I've had the Cure 24 50mm standard weight for a few weeks now. They are on a gravel bike (for now) and mounted with 30mm Contis.
They look, spin, and ride great at lower speed. I have found they become unstable when going at higher speeds (so mostly going downhill) when there is even a little bit of wind. It's not like a push sideways, more like fast unpredictable twitching in either direction, and I have to keep a firm grip on the bars. First deeper aero wheels for me, but I've never experienced anything like it with my 35mm deep alloy wheels or shallower wheels.
Any feedback from other Cure 24 riders?
