Cannondale CAAD Optimo 1 Road Bike 2023
The Cannondale CAAD Optimo 1 Road Bike's SmartForm C2 aluminium frame with refined tube shapes, precision butting and clean welds guarantees low weight and a lively, enthusiastic ride character. Additionally, the frame uses its dropped seatstays and SAVE tuned flex zones to donate fatigue-reducing compliance over harsh riding surfaces. The fork, realised in Cannondale's finest BallisTec carbon, perfectly complements the frame, granting excellent lateral stiffness and reducing the severity of road vibrations reaching the hands.
A race-inspired geometry promotes agile handling and places the rider in a powerful and comfortable position over the drivetrain. The drivetrain comprises components from the well-respected Shimano 105 marque that deliver accurate gear shifts, give a wide range of gear ratios and promise exceptional power transfer. Light but robust wheels accelerate quickly, are low maintenance, and are stopped by fuss-free traditional caliper brakes. Mudguard eyelets on the frameset complete the bike and extend its versatility, enabling it to handle the harshest winter training rides.
