CANNONDALE CERV BIKE

The CERV features a dynamically adjustable headset that moves both fore-and-aft and up-and-down. The genius lies in achieving the above without altering the seat-to-crank height. This system puts the rider in an optimal position based on the terrain. The headset translates forward and down for a clean, low-drag position when descending. When climbing, it moves up and back, creating a more upright position for maximum leverage on the crank. Doing all this with a traditional fork in place wasn’t going to cut it, so a single-sided swing arm was proposed. Designing a forkless front-end has its own challenges, integrating it into a multi-axis adjustable system is another degree of difficulty altogether.

Priority Designs took the original concept sketch and got to work exploring mechanical solutions to the challenges presented. In addition to working through the mechanisms in SolidWorks, mock-ups were built and key components were tested. Ultimately, a proof-of-concept bike was fabricated to validate the engineering principles and define the working envelope. Cannondale reviewed the mechanical solutions and dimensional realities revealed by the test mule. A revised concept illustration was created and the team at Priority Designs was given the green light to turn the vision into a reality.
