Low-Profile Alternative to Bulky Thru-Axle Levers
The Robert Axle Project 12mm Lightning Bolt Thru Axle - Rear (168mm length, 1.5mm thread) offers a high-quality, simple, lightweight alternative to conventional thru-axles with bulky handles that seem to strike every trailside obstacle. After years of mountain biking with protruding lever-style axles, the Lightning Bolt-On provides a stronger, more durable, lower profile, and lighter weight option to replace stock thru-axles. The internally bored design removes unnecessary material without compromising strength, creating an axle that's both lightweight and exceptionally strong.
Precision CNC machined in the USA from aerospace-grade 7075 aluminum and hard anodized for rugged durability, this axle is built to the tightest tolerances in the industry. The diameter is 12mm with a true axle shaft length of 168mm and a 1.5mm thread pitch. The low-profile design eliminates bulky handles that can catch on trail obstacles or create wind drag, while the aerodynamic hex socket head provides a clean, professional appearance. Installation and wheel removal require only a standard 6mm hex wrench—no special tools needed. Compatible with Hexlox security systems for added theft protection, the Lightning Bolt-On is designed, built, and quality tested in the USA and proven around the world on road bikes, gravel bikes, and mountain bikes.
