Cannondale CAAD Optimo 4 Road Bike 2023
The heart of the Cannondale CAAD Optimo 4 Road Bike is its SmartForm C2 aluminium frame that features sophisticated tube shapes, precision butting and clean welds to ensure low weight and rigidity for a responsive ride experience. Additionally, dropped seatstays and SAVE engineered flex zones at the rear of the frame promote excellent comfort levels over rough surfaces. Partnering with the frame, the carbon fork damps road vibrations and grants heightened lateral stiffness for powerful out-of-the-saddle accelerations.
The frame and fork are linked via Cannondale’s Elite Race geometry to guarantee agile handling and position the rider comfortably and powerfully over the drivetrain. Strong but light wheels are driven by a crisp-shifting Shimano Claris 8-speed gear setup with a wide range of ratios to ensure smooth passage over any parcours. Traditional caliper rim brakes promise low maintenance, and a stiff, lightweight alloy handlebar and stem combination make sure that steering is nimble and predictable. Mudguard eyelets on the frame and fork complete the design, transforming the bike into a trusty training steed through harsh winter months.
