My only concern would be hand positions on the tops. It doesn't look like they'd be too comfortable for long climbs. Your hands would be pointing out putting your wrists at an awkward angle. But, I've never tried them so I can say for sure.

I have the Ritchey WCS OS bars on my LOOK and love them. Comfortable in every position and because of the longer drops there is plenty of clearance, for my forearms at least. I got them on sale for $47 shipped.
