  1. Tom Hess (verified owner)

    This adapter is perfect for mounting my ’20 Trek Domane on a KICKR ’14. This solves the Wahoo thru axle issue for the Domane, Madone, and Emonda. Wahoo has no solution for the older KICKR’s but Robert Axle Project does!

  2. Collin

    Amazing product! Looks rad and works absolutely perfectly with my 2021 Cannondale Scalpel with boost spacing! Now I’m up and running on my Kickr with my mountain bike, ready to train hard and hit the races!

    I have the wahoo brand thru axle adapter for my 142mm mountain bike, and this Robert Axle Project axle is way better quality than the Wahoo brand adapter!

  3. Darcy (verified owner)

    Works like a charm on a Kickr ’14 with a 2018 Synapse Hi-Mod.
    Totally amazed by the shipping speed. Next day to Canada!

  4. James (verified owner)

    Works great! KICKR Generation 2 (2016) with a Jeffsy Core 2, 12 speed Sram NX Eagle, 12×148 axle.

  5. David (verified owner)

    I’m so glad you guys exist. Your product is top quality and works beautifully! Anyone with a wahoo with a whacky rear spacing (like 148 boost) can benefit from this beautiful product.

  6. Molly (verified owner)

    I had no idea what adapter to get for my used Wahoo Kickr. Through the chat I spoke to a real live human, had all my questions answered, and was confident I was getting the right thing. The adapter looks very cool. My second purchase from this site and couldn’t be happier.

  7. Alberto (verified owner)

    Really great product and very very fast delivery.good quality customer service is very important.excellent job guys.

    Don’t waste your money on the adapter from Wahoo… only buy the Robert Axle version. I made the mistake on buying the Wahoo version initially, and it simply didn’t work on my new Merida Reacto. Thankfully, the Robert Axle version did the job perfectly, and I didn’t need to purchase an all new Kickr.

  9. Patrick Jones (verified owner)

    I lost my Wahoo adapter in a home move. Wahoo was sold out of the adapter online and every bike shop I went to asking about it looked at me like I had 3 heads. Finally, I stumbled upon the Robert Axle version and it worked PERFECTLY! It’s honestly even better than the one Wahoo made and I didn’t have to buy a new Kickr!

  10. Jeff

    Worked perfectly and now I can use my 2016 Kickr. Thank you!

  11. Josh

    wahoo’s adapter was missing a piece when I received it which made it useless for my Canyon Ultimate.
    Then it was out-of-stock when I asked for a replacement.

    Luckily this one exists, because like the other reviews say—it is MUCH better than the wahoo adapter.

  12. Jeremy Caspell (verified owner)

    Solid fit for attaching a 2021/22 Trek Domane AL5 to a 2016 Kickr. Super stoked to not need a new trainer to fit the new bike.
    The only tweak I would make is adding a thin rubber or neoprene washer to the drive side thread-on nut to prevent metal on paint frame contact. The lever action makes the frame contact occur without any rotation, so no problems so far, but I’m clumsy and impatient, so I’d benefit from an additional layer of protection.

  13. Emilie (verified owner)

    Working perfectly on my wahoo 2014 with my 2022 Trek Emonda. Wahoo didn’t have the solution but Robert axle project yes and I’m really glad they exist!
    Plus, the next day shipping to Canada was beyond expectation.
    Highly recommand

  14. Amelia (verified owner)

    I updated my bike with the wahoo kickr 2016 version and I couldn’t find my adapters. Wahoo discontinued making them and this Wahoo KICKR Thru Axle Adapter Kit was PERFECT. The How-To YouTube video by the Robert Axle project was just what I needed for a flawless and easy installment. Thank you for providing that 🙂

  15. Eric (verified owner)

    This Kit worked perfectly for my 2014 wahoo conversion. Tried another vendor who sent the wrong kit, so don’t waste your time shopping elsewhere.

  16. Walter (verified owner)

    I bought a new SL7 Tarmac, disc brakes and was
    Told I needed to get a newer Kick’r for it. Thankfully I found everything I needed with this thru axle adapter kit, works great, well made and saved me a bunch of money for sure. Thank you guys

  17. Ozzie (verified owner)

    It Fit “Like A Glove”

  18. Conor O’Halloran (verified owner)

    Works great. Very glad this exists because without it my trainer would be useless

  19. Peter (verified owner)

    This solution solved my problem to fit my Trek Emonda 2022 on my 2015 Wahoo Kicker. The set is even better than the original alternative of Wahoo. (that isn’t available on the market any more). Also the service and delivery was in one word: perfect. 5 stars, even better.
