Size-Guide (Dropbox-link)



  1. Measuring usable height/stack height 
    The distance from the bottom of the seatpost collar tot he middle of the saddle rails clamp.
  2. Measuring maximum insertion length
    The distance from the top of the seatpost collar to the point, where yout seatpost stops entering deeper into your frame. The best way to measure is with the help of an old, rigid seatpost, which you carefully push into the frame. As an alternative you can also use our size-guide template, which, however, only gives sufficiently accurate orientation values for straight seat tubes: SIZE-GUIDE-TEMPLATE.
  3. Enter measured values into the Size-Guide calculator.




The size guide already includes the seatpost foot for the calculations, so it refers to the total length of the post from the center of the saddle rails to the end of the foot. The worst-case scenario is therefore considered with regard to the installation length.

"Reserve down"
This value indicates by how many millimeters (based on the selected seat position/stack heigth) the seatpost can be pushed deeper into the frame. If the displayed value is negative, the insertion depth is not sufficient for the respective seatpost.

"Reserve up"
This value indicates by how many millimeters the seatpost can be pulled further out of the seat tube ((based on the selected seat position/stack heigth). If the value is negative, the seatpost is too short.

green values: The dimensions are fine and should generally leave sufficient installation space to be able to mount the seatpost properly.

yellow values: The values should be sufficient under most conditions to be able to install the seatpost properly. It should be noted here that the cable also requires some space so that it is not kinked. Therefore, despite sufficient space for the post itself, it can lead to complications during installation. The rotatable foot of the seatpost can help here.

red values: It is rather unlikely that the respective seatpost will fit under the installation space conditions mentioned. Depending on the frame shape, the rotatable foot of the REVIVE and DIVINE can nevertheless enable successful mounting. This can be, for example, if the foot is rotated to avoid a bearing point or a slightly curved seat tube, for example, in order to be able to insert the post deeper.


  • This guide can not guarantee a proper fit, even if the dimensions suggest. 
    With short seattubes in particular, you must also check for sufficient clearence between tire and saddle (or other attachements) at full drop and fully compressed rear suspension.
  • The data refer to unshortened seatposts without reduced travel.
  • You can cut short Divine SL up to 115mm (80mm travel version).
  • The maximum extension can be reduced in 5mm increments up to 20mm.
  • In addition to the seatpost length, attention must also be paid to the appropriate cable routing in order to obtain the optimum performance.
  • If you are unsure, choose a seatpost with less travel or contact a BikeYoke dealer for advice.
  • The specifications given by the frame manufacturer for the minimum insertion depth of the frame must be observed in any case, as well as the specified minimum insertion depths of the respective seatpost!
  • BikeYoke does not guarantee the accuracy of this information, as measurement inaccuracies may occur due to peculiarities of the frame or incorrect measurement.
