Nigel Sylvester's signature seat is the first Pivotal seat to use animal's new base which is the first to rethink the structure of a Pivotal seat. The extra strong and clean design is covered with a not too thick/not too thin amount of padding and then wrapped with a durable vinyl cover that is debossed with the animal logo and Nigel's signature. To access the hollow aluminum bolt, the included 6mm allen key goes through the embroidered eye of the logo. Weight — 9.9oz
