I purchased a 80mm stem to match my Enve bars.
Looks super slick and racey. The only issue is finding a light which has large diameter rubber straps to attach to these bars. One has to be creative. Overall I like this stem. Only negative is the $300+ price tag.
I have trouble finding 14 degree stems. Enve to the rescue. Beautifully made and the adjustment for the different rises is well done and worth having. BE SURE TO USE A TORQUE WRENCH. It seems to be a lot of torque to put on the top bolt but if you don't put the 10 NMeters (or whatever it says on the bolt) the bars will slip when smashing a pot holerailroad tracks etc. It's expensive but I would do it again if I had to.
This stem is very stiff and the adjustable angle shims are a really cool concept if you like to tinker with your fit. The overall package is a bit heavy, but when paired with the matching computer mount it's a very slick setup and worth the extra grams. Features nice simple unobtrusive graphics that should suit any build.
I used this stem as a cockpit redo for a team issue Trek carbon road bike. It makes for a very stable front end combined with some adjustability to fine tune ones fit. Very happy with this product.
Made a larger impact on the overall look of my bike then I anticipated. I was most interested in this stem because I like the -12 option since it makes this stem virtually horizontal.
