Castelli Damping System (CDS) - The Castelli Damping System was designed and engineered to address a common problem many riders suffer from: discomfort and occasional numbness in the hands associated with extended periods of time gripping the handlebar. Castelli carefully mapped key parts of the hand in order to create optimal protection from steady road vibrations. The result is their unique palm construction that features a combination of protective materials and cushioning foams. The Castelli Damping System provides outstanding control and comfort during training or racing.
