It was sold to me as a 210mm but I am pretty sure it's actually 200mm.. Will update this. It's one of the Brand-X ones from CRC. Depending on how tall you are and the size of your bike, you might want to check the seatpost insertion.. If I lower this one another 20mm+ it hits on the pivot bolt. Otherwise I'd go a 240mm dropperStunner!
What dropper are you running - I'm after a longer one for my Prime v3
