Diamondback Century Road Bike - 2016. The 2016 Diamondback Century Disc is intended for the long distance group rider, charity rider, Gran Fondo enthusiast, or anyone who just wants a serious road bike that doesn't push your body to the limits like a full-on race bike. It packs the added bonus of being equipped with disc brakes, giving you the best stopping power available on two wheels. The Century Disc is made from Diamondback's outstanding 7005 alloy, making it stiff, lightweight, and absolutely durable. The geometry of this bike is all about efficiency and endurance, and utilizes Diamondback's proprietary Enhanced Performance Geometry. It has the same performance characteristics as their road race bikes, thanks to its stiff, lightweight construction, but with a taller headtube and more relaxed fell that's easier on the back and neck. The alloy disc fork helps lighten things up, and is super stiff to give you increased confidence to dive into turns. Component wise, the bike is spec'ed with Shimano's excellent Sora 9-speed components. You'll get crisp, accurate shifting that will deliver incredible performance for mile after mile. Paired with a compact FSA Tempo 50/34t crankset, you'll have plenty of gears to complete even the most challenging rides in good time. Stopping is handled by a pair of Tektro Mira disc brake calipers. So, what's disc all about? Traditional road bikes stop using rim brakes, which can be a little iffy in wet weather, in descents, or on gravel roads. Disc brakes use a caliper that squeezes a metal rotor attached to the hub, much like a car, to give the rider more powerful stopping performance that isn't affected by weather. The results are amazing, and are set to revolutionize road riding. Finishing off the build is a bevy of components from Diamondback, including an alloy stem, handlebar, and seatpost, and the exceptionally comfy DBR Performance road saddle. The bike rolls on Equation SE Disc road wheels, which deliver improvements in durability, stability and speed--plus an IS 6-bolt disc hub with a 160mm rotor in the front and a 140mm rotor in the back.
