Height-adjustable seat posts are becoming increasingly popular. Anyone who has ever experienced problems due to a sitting position that is too high will appreciate the safety benefit of being able to quickly lower the seat post. The ergotec UP & Down RC seat post with 21 mm offset is equipped with a remote control, which allows you to easily adjust the height while cycling without interrupting the ride. Thanks to the Safety Level 6 safety classification, this seat post is suitable for both regular mountain bikes and e-mountain bikes up to 25 km/h.
