While a foray into hydraulic systems may seem a stretch for Thomson, which has always made static parts, keep in mind the manufacturer is first and foremost an aerospace contractor. That means that, while it would seem that Thomson is starting behind companies like Fox and RockShox, who have been manufacturing hydraulic parts for years, Thomson is actually ahead of the learning curve--and the Thomson Dropper Post makes this point obvious. The only part that the Dropper shares with its siblings is the much-loved saddle clamp. The post uses an oil cartridge to control height and a nitrogen shock to lift the mechanism. Because oil doesn't compress, the post stays put wherever your posterior leaves it, for an infinite range of adjustment. The last 15mm of travel (at the top) is damped, so your body isn't on the receiving end of a hard smack.
