Thru Axles for Bikes: 12mm and 15mm Thru Axles
The Robert Axle Project makes thru axles for bikes. Replace your stock axle with a lightweight Lightning Bolt-On Axle or tow your kids with our Kid Trailer Axle. Our products allow cycling families, adventurers, commuters and enthusiasts to enjoy traveling by bicycle without leaving their cargo behind.
With our thru axles, you can lighten up your bike or attach your favorite bike trailer. We have thru axles for Burley Trailers, Thule Trailers, BOB Trailers and more—to any bicycle that has a 12mm thru axle. Find a thru-axle for any mountain, fat, road, cross, and electric bikes.
