Shop Thru Axles for Bike Trailers at BIKE24
A thru axle for bike trailers makes sure that your child trailer, cargo trailer, or dog trailer is mounted securely and stays firmly in place. It replaces the standard rear axle on your bike and adds a dedicated interface for you to attach the trailer hitch. What matters most is compatibility. The thru axle must match your bike’s axle standard and also have the correct thread for your trailer coupling. At BIKE24, you’ll find thru axles for all common bike trailer systems, so you can always connect your trailer safely and reliably.

Thru Axles for Bike Trailers – What to Look For
Thru axles for bike trailers mainly differ in axle standard and thread specification. The axle standard defines the diameter and hub spacing – for example, 12x142 mm means a 12 mm axle diameter with 142 mm rear hub spacing. The thread pitch (such as M12x1.5) determines whether the axle matches your frame’s internal thread. Most modern bikes use thru axles, while older bikes may still rely on quick-release skewers. What matters most is knowing the exact dimensions and thread of your current thru axle, as well as how the trailer hitch is mounted.
These criteria will help you find the right axle:
- Axle standard and hub spacing: Listed in your bike’s specs or printed on the axle itself, for example 12x142 mm or 12x148 mm (Boost). This defines the basic axle type.
- Frame thread specification: For example M12x1.5. The axle thread must match the thread in your frame exactly.
- Overall axle length and thread length: The axle must pass cleanly through the frame, derailleur hanger, and trailer hitch.
- Clearance around the rotor and rear triangle: Check clearance to the brake rotor, caliper, and stays, especially when using larger rotors.
- Trailer hitch and brand compatibility: Choose dedicated trailer thru axles designed for systems from Thule, Croozer, BOB, FollowMe, and other manufacturers.
