Wind tunnel tested at the San Diego Aero Space and Technology Center, the 2012 Bontrager Aeolus 5 D3 wheelset combines the all-around performance of their 50mm racing tubulars with the tire installation ease of a clincher. Featuring a deep profile of 50 millimeters with 27 millimeters at its widest point, Bontrager uses wider rim to improve the aerodynamics of the tire. The wider rounded rim keeps the air attached to the tire and rim shape longer, therefore producing less turbulence and drag with an end result being faster wheels on the road.
