The draw: Full-on aero shape
The Split is a hybrid between the longer tailed helmets popular five years ago and the recent trend toward rounded, shorter tails. The wings don’t play nicely with sunglasses and make it tricky to put on quickly in T1, especially for people with wider heads. Four massive channels under the brow suck air over the head and out the back of the helmet through an exhaust port, cooling effectively while traveling at high speed. Testers found it to be hot on long climbs. Three size options make finding the perfect fit easy.
