With features like a lightweight aluminum frame, an advanced Shimano drivetrain, and efficient 700cc wheels, the Lamborghini Rapido is certain to remain a favorite weapon for novice cyclists looking to speed past the competition. The featured 21-speed Shimano drivetrain was designed with shifting efficiency and durability in mind. For added ease of control, the bicycle's twist grip shifters are mounted just to the inside of the traditional brake levers. Due to the close proximity of the brake levers and shifters, riders have quick access to braking and shifting without moving their hands too far--an ideal feature for added safety and convenience. To help tackle those steep hills, the Rapido comes complete with a triple front crank set, a feature that gives the rider seven incredibly low gears. For increased rider comfort, the bicycle comes complete with a soft cork wrapped handlebar, a comfy custom designed Lamborghini saddle, and an adjustable quill stem--a feature that allows you to lower and raise the stem height according to the rider's needs.
