Campagnolo Zonda C17 vs Roval SLX 24 -- Rim Brake Wheelset Showdown
230 lbs puts a lot of stress on the bike and all of its parts, especially wheelsets. Riding experience of a lighter cyclist, say 150 lbs, is going to be very different from a heavier one, so I always take reviews with a grain of salt.
Here is my review on two wheelsets -- 2019 Campagnolo Zonda C17 and 2019 Roval SLX24 with DT Swiss 350 hubs. There is also a mention of Fulcrum Carbon Zero wheelset which my bike was originally equipped with.

Campagnolo Zondas are fast and smooth. It is easy to accelerate on them. They climb really well. However, they are a little bouncy, where they amplify bigger bumps and dips, which adds up into a strange "bobbing" feeling.
As a result, the saddle keeps delivering amplified hits and the ride feels hard. This is especially noticeable during longer rides, such as centuries. You definitely feel sore after mile 70-80.
These weehls don't accelerate as fast as Roval SLX 24s on moderate climbs. However, they feel a tiny bit smoother and well-controlled at moderate to steep downhills.
Roval SLX 24s are fast. While they were originally not as smooth as Zondas, they got better within 100 miles. I am not sure whether it was a process of breaking it in, but there is a definite difference.
Unlike Zondas, these wheels don't bob; they delivering a smoother and faster overall ride. These wheels climb better to the point you barely notice the climbs.
Fulcrum Racing Zero Disc Road carbon wheels came originally with this bike.
