15mm Lightning Bolt-on: Length 158 mm M15 x 1.5 (LIG503)

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.

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 or create wind drag. 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.
This is NOT an axle for attaching trailers or trainers.
