Gel cork by Cinelli--bumpy roads won't be a problem anymore. Also, good for those with arthritis or hand pain. The gel a more comfortable tape with the highest shock absorbing properties. The Gel VibraAbsorbr is the secret. A gel that covers the inner surface of the tape, self adhesive and perfect to wrap. Try it on the cobble stones ground or on a rough road!
Ive ridden with Cinelli cork for 20 years. Except for the extra padding, this feels the same as regular Cinelli cork to me. It is also exceptionally durable.
Ok in terms of vibration damping, but the tactile feel of the tape itself wasnt my cup of tea - like recycled plastic. Feels greasy compared to others.
