Bontrager Aeolus 7 D3 Clincher
The draw: Smooth-riding wind cheating system
When it comes to aerodynamics, the wheel starts with the tire. Bontrager created the R4 Aero tire specifically to match the Bontrager Aeolus D3 clincher wheels to reduce drag. A wind tunnel test conducted by a rival wheel maker proved it to be a very effective combination. Ride quality is extremely forgiving, although slightly less snappy and responsive under all-out sprinting than some others.
