Ahh, the Fourth of July: time for hot dogs, fireworks -- and gadgets.

This week, the Gadget Lab and Wired magazine crew are proud to give you a sneak preview of our best online review package yet, the 2008 Summer Test section.

This year, our reviews have a timely Olympic theme. We rounded up the coolest summer sports gear – everything from swim goggles to kayaks, and golf putters to cyclo-cross bikes. You need to know about the hottest cycling shades or data-driven watches as well? Hey, we've got you covered.

We've also put these reviews in a flashy new format that we think will make our reviews more accessible, easier to read and easier to browse than ever before.

Here's a taste of what you'll find inside: Our head-to-head comparison of three cyclo-cross bikes.

What do you think of the new reviews format? Check out our lineup of summer product reviews, then let us know in the comments below!
