The Factor Seatpost wedge by OKR CYCLES is the ultimate solution for the slipping seatpost on your Ostro VAM, Ostro Gravel or Hanzo frameset. After many struggles with our own bikes, we have finally decided to come up with a proper solution. Our aluminium piece replaces the cheap plastic unit supplied with the otherwise excellent Factor frames.

Our product is intricately machined from high grade aluminium and is a plug an play replacement of the standard unit. We also recommend you to use high strength thread lock on the worm bolt and the correct tightening torque (6-8Nm) for maximum security. The OKR CYCLES wedge features friction increasing ribs on the face that contacts the seatpost, however we still recommend a generous application of friction paste.

Each aspect of the OKR CYCLES Factor seatpost wedge has been meticulously designed and tested in house. You can read more about the genesis of this product in our full length article here.
