Adjusting Seat Post Tension

To adjust  the tension of the spring the hex bolt at the bottom of the seatpost needs to be turned. We recommend using a torque wrench to do so as over adjustment or under adjustment could damage the seatpost. Furthermore it could cause harm as the spring could fire out of the tube. Please note this seat post attaches into you existing seatpost saddle mount. If you also need a saddle mount we have these available in our range.
