Features

ergotec ATAR 550 is a patent aluminum seat post with 2-bolt clamping and 15 mm offset to the rear. This is suitable for saddles with 7 and 8 mm thick struts-D. The ATAR seat post is now also available diameters of 33.9 mm and 31.6 mm. This eliminates the need for additional seat post bushings.

Easy Adjustment of Components. You can adjust the pretension via the screw-on end cap in order to regulate the progressive steel spring characteristics curve to suit your preferences. Also, you can easily adjust the damping to the rider’s weight by replacing the spring.

High Suspension Comfort and Low Breakaway Torque. Based on the combination of perfectly adjusted spring damping and reduced piston friction thanks to low-friction bushings, the telescopic post offers high suspension comfort and a low breakaway torque. Thus, the suspension seatpost quickly responds to the adjusted pressure while reliably guiding the tube for best saddle support.
