Minimum insertion is 65mm and the length from the minimum insertion line to the saddle rails is 295mm. This post can be cut shorter if needed.

    ”Simple adjustment system”, it is the most difficult on the planet, Mars would be more likely to have something easier!!

    While not the easiest seatpost to adjust, its not too difficult either. If you adjust the front knurled bolt prior to tightening the rear bolt, it works pretty well. This procedure may take a couple of times to get the proper seat angle. - ed
