I love, love, love this wheelset. I ride in flat/ hilly area. I was thinking about getting ENVE 3.4, but I am glad I bought 4.5. This wheelset is fast, stiff, and does really well in cross winds. Fast and stiff doesn�t usually translate to compliant or comfortable, but this wheel is 25mm internal and 32mm external, and it can hold large volume of air, which translates to lower tire pressure and comfort. I highly recommend this wheel to anyone that are looking for high performance wheelset.
This is by far the best set of wheels that I have used. They are super smooth when accelerating and the crosswinds hardly affect them if at all. The tubeless set up was very straight forward. Also, the freehub sound is very low key which I prefer over a loud one.
