The rolling hills of wine country. Perfect weather, flawless roads, a road bike rider's paradise. We’re not suggesting you close your eyes while riding Diamondback's Century 5 Carbon, but if you were to, it wouldn’t be hard to convince yourself that you were in this dream location. DB's latest Century line continues their tradition of all-day endurance bikes with a complete materials and design overhaul, improving on what were already rider favorites. Hand-built carbon frames borrow from their more aggressive road bikes, with big stiff bottom bracket and head tube areas, sculpted seat stays for compliance, and clean looks. Combined with hydraulic disc brakes and thru-axles, these changes are more than a superficial makeover, they represent a complete re-imagining of a modern classic. The Century 5 Carbon is the road bike for riders who wake up early and ride all day long.
