OOOOOOOHH LONG JOHNSON! This is not your average youtube video of a kitty cat- this is one of the sickest stealth pivotal posts you can get your hands on! S&M bikes know exactly what they are doing - so hook up your seat in style with one of these epic posts! At 320mm, the Long Johnson post can be adjusted high enough for comfortably riding while seated, as well as low enough to be out of the way when necessary. Stealth Pivotal mounting system accepts an Allen wrench from below, not through the seat, but can also be used with a traditional Pivotal seat.
