The Isaac Boson Sonic Silver road bike is a versatile racing machine designed for demanding cyclists seeking a combination of performance, comfort, and control. Its lightweight and stiff carbon frame made from Isaac Nano Carbon ACT DUAL 30 weighs 1150 grams in size L. Thanks to its comfortable geometry, it is ideal for long races and marathons where comfort is crucial without compromising performance.

The bike is equipped with hydraulic disc brakes for maximum control on descents in all weather conditions. The new integrated ISAAC Airflow 2 cockpit ensures a clean design, better cable integration, and optimized aerodynamics. Other technical features include 12 mm Thru axle, 1.5" upper and 1.5" lower headset, Press Fit BB 86.5/41 mm bottom bracket, 27.2 mm D-shaped seatpost, and tire clearance up to 32C.

This specific model offers Shimano Ultegra Di2 electronic shifting, providing precise and reliable gear changes without the need for cable system maintenance. Fast and efficient riding is ensured by the FORE FOUR 40 mm Carbon spoked wheels with a rim height of 40 mm, ideal for versatile road use.
