I'm using the 11 speed version on two of my bikes. Without checking my logs I'd say I've easily got over 3500 miles on the two sets with no problems. I didn't even have to tweak adjustments after initial use from cable stretch. They just keep working fine.

Black version:



Silver version:



I find all controls shift lightly and precisely. None of the "clunkiness" I get with the Mirage 9 speed setup on my Campione. The hoods are very comfortable and I like them better than any of my Shimano setups. The thumb levers are canted and very easy to use from both the top of the hoods and while in the drops. I think they are a real bargain. Performance wise I'd say Athena is easily on par with my lastest Ultegra 11 speed groupset.

If I could easily find full sets in silver still I'd be seriously thinking about either using it again on the De Rosa build or to upgrade my old Maillot Jaune.
