Updated KICKR/CORE thru axle adapter installation

Revised KICKR/CORE 142 Adapters

In 2020, several bicycle manufacturers updated the thru axle interfaces of the frames of select bike models, making them incompatible with KICKRs version 3 [2017] through version 5 [2020] and all versions of KICKR CORE. Working closely with these bicycle manufacturers, Wahoo developed an updated set of adapters allowing compatibility with affected bicycles and the above Wahoo trainers, with the exception of KICKR v3 [2017] (the updated adapters below are not compatible with KICKR v3.


Bikes known to be affected:

  • All Cervelo Disc frames
  • Lauf True Grit
  • Lauf Seigla
  • 2021+ Giant TCR Disc Models
  • 2020+ Trek Domane & Madone
  • 2021+ Trek Emonda
  • 2021+ Trek Checkpoint Carbon
  • 2021+ Trek Top Fuel
  • 2021+ Rondo Ruut AL2

Updated thru axle adapters are available for purchase on our website.

Please retain the legacy/stock adapters for future use with 148mm thru axle and QR bikes.

Because of the wide variety of bicycle makes and models available, Wahoo cannot guarantee KICKR's compatibility with all bikes.  While Wahoo has conducted tests on KICKR compatibility with certain bikes and makes note of any "Known Incompatible Bikes" on its website, it is important to note that list is not exhaustive. The KICKR end user is ultimately responsible for ensuring that his or her bike frame is compatible with the KICKR such that damage to the bike frame does not result from using the trainer.  If potential purchasers are unsure whether their bike would be compatible, Wahoo recommends visiting a local Wahoo retailer to test a bicycle’s fit before purchasing.  See https://www.wahoofitness.com/store-locator.
