It looks like the CAADX has QR hubs in the rear. Can anyone confirm? The Topstone is 12mm thru axle front and rear.
The top tube and chainstays meet lower on the Topstone. The CAADX has much less sloped top tube and this will make it stiffer, no? Or is that just for carrying the bike during CX races?
The Topstone says it is dropper post ready. I don't know what that entails. Can someone explain how that is different?

Yeah, QR rear for the CAADX.
The more level top tube of the CAADX is better for carrying the bike in cyclocross races. The sloping top tube of the Topstone exposes more seatpost, so theoretically the additional flex from that should make it a bit smoother ride. No idea if that's enough to matter. The sloping top tube also gives more standover clearance which might matter to someone.
I think the "dropper post ready" is just them pointing out that the frame is designed for internal cable routing for a dropper seatpost.
