The twenty-one speed Schwinn World 21 is the base offering in this line of casual bikes. One of the features emphasized by Schwinn in promotion is the Shimano Revo twist gear shifter, which is designed to deliver effortless shifting. The lightweight aluminum frame of this bike has geometry that is made for comfort over long rides. The SR Suntour M3000 alloy fork will aid in a bump-free ride over easy terrain. A rear rack gives you the ability to transport. This model is a step down from the next-in-line World 24 model in that the World 24 has twenty-four speeds, a higher quality Suntour NEX fork, and double wall rims.
