NGS 2 service & maintenance

The Eightpins seat post has the advantage that the seat post tube can be removed and installed very quickly and the sliding bushings can be cleaned or replaced quickly. If the sliding properties deteriorate, the seat post can be quickly relubricated via a grease nipple in the outer sleeve. Small jobs such as cleaning and greasing the sliding bushings as well as changing the cable can be carried out by following the instructions. The prerequisite is an existing technical understanding and the correct tools. 
The following activities must be carried out regularly:
