has anyone tried these?

Link?

Counting this post, I've spent thirty seconds getting the link:
http://www.crankbrothers.com/directsets.php

It's the OP's responsibility to post the link if they want feedback.

No, I haven't tried one.

It's also pretty damned easy to get this one. Hell, I don't even think a link is necessary, since if someone is using one, they know exactly what it is and where to get info.

OP, depending on which one you're talking about, I've used the C version. Not much difference between these and the cane creek one's. I think they are the same design really. Worked fine for the short time I had it. I sold the bike before I put too many miles on it. They look nice, but you can get the same quality much cheaper.

OP, I asked for a link because I had experience in them, but only one model. I wanted to give you an accurate feedback so it's best to ask specifically which one you want feedback on.
