Lightweight Thru Axles for Bikes

Lighten up. Are you looking to replace that big bulky handle on the thru-axle that came with a lightweight thru axle? Is the stock axle that came on your bike just cheap junk that comes loose all the time? These are just a few of the reasons we developed our Lightning Bolt-On Axle. We were tired of this bulky system.

The Lightning Bolt-On Axles are our lightweight thru axles for bikes and provide a better alternative to your stock axle.

Available for road, cross, gravel and mountain bikes. Use our Axle Finder to find the axle that fits your bike!
