Lightning Bolt-on Axle – Rear 12 mm x 162-167 mm x 1.0 Thread

(9 customer reviews)

$ 48.00

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.

SKU: LIG603 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. 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. Compatible with Hexlox bike security systems.

This is NOT an axle for attaching trailers or trainers. Please see below for “also fits your bike” if that is what you are seeking.



  • The diameter of this axle is 12 mm and the true length of the axle shaft is 167 mm. This axle comes with a tapered X-12 spacer to make the axle length 162 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.
  • This axle has a 1.0 mm thread pitch.
  • Weight: 42 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.
  • No special tools required. Design allows for installation or wheel removal using your standard 6mm hex wrench.
  • Designed, built and quality tested in the USA. Proven around the world.
  • Compatible with Hexlox security systems.

    I was looking for a replacement rear axle without the usual quick release handle, decided on the Robert Plant and couldn’t be happier, top quality build and finish. Website selects the correct part for your bike after entering your bike details so no chance of ordering the wrong part.

      Thanks for the nice review and the full belly laugh. “Robert Plant” was already taken, so was “Alan Parson’s Project”. Yep, we’re basically the best of what was left. A great reminder to never take one’s self too seriously. Love it! Happy riding!

    Great quality and fit. Fast shipping. Reasonable pricing. I was so glad to see the move in Mountain Bikes from road quick releases to Thru-Axles. I really like eliminating the lever for this Bolt-On

    Been waiting some time for this solution and finding one that fits my santa cruz is great. I like that the allen key dosen’t go all the way through so one can push on it to engage the treads on the opposite side of the frame. Sweet!

  4. Derrick M. (verified owner)

    Ordered simply to match the axle that I ordered and installed on the front of the bike. Beautiful, US machined, piece of equipment.

  5. Brian Nunn (verified owner)

    Absolutely the lightest and best. My go to for racing!

    Ordering was quick and easy with the axle finder, shipping was fast and I am very happy. I had problems with the quick release lever opening and this replacement axle hasn’t slopped at all.

  7. John (verified owner)

    After reviewing a respectable number of thru axle options, I decided on the Robert Plant (don’t think any relation to THE Robert Plant from Led Zepplin) road bike axles. The ordering process was simple and convenient, and delivery brilliant. The axles are a perfect fit and satisfy my zeal to find quality parts that are also light, yet durable.

    Perfect upgrade to my 2019 Cannondale Synapse. I also love the back story of the Robert Axle Project and always like to support small companies.

    Awesome quality, very light. Allows for repeatable torque every time compared to the clamp style axles. Highly recommend.
