BikeYoke presents the new REVIVE dropper post, featuring one of the most brilliant design features in dropper post technology in many years. To understand the benefits over other posts, you have to know about the problems of many current designs first: Many of the popular current seatpost designs are based on a hydraulic lockout-system, that relies on a perfectly sealing IFP (Internal Floating Piston), separating oil from air to prevent the seatpost from getting suspension feeling. There are a lot of difficulties to overcome, when using an IFP, because an IFP has to maintain 100% sealing function. If air can go to the oil side, your post will start becoming springy.
