Bought this wheelset for gravel tubeless set up including DK200 which I've done 3 times now. These are supposed to be tough unbreakable per Enve - and while I haven't had wheel issues on gravel yet, getting something wider and lighter than my current set with the potential for lower risk of pinch flats is attractive. DK200 is tough enough without flats! These weighed in at 1296 grams on my scale without rim tape or valve stem installed (which Enve provides with the wheels) so under the advertised weight. I haven't had the chance to ride them on gravel, only with 38mm slicks on pavement so far, but look forward to trying them out - for now all I can say for performance is they spin up easy, perfectly true, and no noticeable flex. I did convert these to QR wheels with different end caps from DT Swiss (easy to do). I have no doubt they will live up to the Enve claims for durability when I do get them off road.
After breaking a second Campy Record Carbon post in the past 5 years and given that they're pretty much unattainable, I decided it would be okay to defile my full Campy Colnago and I took the dive and went for the Enve post. Excellent fit and finish and stealth aesthetic. I've read complaints that it is difficult to adjust but I have to disagree completely. The dual wedge design is ingenious and all you need to do is get the seat tilt located approximately where you want it, tighten both wedge screws just enough to hold everything loosely together, and alternate tightening one wedge and then the other a little at a time to dial in the precise seat angle you want. No crawling around under the saddle to access bolts you can't see and can only wrench 14 turn at a time. Very well designed. I can't say I feel any difference in ride quality as it was a carbon to carbon swap. However, I also installed Enve Bar and Stem, replacing old school ITM aluminum and WOW! Huge difference in rigidity and ride feel with the carbon cockpit. Expensive kit but seems to be worth it.
