Robert Axle Project Lightning Bolt Thru Axle - Front


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

    Their 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.


      • Lightning is Better. Their 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. Their axles are internally bored to remove unnecessary material without compromising strength.
      • Easy to install. Their 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.


      • The diameter of this axle is 15 mm and the true length of the axle shaft is 121 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 15×100 hub does not equal a 100 mm long axle.
      • This axle has a M15 x 1.0 mm thread pitch.
      • Weight: 32 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.
