All of a sudden it seems to be raining ultra light droppers. About the same time that Tyler was writing up the story on the 295g FRM dropper post yesterday, I was reading an email from Oscar from JBG2 DPS about a very similar looking dropper post. However, Oscar claims that JBG2 DPS was first, and that their post is lighter. Because carbon.
Both the JBG2 DPS and the FRM use a design that is the opposite of a traditional dropper – the seat mast cap rides on the outside of the main tube which allows for an ultra light build. The posts have nearly identical specs with a total length of 400mm and 60mm of dropper travel. Posts are available in 27.2, 30.9, and 31.6mm diameters, too, however the JPG2 has a slightly better 95kg (209lb) rider weight limit. The biggest differences include the use of carbon fiber and a cable entry point that sticks out at 90° from the seatpost.
Those small changes add up to a 240g claimed weight, though they show one post on the scale at 220g without the cable, housing, and remote. Either way, it’s lighter than the FRM post by at least 55g – though at €1,049, you’re certainly paying for it. We’re told that they do not have a web store at the moment, but posts can be purchased by contacting JBG2 through email.
