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.
