The KICKR bike trainer is compatible with most modern road and mountain bikes. Most bikes with quick release hub widths of 130 mm and 135 mm, or thru axle hub widths of 142 mm and 148 mm will work. For a complete guide to KICKR bicycle compatibility, follow the link.
Selecting the Correct Quick Release Hub Width (130mm or 135mm):
Typical hub widths of quick release frames from the last several decades are as follows:
- 130 mm -- modern road bikes, mountain bikes prior to mid-1990s
- 135 mm -- mountain bikes prior to introduction of thru axles, early 2010s cross/gravel bikes, hybrid bikes
- 126 mm -- road bikes prior to ~1990 / 7 speed (not compatible with any KICKR, CORE, or SNAP trainer)
- 120 mm -- track bikes (not compatible with any Wahoo trainer)
Quick release bikes with a hub width of 130 mm or 135 mm generally work with the KICKR or SNAP.
Selecting the Correct Thru Axle Hub Width (142mm or 148mm):
Typical hub widths of modern thru axle bikes are as follows:
- 142 mm, "standard" -- disc road, cross, gravel, XC and trail mountain bikes
- 148 mm, "boost" -- trail, all-mountain, enduro, and downhill mountain bikes (not compatible with KICKR SNAP)
- 157 mm, "super-boost" -- fat bikes (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 bike's dropouts.
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:
