Are these really compatible with 6800 cranks? The 6800 doesn't have that one curved attachment point with all four attachment points being the same.

I got the Sub-Compact Oval Rings but these are similar so I felt adding a review would be relevant. So far I've been vary pleased with them. First of all, they look really good - of course that's personal opinion, but 5 stars there. Be sure to get the Road Bolt Covers additionally for a clean transition from the beveled crankarm to the outer ring. Sadly those don't work with the subcompact rings so if we're considering those I'd dock a star.
But how do they work? I found after bolting the oval rings to my bike that the shape wasn't very noticeable. However switching back to a bike with a round ring definitely is. These do tend to smooth out my pedaling stroke, especially when I'm tired and it starts to get choppy. I have no complaints at all about the timing. Whether it makes climbing easier is hard to say, I haven't noticed, but I don't usually track my ride data. On oval rings I've used in the past I've noticed they've thrown off my rhythm on long out of the saddle climbs, I have yet to experience that with these but don't have much climbing on them yet.
Shifting has been decent. It does take some fine tuning of the front derailleur (and I have to make a couple more adjustments) and I'm coming from a single chainring so that's already a hassle, but they shift between rings when I want them to.
Oval rings are definitely worth switching to and that's especially noticeable when you try round rings again where I found a lack of smoothness which I had grown to love with these rings. Now that Absolute Black makes these for most modern cranks, give it a try!
