Suspension + Drop. The Coast Post combines the benefits of a dropper with the joint saving squish of suspension. This witchcraft all happens via a dual chamber hydraulic cartridge featuring 40mm of tunable air suspension, designed to help riders on all types of bikes - from packed up trekkers, to the cross country wanderers, even the weekday commuters.
