Love the product. Use them mainly for Triathlon races with aero wheels. A little confusing at first on the website with regards to Kit. Thought I had ordered a kit of different sizes. Instead, they come multiple in a pack of the same size. So had to buy multiple packages to get extenders needed for different size rims. Now I have a bunch of extras I probably won't ever use. They will go into my parts bag I take to every event in case someone else needs something.
All I can say is good things about this handlebar. Feels great in the drops and grips good on flat top for climbs. Paired with the Zipp Service Course SL Stem... you can't go wrong. Didn't notice any flexing. Atheistically... Beyond Black looks killer!
The Zipp Service Course SL Stem (in Beyond Black) is my personal favorite when lusting for aluminum. Super stiff, lightweight, and dependable. AND... it looks damn good!
I've ridden these wheels on road and gravel. They roll well and seem to be best suited for wider, tubeless tires (I am using 30mm Schwalbe's). Mounting is easy relative to other tubeless rims.
