The deeper the rim, the more aerodynamic they are and the faster you go - when riding at any speed. The faster you go the more speed you gain because aerodynamics play a larger part of your speed. Where I live in San Luis Obispo CA, there is almost always wind and if you are riding into a head wind you need to figure that wind speed into your speed calculation. The downside of carbon wheels is they weigh more than a smaller profile (carbon wheel) and they are more affected by side winds. But the side wind issue has been somewhat mitigated by the bullet type profile of these. You also need carbon specific brake pads and they typically don't last as long as regular brake pads. So that you live with.

Tubeless
These wheels can be set up to go tubelss with the Stan's system and with the use of a tubeless specific tire. The tubeless specific tire is vital because they use a kevlar (aramid) bead that will not stretch. Using a regular tire risks a blowout - which on the front can be extremely dangerous.
