Selecting Correct Hub Width (130mm or 135mm)

The KICKR bike trainer is compatible with most modern road bikes and mountain bikes. Almost all bikes with hub widths of 130mm and 135mm work.


Selecting the Correct Hub Width (130mm or 135mm):

Typical hub widths of modern quick release frames are as follows:

  • Mountain Bikes – 135mm
  • Road Bikes – 130mm
  • Track Bikes – 120mm (not compatible)


Typical hub widths of modern thru axle bikes are as follows:

  • 130mm
  • 135mm
  • 142mm
  • 148mm (not compatible with KICKR SNAP)
  • 197mm (not compatible with any Wahoo trainer)


Thru axle bikes with a hub width of 142mm and 148mm work with the KICKR. Thru axle bikes with a hub width of 142mm require a separate adapter kit to work with the KICKR SNAP. Thru axle bikes with a hub width of 148 mm do not work with the KICKR SNAP.


If you are unsure of your frame spacing or have an older bicycle, measure the hub width to ensure a proper fit. To do this, remove the rear wheel and use a pair of calipers or a ruler to measure the distance between the inner surfaces of the dropouts.



Step-By-Step Instructions:

1)      Determine your frame’s hub spacing.

2)      Completely remove the quick release skewer.

3)      The hub width adapter is located on the non-drive side of the trainer (opposite the cassette).  Remove the adapter.

4)      Insert the spacer in the correct orientation for your bicycle. The number that remains visible after installation should match the hub width of your bicycle. If in doubt, reference the image below:
