Sometime in 2008. I don't think they have a specific date. The new carbon RaceFace cranks are created using a patented process that (RaceFace claims) can make any aluminum design into a carbon version. I'll believe it when I see it . . .

You can buy them in a 3 ring setup or a 1 ring setup. If you're running a 1x9 set up, get the single ring version w/ a non-ramped chainring.

yeah, that is always a concern. i don't think i will ever get enough hours in to subject my cranks to that kind of "damage"...

i don't know, i will think about it.

That sounds like a valid long-term durability test. You've convinced me!

Yes, see the picture above. That's a long term durability test.

In my experience aluminum is more impact resistant and abrasion resistant than carbon fiber/resin.

I don't consider "hitting the ends on rocks a couple of times" to be any kind of meaningful test of the long term durability of carbon cranks.

I wasn't defending xcracer's post.. I don't consider his experience with carbon cranks meaningful either.

I was talking about carbon cranks, and just curious if there is any evidence of carbon cranks failing due to repeated pedal smacks. It's certainly a valid concern, one I honestly hadn't thought of when I purchased mine.

gunga din-

Are those aluminum cranks pictured and you're imagining what would happen if they were carbon fiber, or are those actually carbon fiber cranks that have absorbed many rock smacks/hits and still doing fine? The reason I ask is because I touched one of my carbon crankarms down on the street and introduced a minor "bevel" and I'm extremely curious on the topic. Thanks a million for any and all feedback!

Race Face Next SL cranks are like $600~ and lighter than XTR cranks by like 5 ounces. Their already out but pretty sparse.
