I have an older pair of 404's that are still great, but old and used. I just upgraded my road bike to Campy 12-speed and wanted to get a new set of 404's for racing. The new set does not disappoint! With the newer aerodynamic design they are very quick and climb like mountain goats. The old set is still fast but the new 404's are freaky fast! After riding them for a few hundred miles I reluctantly took them off because they will be used primarily for racing. The old set reminds me how great racing will be!
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!
