Ride longer, ride farther with the eeSilk and eeSilk Carbon premium suspension seatpost. The eeSilk and eeSilk carbon are comparable in weight to traditional rigid performance seatposts while offering 20mm of vertical compliance improving control on rough surfaces and reducing fatigue on long rides. These posts make great enhancements to endurance road bikes by reducing the chatter transmitted from the surface to the rider and can be tuned to rider weight through a simple elastomer change. #5 medium elastomer comes pre-installed, other weight elastomers sold separately. 25mm longer than the eeSilk Carbon to accommodate shorter seat tube lengths. Equip with updated stainless steel pivot axles, and stainless steel hardware. Weigthing in at 345g (27.2) with a 375mm post length.
