"Way too scary for me."

"Update: I note that Ebikeling is now indicating on its web site that it will install conversion kits for $125.00. Given the work involved, I think that's a fair price."

"I want to do the same one day. One local place whose website I often check out is Ebikeling, which carries a good inventory of do-it-yourself kits and has been around for some time now. I don't know if they do installation, but if not they…"

"Scratches on carbon fiber aren't a problem unless it gets through the top (protective) layer.  And a scratch that's goes through that layer is something that you're going to notice if you're riding or if you see it. I think…"

"Jim, you just don't know what you're talking about, and I'd have to agree with Doug that you seem to largely be repeating talking points that you've read on the internet. My career as an engineer (BSME Georgia Tech, 1998) has…"

"1. A steel bike can be damaged just by falling over but nothing is ever going to convince you of that so have fun there. 2. So wait, do they fail without warning or in a crash?  Because failure in a crash isn't a failure without…"

"So which specific statement that I made do you think are incorrect? It's amazing how indignant you fans of carbon fiber get.  I will tell you the specific statements you made that are incorrect:      1. It does not take…"

"How do you say you're old and can't adapt to the changing times without saying you're old and can't adjust to the changing times? This was a stupid post to start with and you are set to make it even dumber by just barfing up the…"

"Of course, any material can fail. But the ease of damaging carbon fiber, the particular ways in which it fails, and the difficulty in telling when it's going to fail make it an especially dangerous material for bicycles. A minor impact from a…"

"Comments of this type about "carbon fiber" are almost always uninformed, and this one is. Carbon fiber-reinforced plastics and other composite materials are simply a (family of) materials that one designs for just as with any other…"

"Very educational. I just assumed there was carbon fiber involved. I'll admit that I had no knowledge whatsoever that people are using 3d-printed titanium parts on bikes. Whichever, some exotic material failed really spectacularly."

"well now, more confusion, as this photo clearly shows the basebar in one piece. so i'm not sure what the material of the 'stem' that appears to have failed.."

"Except in this case it was  3D printed titanium."

"Maybe they factored in that Chicago spent at least $64 million on a single hugely localized project rather than spreading money all over the city to promote biking in general. Since those heady days when Chicago was being written up as a veritable…"

"Should be really nice!"
