    Great solution to using a modern bike for a trailer hauler! Why trailer companies haven’t progressed is beyond me. Works flawlessly with my Thule child trailer.

    Worked great. Installation was simple, shipping was so quick! Tha Canadian money conversion with shipping made it pretty expensive but it solved my issue.

    After purchasing the 12mm thru axle for my daughters chariot it has a few issues. After greasing the axle and replacing it with my original axle I could not get it to losen up even tho I greased it and put it to the correct torque it would not let go. The 5mm hex option stripped the end and now I’m only left with my jaw locking pliers which is kind of a pain. Wish they had a different option like using a wrench.

    Wow I’m speechless in less then 10 hours they wrote back to me and are replacing my axle under warranty. I can honestly say this caught me by surprise. Amazing customer service from these guys!!!! Keep it up guys

    Awesome! Works great with my Thule Chariot (double) and my 2020 Trek Rail 7. Took the kids on long ride last weekend and they had a blast. Thanks for making such an amazing product.

    2) I got my order verified quickly.

    I was super pleased to find this. We had been looking for a solution to pulling our chariot on my bike and this nailed it. Used the axle finder to get the exact axle I needed.

    Works great on my Trek Rail! So glad to find this.

  13. Stefanie (verified owner)

    Im impressed. The search tool is so easy to use and accurate and found the exact part I needed. Even my local dealer told me there was nothing to do to attach a child trailer to my mountain bike and here the RAP has saved the day! Thank you!

    Works perfectly with my Canyon Spectral:ON. The axle was easy to install with clear instructions – even for me! The shipping was amazingly fast. Great customer experience overall, I highly recommend!
