Robert Axle Project Lightning Bolt-On Rear Thru-Axle

No ordinary thru-axle: the Lightweight Bolt-On Axle from the Robert Axle Project

If you're tired of your old, heavy thru-axle with its chunky lever, the Lightning Bolt-On thru-axle from the Robert Axle Project is a great solution. The Lightning Bolt-On has no lever to get stuck anywhere as well as an aerodynamic design. Thanks to a hollow space, this thru-axle is super light as well as super strong. It is subject to the tightest manufacturing tolerances and will therefore never come loose while riding.

The Robert Axle Project is run by the ultimate thru-axle experts. With their help you will find the right thru axle - for your trailer, your roller trainer or as a light tuning part for your MTB or road bike.

To find out which thru axle you need, you must first find out the dimensions of your current thru axle. Often the length and the thread pitch are noted on the axle itself. If not, print this template from the Robert Axle Project (in original size, do not scale) to determine the relevant data. You can also use the configuration from the Robert Axle Project, which will help you find the correct axle using parameters such as bike brand and over locknut dimension.
