Schwinn DSB Hybrid Bike, 700c wheels, 21 speeds, men's frame, grey. This is a bike that can't make up its mind. Today it is a road bike, tomorrow you can take it on the trail, and the next day it's ideal for a ride with the family. Any way you slice it, the 700c DSB by Schwinn is the perfect bike for everyday riding. It has an aluminum dual sport frame with a front suspension fork to smooth out any bumps, while 21-speed Shimano EZ-Fire Trigger shifters and a Shimano rear derailleur make for smooth and easy shifting. There are dual disc brakes that provide excellent stopping power in even dusty or wet conditions, and the alloy double wall rims are strong and lightweight for added stability. A great bike value that you will enjoy riding for years to come. Like all Schwinn bicycles, the DSB comes with a limited lifetime warranty for as long as you own it.
