Hi first of all sorry for the poor pics but since I'm abroad my phone is the best option to shoot some pics of the problem.
Story: in november together with my new s3 I also bought a pair of 20/24 45 mm enve clinchers. Although at first I was far from impressed by the finishing qualitiy of the rims I decided to have them build by a reputable dutch wheelbuilder (sapim spokes and dt hubs)
I put 22 mm veloflex carbon clinchers and vredestein inner tubes on ( inflated to 7 bar)
Since april this years I used them on approx. Seven rides on flat roads. I really like their stiffness what I dislike is the grabby braking which isn't a problem on flat roads but I wouldn't use them on descends since my confidence would suffer.
Since april i tried three different brakepads (enve, swisstop black prince and reynolds cryo) but no improvement so far
At the last ride I found the brakewall of the rear rim is moving out causing a bump in the braking
This specific point is near the point where the rim is joined together and a reinforcement spot on the inside with small holes and what looks like a hair crack
Needless to say I'm far from impressed and for safety won't ride these anymore.
I allready own two pair of enve tubulars an a pair of meilensteins and all are trouble free. At 90 kg I'm not that light but I brake short (don't ride my brakes) 80% front and for climbing I use alloys.
At the moment can't think of anything I did wrong. Does anybody experience the same or know of a bad batch of these rim ( have to say some china rims come at a better finishing standard)
Will contact enve later this week since the dutch distributor unfortunatly went out of business
