The G.2 ST-XXL parallelogram suspension seatpost represents the best by,schulz quality.

This is illustrated by the 3D forged aluminum construction, which aims to provide maximum stability even for heavy riders – or the spring mechanism, which runs on high-performance polymer plain bearings, thus guaranteeing finely responsive suspension and top riding comfort.

And to ensure that enthusiastic (e-)city and touring riders enjoy maximum riding pleasure on bumpy dirt roads or rough gravel sections, the built-in steel spring is available in five spring rates – to match the rider’s weight. Due to its progressive nature, the G.2 ST-XXL with its 30 mm spring travel, optimally controlled even with heavy impacts. The G.2 ST-XXL suspension post makes saddle and suspension changes child’s play; the rider weight range extends from 45 to 150 kg.

If the tube diameter of the seat post does not match the frame seat tube, the difference can be adjusted with a G.Shim reduction sleeve.

The Mudcover neoprene cover protects against dirt and weather and is included in the scope of delivery.

  • For saddle racks with Ø 7mm, optionally available for Ø 8mm

The parallelogram suspension seat post was developed to offer you maximum riding comfort, both in the city and on rough terrain. The suspension is designed to be progressive, i.e. the system reacts softly to light impacts and with increasing spring resistance to hard impacts.

When compressing, the G.2 LT parallelogram suspension seatpost dips up to approx. 33.5mm backwards and approx. 40.5mm downwards.

Thanks to the use of a heavy-duty flat steel spring and technical elastomers in the spring eye and on the inside of the arms, even hard impacts (e.g., when driving through deep potholes) do not cause the suspension to bottom out. In addition, the rearward spring movement is dampened by the hemispherical elastomers in the head and base sections. For optimal adjustment of the G.2 LT offers easily interchangeable spring elements with 5 different spring rates and dampers to suit the rider’s weight and riding style.

  • Make sure that the inner diameter of the seat tube of the bicycle frame and the outer diameter of the G.2 ST or G.2 LT seat post have the same value.
  • Different dimensions can lead to failure of the clamp and to accidents and damage to property or personal injury.
  • The tube diameter of the seat post can be adapted to the size of the seat tube using a reducing sleeve. To adapt the seat post tube, we recommend the G.Shim double-slotted aluminum reducing sleeve from by,schulz. The following diameters and lengths are available:

  • If you use a reduction sleeve from another manufacturer, it should be made of aluminum and have a minimum length of 90 mm. Make sure that the reduction sleeve is always fully inserted into the seat tube.
  • Check that the width of the saddle frame is compatible with the head of the seat post. It must not be less than 36 mm on the inside. Some core leather saddles are too narrow at the front of the frame and therefore cannot be combined with the seat post. Such use is not possible and can cause permanent damage to the saddle and seat post.

  • Always use the right saddle clamp for the corresponding saddle frame. Saddle clamps for a saddle frame with Ø 7mm are fitted as standard. If necessary, saddle clamps with Ø 8mm can be fitted. Never combine Ø 8mm clamps with a saddle frame with Ø 7mm or vice versa. Note: Saddles with oval saddle rails must not be used.
