Aerodynamic Innovations
Wind tunnel testing in our state-of-the-art facilities demonstrated that 16-spoke wheels provide the best aerodynamic performance. In fact, use of 16-spoke wheels slashed a full minute off a 1-hour ride at 48 kilometers per hour.
Wind tunnel tests in top-of-the-line facilities
A series of tests were used to gauge forward air resistance and the effects of crosswinds.
Comparison between 16 and 32 spokes
Compared to a 32-spoke wheel, the 16-spoke system slashed a full minute off a 1-hour ride at 48 kilometers per hour.
Aero-type spokes
SHIMANO’S aero-type spokes employ an elliptical rather than round cross-section for improved aerodynamic performance.
