Jamis' lightweight and durable aluminum XR.20 frame is easier to pedal than steel and features tapered and ovalized tubing to optimize frame strength and durability while offering the cool looks today's young riders appreciate. A six-speed drivetrain is enough for any youngster to learn how to shift and master. It's also enough gearing to get around the neighborhood or park comfortably, which is why it has just one single chain ring in front: to simplify shifting. A double-sided chain guard keeps the chain in place and clothes and legs out of the chain's way. There's a protective derailleur guard attached to the rear of the frame to protect the rear derailleur from knocks, keeping it in adjustment longer for greater safety and control. A full alloy parts package -- including seat post, stem cap, crank arms, seat post clamp, brakes and rims reduces total bike weight and adds value. The XR.20's XC saddle offers lots of high quality padding for comfort and control, with a narrow nose so that legs can pedal freely without chafing.
