Cannondale Synapse Carbon 2 RLE Disc Road Bike 2023
Fast, comfortable and loaded with the latest technology, the Cannondale Synapse Carbon 2 RLE Disc Road Bike is a state of the art choice for long, endurance style rides and sportives. The carbon frameset delivers compliant comfort without sacrificing stiffness, ensuring a direct ride character that damps vibration whilst allowing you to put the power down on climbs and sprints. A Proportional Response carbon layup ensures whatever size you choose, you’ll receive the same high level of performance, and wide clearance allows for tyres up to 35mm in width.
A highlight of this all-new Synapse is the inclusion of the SmartSense system, which is powered by a unique, quick release battery tucked into a recess in the downtube. This model features a 350 lumen Foresite light, made in conjunction with Leyzne, and a Hindsite rear light with Garmin radar technology, which alerts the user to approaching vehicles up to 140 metres away. These lights feature an ambient light sensor and a “Brake Alert” function, which increases the rear light brightness as the bike decelerates.
This model features a high-end specification and is ideal for fast-paced sportives. The electronic Shimano Ultegra Di2 drivetrain provides pinpoint accurate shifting and easy setup and is paired with hydraulic disc brakes for confident stopping power in all conditions. Fulcrum Rapid Red 500 wheels yield rapid acceleration and lasting durability and are clad in wide 30c Vittoria Rubino Pro tyres for ultimate traction and comfort.
