Specialized Decibel Helmet ($170):
You got the stylin' ride, you got snazzy, functional bike apparel. And now you need to top off your mountain-biking ensemble with one of the best brain frames money can buy. In our book that'd be the Decibel, a superb cranial guardian built with a carbon-fiber-reinforced inner matrix that not only improves crash safety but allows the helmet's top vents to open further for maximum air-conditioning. This wind-tunnel-tested design, billed by Specialized's marketing brain trust as 4th Dimension Cooling, uses a combo of front intake and rear exhaust vents that really do help your neurological motherboard run cool. And who hasn't uttered an en-route expletive while trying to adjust a cranky strap? With the Decibel's PRO Fit retention system, you can fine tune comfort on the fly—important for looser air-gulping uphill grinds or when it's time to cinch tight for those hairball downhills. And if you like to go streamlined roadie, the clip-on visor comes off in a wind-cheating second.
