For 2009, the Raven Expert keeps the SSPS system: Stable Stiffness Per Size. Put plainly the larger the frame the more material is required to retain strength, stiffness and durability. This means the STW(Strength To Weight) ratio is similar for all frame sizes. This is because a tall and usually more powerful rider needs more stiffness than a shorter and normally more lightweight rider. This system avoids having wasted material and increased weight on a small frame unnecassarily, and too little material on a larger frame. Equipped with a Shimano Deore XT components, which complements this bike along with Fulcrum Red Metal 5 wheels, Avid Elixir R hydraulic brakes for superior braking, Concept Extreme stem/barends and FSA bars/seatpost you have a race ready bike or an exceptional fast trail machine.
