Unicorns. Rainbows.
I used them on my road bike and my tri bike for training and racing (tri only, no road races for me). I switched to a tubular 404/900 disc and they now live on my wife’s speed concept. Solid. Aluminum breaking surface. They look great (and sound fast). They are a little heavy - 1850g if I remember correctly - but that’s ok.
The only thing I would caution against is that they are rated for tires no wider than 23mm.
