Seat Posts

We sell the diameters that fit our bikes, but they also fit lots of bikes: 26.8mm, 27.2mm, in a range of normal lengths. They're silver, all have some degree of set-back (the clamps don't sit directly atop the shaft), and they're strong and easy to use.

They're made by NITTO in Tokyo, to NITTO's outrageous strength and finish standards.

  • *Note to other mfrs: We are happy to provide information and detailed design suggestions (beyond the geometry chart!) for no charge and no acknowledgement. If you are an established manufacture -- custom or high volume, but not just a curious hobbyist -- don't hesitate to ask, because we are happy to help. grant@rivbike.com
