Lightning Bolt-on Axle – Rear 12 mm x 209 mm x 1.75 Thread
After years of mountain biking with thru-axles with bulky handles that seemed to strike every trailside obstacle (including ourselves) 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.
- Available Security. Learn about compatibility with Hexlox bike security systems.
