Lightning Bolt-on Axle – Rear 12 mm x 159 mm x 1.5 Thread
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.
- 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.

Excellent fit and finish. Much lighter than thru axles that were on my bike.
Definitely recommending Robert Axle Project to my friends and family.

Replaced bulky stock through axles that came with my road bike with those one. Like this update: much cleaner look of a bike and weight reduction. May be not a best option for a mountain bike, as bulky throgh axles with handle give some protection to a frame. But if you don’t have intentions to crash often, buy those.
P.S. Do not forget to compare thread on stock axles and those one before installing.
