These came stock on a new Aethos and are 4cm too wide for me. I “test-rode” the bike with them on, inside, for under a mile, and I had to wiggle the brifters off and peel off the sticker, so that’s where the visual “wear” is from. Nice ergonomic-profile tops, but definitely still closer to round than aero. 123mm drop/75mm reach; compatible with 11-speed Di2 bar-end junction boxes, but there’s no hole behind the clamp for any stem-routed cables or anything like that. The 38cm version of these bars, I can say from experience, is incredibly plush — if you have an Aethos Expert or a new Aethos Comp and want to make it feel more like a higher-end bike, these’ll be perfect for you, but they’d be a nice upgrade to any road bike with a 31.8 stem clamp.
