I don’t have any skin in this game, but they are awesome. I run them on my Aeroad and am very pleased (rim brake). Running them with same tires and very supple. Fit wheels like a glove. Obviously, since it’s a system... I’m very hesitant to swap them for GP’s 4/5ks.

And the brakes sound sweet against the Mavic surface.

I’ve fantasized about buying these for my next bike that I don’t even have yet, but I’m poor.

Hope that helps.
