This is the quickest way to ruin your helmet’s aero performance and everybody does it, but here’s a free fix

When you remove your sunglasses, what do you do with them? 95% of us, including pro riders Valentin Paret-Peintre and Jan Tratnik, will slot them somewhere into the vents of our helmets, but I’m here to tell you that you shouldn’t. 

I’m just as guilty for it as the next person, and I get it. You’ve been riding for two hours, the heat of the day is becoming stifling, and despite the best cycling glasses weighing little more than a feather or two, you’re feeling claustrophobic behind their gargantuan lenses.
