Trekking feels better when you're on a lightweight aluminum frame, an excellent suspension fork, Shimano drivetrain components, and 24 speeds of climbing, top-end, and long distance options.
The Nashbar Trekking Bike brings together all the best of the cycling world. You get nice, big 700c wheels for efficiency, control, and obstacle clearing, but you also get slick tires that are skinnier than mountain bike tires so you can still assault roads and streets without losing all your energy in the tires. Plus the Suntour suspension fork means you're ready for a little off-road, curb hopping, and gravel/dirt path riding when it suits you.
The Shimano drivetrain gives you quick, efficient, and low-maintenance shifting...so you're never left skipping gears on a steep climb; and alloy riser bars and stem keep you more upright in the saddle so it's always comfortable on your joints and back.
