To put it into perspective, this frame was built around 5/11/11, and it was raced 5/15/11, obviously this cant be from overuse.

Yeah, this. Also, Bontrager OEM stem on my Sawyer. Total crap, and replaced with a cheap Truvativ and all is well.

I don't have a picture of it, but my coworker who is a super-gnarshredder bent a Ritchey stem on this ridiculous carbon Jamis hardtail they gave him. His standing up and mashing actually twisted the stem so that the bars slant to the right about 10º. Not confidence-inspiring.

A buddy in Australia had a Giant frame break the same way in the middle of a race one day. He landed on his face and was pretty fucked up. Giant immediately replaced the bike and paid for all of his medical care and lost wages. He'd never crashed the frame prior, sometimes shit just breaks.

It's a carbon steerer break near the lowers, so could it have been a poorly tightened headset, and the damage over time just gave out then?

Fork failure, I can deal with as a concept. Steerer tube separating from rest of brand-new frame, that's a bit harder to stomach.

Good carbon is really good. What people don't know is the cheap no-name carbon is playing russian roulette. Is it just an extra from a run? Was it part of a rejected batch because of too many failures? Was it done on the side by the foreman using scrap carbon as a way to make extra money? YOU NEVER KNOW. Stuff that's from Giant or Speccy or whatever is QA'd to a much higher standard and is much safer.

/\ this. That's the whole point of that guy's post. While I'm sure there's some (or sometimes a lot) of markup on carbon from companies, there's a face and a name and liabilities behind it, giving them a whole lot more reason to care.

Yeah, exactly. I'm basically repeating what I've heard from Mike Lopez (this guy - http://bespokecycles.blogspot.com/2010/01/serottas-mike-lopez-interview.html - I've ridden MTB with him a dozen times or so) and Yamaguchi.

Did you guys all miss Aek's post about how his friend's Giant did the same thing? I mean, yeah, everyone knows that any part can fail at any point, and with a big company they'll probably pay your expenses as you heal, but I kinda think there's nothing that I'm doing on a bike that's affected enough by the weight advantage to justify the increased (albeit marginally) risk of maiming.

Ugh, I sound like Grant Petersen, don't I.

Everyone should also keep in mind when Vivalo lost it's NJS cert. when one of their forks failed during a race. Or when one of Tzu's rims "exploded".

Shit breaks sometimes.

If there is a rash of Chinese/Taiwanese carbon failing then we've got a problem, but one instance doesn't establish a pattern.

Buffalo Bill, how's your Chinese crabon faring?

This is all pretty much bullshit. I wouldn't buy through an ebay middleman, but everybody needs a reputation to trade when all the payments are via bank transfer. There's not even a way to use 'scrap carbon' that makes any sense at all — when you've paid $$$ to CNC huge blocks of 6061 into molds you don't fuck around with your investment.

The worst gyp you're going to get as a customer is heavier parts from worn molds.

The prices they sell for direct don't require them to do anything too crazy. Normally it would get marked up 2x by the manufacturer and then again by the retailer. Carbon ain't a special material when it comes to margins — Maxway will make you pretty much whatever 4130 frameset you want for ~$100 when you're buying a container full. Aluminum frames from Kinesis are even cheaper.

aek wrote:

Just dandy.

The real problem with that dude's frameset is that it was too uggo to live. Real Pinarellos are already heavy enough from the mechanically-pointless tube shaping — the clone is just gonna be heavier and shittier since they don't have to sell it as a nice-riding bike, just as a Chinarello for cheapskate dental professionals.

Way underestimated my speed going over a curb and murdered my rear rim. The flat I got was only because a brake pad was hitting the tire sidewall where it was furthest out of true right at the hit, it blew out in less than 10 wheel revolutions. The DS spoke at the impact is loose by a few mm even after bottoming out the nipple, and the adjoining ones are beginning to pull through the rim with ripples visible.

It was ridable after fixing the flat and releasing the brake with the spring tension cranked up, just really annoying with the hop in it. Still rode it 18 more miles that night, and another 16 this weekend. Had to gingerly spin up climbs so the spokes would STFU.

Thankfully I have two spare rims and a spare Racing Ralph, the joy of hoarding.

I could transcribe a few hours of conversations with one of the pioneers of carbon in cycling, along with Yamaguchi (who had to repair/build some of the first carbon frames in the Olympics), but the gist is carbon is suspended in a resin, and you can throw an awful lot of shitty stuff together in that resin and then hide it all with the top layer of pretty decorative carbon.

If you say that's bullshit, well fine, go ahead, but I'm relating the experience of people who know stuff first-hand. Hell, Lopez ran the stress-testing labs for Reynolds. He bought and broke hundreds of carbon parts of all manufacturers to test alongside his own stuff. He saw how things broke, and what they looked like inside after they broke.

Wow, one friend's Giant broke so they all suck just as bad as a no-name brand. Logic!

Seems like a lot of this shit is user error and undetected crash damage.

I have never owned a load-bearing crabon part but if and when I do I'm buying a torque wrench first.
