Schwinn's Frontier is perfect for getting out and exploring the frontier, or anywhere else you want to roam! Its lightweight aluminum frame and robust steel fork are great for cruising along dirt roads in the country or dodging potholes in the city. You get a crisp-shifting SunTour/Shimano 21-speed drivetrain for conquering the climbs, powerful linear-pull brakes for control on the way back down and a fine bar, stem, seatpost and seat from Schwinn, too.
