Bought this to use with Campy EPS (11s) and non-Campy freehub wheel. Cassette range also outside Campy spec (11-28)...but it all works like a charm! Excellent, fast, no stumble shifting, only minor rear derailleur adjustment, 2 minutes, ready to ride. Durability with waxed chain TBD.
I cycle ~12K miles per year (and have for decades). Bike is Trek Madone with Campy EPS 11-spd drivetrain. Have used both Campy Record and Shimano Dura-Ace cassettes and chains. Most noticable, and much to my surprise, the PrestaCycle cassette is stiffer than the competition. Shifting is more precise (presumably because the spacing between cogs is precisely engineered), and contrary to some review claims, it is quiet. In short, the PrestaCycle cassette is an amazing piece of metallurgy and design that sets a new standard in a number of categories.I encourage you to try one.
I was hesitant to buy my first one because Shimano stuff is so good. These Prestacycle cassettes shift as well and are as quiet as the 11-34 from Shimano. I really like that they are one piece.
I am able to stay in the big chainring on all but the steepest grades. Kinda expensive but expect longer life.
