After years of mountain biking with thru-axles with bulky handles that seemed to strike every trailside obstacle, we needed a better option.

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.

SKU: LIG511 Category:


  • Lightning is Better. Our front and rear Lightning Bolt-On axles offer a stronger, more durable, lower profile and lighter weight option to replace your stock thru-axles.
  • Low Profile. No more bulky handles to strike trail obstacles or create wind drag. Aerodynamic design.
  • Light Weight. Our axles are internally bored to remove unnecessary material without compromising strength.
  • Easy to install. Our matching front and rear Lightning Bolt-On Axles only require a standard 6 mm hex wrench for easy installation and removal.
  • Better Tolerances. Manufactured in the USA to the tightest tolerances using aerospace materials and CNC manufacturing. No longer will your axle loosen while riding.
  • Available Security. Learn about compatibility with Hexlox bike security systems.

This is NOT an axle for attaching trailers or trainers.



  • The diameter of this axle is 12 mm and the true length of the axle shaft is 120 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×100 hub does not equal a 100 mm long axle.

  • Weight: 28 grams
  • The axle is precision CNC machined in the USA from 7075 aluminum and hard anodized for rugged durability. Our axles are built to the tightest standards in the industry.

    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.

  2. Alan Floyd (verified owner)

    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.

    Fantastic company with great support. I bought a front and back axle for my 2020 Giant Defy. Fit perfectly. Love em! Thanks

    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.

  14. Marcus Chard (verified owner)

    Nice product, good quality, put them on mine and my sons CX bikes.

  15. Joe Fahey (verified owner)

    Perfect match for my 2020 Lynskey GR300 with standard carbon fork. Looks fantastic, and more importantly, it works flawlessly. Shipping was fast and easy.

  16. KrikkeSteen (verified owner)

    Dankzij de goede uitleg de juiste keuze van produkt gemaakt.
    Made the right choice of product thanks to the good explanation.

  17. Bill Dister (verified owner)

    High quality, exactly what I needed and shipped very quickly.

  18. Dean Kathron (verified owner)

    Fantastic fit and finish. Saved 28g on front axle alone over stock thru axles. Weight saving, aero saving and look amazing.

  19. Frank watters (verified owner)

    Very well made and much lighter than the stock ones

  20. Mark Smith (verified owner)

    Fast and above better than the standard Lynskey QR Style axles that came on my PRO-GR

  21. Allan Nicholson (verified owner)

    Purchased a set to replace my stock 2021 Bianchi Infinito CV thru axel with the integrated lever that had developed an annoying rattle after 8 months. Worked like a charm – bike is whisper quiet again on the bumper downhills. Only point to raise is that I feel the rear one could be 3-4 mm longer.

  22. Jamie (verified owner)

    Not only a superb product, but backed with superb service. (1) I was ordering from overseas, and after taking the order they wrote back to offer me a cheaper way to do it via another country (I still stuck with the US office). (2) I accidentally received a slightly different size from the one I ordered, but the super clear instructions made that obvious right away before I assembled, and so when I asked them about it, they shipped the correct one immediately without question or cost. I was just so impressed and thankful.
    Further, it fits my bike precisely. The original thru-axle that came with my bike relied on hand tightening, which is convenient to be sure, but the fact is I essentially never take the thru-axle out, but now I can use my torque wrench to dial in the axle without worrying I’m over tightening and ruining the thread in my frame (something I’ve done before). In the event I’d take the axle out on the road, I’d have my hex key with me anyway. The only issue I can think of is when I’m tossing the bike on the race stand, since it requires me to unscrew the front wheel, and that’s more of an issue than the hand tightening method, but mildly more involved at worst.

    Great axles. Wonderful support team. Ingenious drop-down menu.
    Highly recommended.

  24. David Collazo (verified owner)

    Lost over 80 grams by replacing my stock axles. Less drag with the absence of levers. Axles are smooth and machined beautifully. Top notch products and service!

    The Mavic speed release is a pain to pull out so swapping my 700c and 650b wheelsets on my Look 765 was a pain. Problem solved.

  • 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!
