Like their predecessor, the new eeSilk and eeSilk Carbon are performance suspension seatposts designed to add comfort and reduce fatigue on road and gravel rides without adding unnecessary weight to the bike. With 20mm of travel, these posts make great enhancements to gravel bikes, endurance road bikes and adventure bikes by reducing the chatter transmitted from the surface to the rider and can be tuned to rider weight through a simple to change elastomer system
