Jamis produced the X-20 bike in 2010 and can be classified as a Youth bicycle.Jamis Youth X-20 can be found in a few colors, among these colors Black and White .
This bike is equiped with 20 x 1.95" CST ATB tires and Nickel-plated spoke wheel while the rims are manufactured by Alloy, 36-hole. Jamis equiped this exact model with Alloy Linear Pull brakes, alloy short reach levers braking system and Heavy Duty ATB with Nutted Axles hubs.
To guarantee the comfiest ride Jamis used 7005 aluminum material for the frame. ATB tapered high strength material is used on the handlebar of this X-20 to ensure the perfect handling while the stems are made of Jamis Threadless.
For the smoothest biking experience Forged Alloy with chainguard, 36 teeth is used on this bicycle linked to KMC HP20 chain that is easily replaceable as stated by Jamis, the whole system is connected to a high reliability Shimano RevoShift SL-RS35 gear shift levers.
