As far as aero wheels are concerned, the new Hed Stinger 6 marks the start of a new era. After modeling the wheel, Hed made prototypes and spent a full 10 days in the wind tunnel to test and perfect it, and came out the other side with a brand new rim profile. This is not evolution, with just a few tweaks here and an extra millimeter there. It is more like when a comet killed the dinosaurs and paved the way for mammals. At 15º wind angle the new Stinger has 100g less drag than the ’08 model.
