Does this wheel (spinergy) look safe?
 

I'm thinking of trading a set of disc wheels for these:

Does that front wheel look a little chewed up? Will this damage affect the structural integrity of these wheels? They would look pretty sweet on a SS rigid I'm building up for urban/street and some light duty off road use.

a little? thats an understatement.

I wonder what's under the electrical tape?

My guess is broken carbon fiber. I wouldn't even think about using those, mainly because they are ugly.

I would not buy anything that is used, carbon, banged-up, AND could really hurt me if it breaks...

Good luck finding one person who likes Rev X wheels, even brand new.

Never trust someone when you are buying these types of wheels, unless it is unopened.

You couldn't pay me to ride those.

as a matter of interest.. what disc wheels are you interested in trading?

What I meant to say was disc brake wheels. They are Mavic disc hubs laced to Mavic UST tubeless rims. Based on the feedback you've given, I'll probably pass on the trade.

Well, I thought they would be interesting on my old pink and seafoam green c'dale. Oh well.

Hmmm, so maybe they are ok? Does anyone out there actually have first hand knowlege of CF wheel failure, or are we all just guessing here?

I dunno, I have a dozen or so bikes and I just wanted to do something different. The bike I am going to put them on has a really ugly paint scheme so I thought these would be cool in a tacky/fun kind of way. As long as they are safe I'm not really concerned with any other considerations.

With the wheels you saw that failed what was the cause? Was it in a crash or big drop or something, or a result of damage like this? I'm not going to be getting crazy with this thing, but I don't want the wheels to explode if I hit a pothole or curb, ya know? Honestly, I probably won't even ride it all that much.

I wouldn't touch those with a ten foot clown pole.

I wouldn't risk it, if a carbon blade breaks on a carbon bladed wheel like that it's toast, if a spoke breaks on a spoked wheel, it can be replaced.

If you are thinking abut them for the though of weight savings, for that kind of application, seeing how far metal has gone and the advances in rim building, the weight savings on a big piece of carbon(In this case pieces) like that is pretty much impractical. You're better off losing extra weight by either: riding more and get the motor(you) lighter or stronger, upgrading to lighter cranks/stem/handlebars/seatpost/saddle. If you want light on the cheapside, ditch all the gears, shifters, and deraillieurs, suspension fork and go rigid SS.

I know, there is absolutely no good reason for me to use those wheels on this particular project. I just want to. :)
