Our Lightning Bolt-On thru axles offer the highest quality, simple, lightweight alternative to that bulky handle. Available in a range of sizes that fit both front and rear wheels on all types of thru-axle equipped bikes. Learn about compatibility with Hexlox security systems.

    Works perfectly. I had some issues with my stock QR thru-axles, so the upgrade to these axles has worked out great. Lightweight, low profile, exceptionally well-made. Highly recommended.

    A precision high quality thru axle that is a direct replacement for the front stock axle on my Giant TCX-CX.

    I was having issues with rotor scraping and frame flex but that was solved with RAP thu axles. So stoked to have my bike finally rides the way it should.
    Thank You RAP.

    Maybe I’m imagining it because I’m trying to justify having spent over $40 on a bolt, and maybe the issue will come back, but at this moment this current fixed issues I didn’t think had anything to do with my wheel attachment. Basically when I got out of the saddle the front end of my bike creaked like an old wooden staircase, I figured it was because it was a flexy endurance bike and not hi-mod carbon. I bought this because I thought a poor axle/fork interface was negatively impacting my brake rotor alignment. I installed this, my assumption was correct-ish, the rotor/caliper alignment was about 50% better, but then I went for a ride and I got my fat almost-clydesdale butt out of the saddle and sprinted and I heard…nothing. My bike was quiet when I was sprinting for the first time ever. Maybe it’ll come back, probably, but right now I’m attributing it to these axles since that’s all I changed. Also, I’m a nerd so I love anything I can use a torque wrench on. (which cost a bit more than this axle, hehe.)

    Great product, the machining is exquisite and great low profile. Robert Axle helped me thru the selection process without a hitch.

  12. Aaron (verified owner)

    Fantastic service and top quality machining! Will definitely buy again.

  13. Jose (verified owner)

    Amazing product! And even better customer service.
    I placed an order on a Saturday and received the axles on Wednesday (shipped to Canada) despite the fact one of the axles was out of stock.
    I’ll definitely buy more products from them when needed.

  • Purchase Robert Axle Thru axles and Hexlox locks for both your axles and for other vulnerable components.

    Here’s how:

    1. To secure your Lightning Bolt-On Axles, you’ll need one 6mm Hexlox for each axle. These include the magnetic insert for our axles which, since they are aluminum are not magnetic.
    2. Add at least one key to install and remove your Hexlox system. You will receive a key which matches the Hexlox you order. Order multiple keys if you want a spare.
    3. For other all other components, check your bike for what you want to secure. Options include Hexlox’s that fit in 4mm, 5mm and 6mm bolts, so check your bike and purchase what you need!
