The one thing that most people dislike about bike helmets is how big they look. Even with the generous vents, it often adds up to a bowl around a head. For those who want something sleeker, the Bell Sweep R might well be the ticket. It sits close to the head and seems to keep the curve of the helmeted head human not android-like. We can't prove that it's smaller than the Giro Atmos, but when we see it on a noggin from afar, it seems streamlined and natural. The Sweep R still has plenty of vents, 20 of them that flow into channels that go around your noggin, and that's more than enough to keep you cool. And when observing the helmet off the head it's easy to see through it. And if that isn't enough, take comfort in the fact that both the Credit Agricole and CSC Pro Tour teams wear them in competition and out year 'round; it's been worn to yellow jerseys, pink jerseys, victory at Roubaix and Amstel.

The Bell Sweep R has 20 channeled vents. The microshell is fused to the protective foam that is itself surrounding an internal reinforcing cage. The GPS fit system is an easy-peezy dial to snug the secondary retention system against your head. Available in 3 colors. Weight is 9.9 ounces.
