Of all the aero helmets we’ve tried lately, the TT2 is the one that kept our heads the coolest. The large channels and vents do a decent job of keeping the heat down without sacrificing aerodynamics.
It’s easy to put on in a hurry and there’s no visor, which increases drag slightly, but it’s another reason why it slips on so quickly.
A long, sweeping tail and close-fitting sides help keep the drag down to a minimum.
