  • This axle is designed to replace a rear Mavic Speed Release thru axle with a simpler, lighter weight thru axle.
  • 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. Aerodynamic design.
  • Light Weight. Our axles are internally bored to remove unnecessary material without compromising strength. 34 grams.
  • 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 165 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 12×142 hub does not equal a 142 mm long axle.

    Fits my Cannondale SystemSix rear wheel perfectly.

  2. Florian (verified owner)

    Bought the axles for my Cannondale SystemSix, they look slick and are probably more aero than the stock axles. Plus they are lighter. All in all very fine craftsmanship.

  3. Markku (verified owner)

    Bought this to my Cannondale SystemSix. Fits perfectly and looks a lot better than the bulky stock axel and saves about 30 grams of weight at the same time.

  4. Ludo Vanherf (verified owner)

    Fits perfectly on the rear wheel of my LOOK 785 DISC. Is also light.

  5. Paul Miller

    A big thank you to Tory and his excellent customer service. He went out his way to confirm I had ordered the correct rear axle, swiftly and professionally. I can confirm this Mavic Speed Release (LIG 624) fits my 2019/20 Cannondale CAAD13 rear dropouts, it’s certainly lighter than the stock lever axle and it looks sleek and less cluttered down the back end.
    Once again thanks for your excellent customer service and for a great product.

  6. David Edward Barrientos (verified owner)

    Great product and it worked flawlessly. Thank You

  7. Al (verified owner)

    I bought this axle and its front partner to replace the very non-aero speed release axles on my new aero Cannondale SystemSix. They fit and work perfectly.

  8. Dr. A. Zellner (verified owner)

    Fits my Cannondale System Six flawlessly.
    Half the weight of the oem axle.

    Perfect replacement to the bulky Mavic Speed Release axles that came with my 2020 LOOK 795 Blade RS. I like the thought of the Speed Release, but didn’t like the weight and never intend to rapidly replace wheels. I was about to re-tap my drop-outs to standard 12×1.0 thread and then luckily happened to come across this site. Thank the good lord!! I feel privileged to be running these… I am grateful Robert Axle project decided to ‘problem solve’ bikes plagued (or blessed..sorry, trying to be nice) with Mavic Speed Release. LOL. Received quickly and impressed by the precision machining. Just in love. Thank you guys!

    Amazing product. I had an issue and stripped the threads to the thru axle on my bike. The sizing sheet provided by Robert Axle project made it super easy to confirm that I got the right thru axel for my Cannondale Topstone Carbon gravel bike. Came really quick and a high quality product!

  11. Mike (verified owner)

    Very nicely made product and they sent some unsolicited help to a comment I made when ordering.

    I wish every company was as well run.

  • 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!
    4. Don’t forget to go here (link) and order our Lightning Bolt-on Axles  for your bike. Enter your bike information into our Fitment Selector database.

  • The Drive Thru is a dummy hub, or chain keeper, that replaces your wheel while cleaning the chain. It is a fast and effective way to clean your chain in between races or in your garage. It allows you to fully rotate your cranks and shift through your complete range of gears while protecting the frame. Installs simply with one hand, and is quick and easy to change between bikes. The Drive Thru is also great or packing the bike for transport. Originally developed by cyclocross legend, McGovern Cycles, now brought to you by The Robert Axle Project!

    *This Drive Thru is ONLY for Mavic Speed Release systems, as it has a unique “double lead-in” thread pitch.
