Why Choose ThruSports
The Definitive 12mm Thru Axle for Towing
Connecting a trailer to a modern bicycle shouldn't be a headache. The ThruSports 12mm thru axle is purpose-built to replace your factory axle, providing a secure, extended mounting point for your trailer hitch. Whether you are attaching a Burley Bee for the school run or a heavy-duty cargo trailer for a weekend bikepacking trip, this axle ensures your payload stays safely attached without damaging your carbon or aluminium frame.
Precision Engineered for Safety
Unlike generic skewers, our bicycle trailer axle adapter is CNC-machined from 7075-T6 aerospace-grade aluminium. This provides the immense shear strength required to handle the dynamic loads of towing up to 45kg. The M12 x 1.5 thread pitch is cut to exacting tolerances, ensuring a smooth, secure fit that won't strip your bike's delicate frame threads. It is the ultimate replacement bike thru axle for riders who refuse to compromise on safety.
Universal Trailer Compatibility
Designed with versatility in mind, the extended stainless steel stud accommodates almost all popular trailer hitches. Included in the box are precision-machined spacers, allowing the axle shaft to adjust perfectly to hub widths ranging from 160 mm to 178 mm. Stop worrying about complicated fitment charts-if your bike uses an M12 x 1.5 axle, this is the reliable, fit-for-purpose solution you've been looking for.

Customer Reviews
Spot on. I spent ages trying to figure out which adapter I needed for my gravel bike to tow our Burley Bee. The M12x1.5 pitch matched my frame perfectly, and the spacers made getting the length right a breeze.
Excellent quality replacement bike thru axle. Feels much sturdier than the one that came with my cargo trailer. Next day delivery was a lifesaver before our family holiday.
The axle itself is brilliantly made and holds the child trailer securely. My only minor gripe is that you need your own 5mm hex key to fit it, which wasn't an issue for me but worth noting.
I use this as a cargo trailer thru axle for bikepacking. The stainless steel stud takes a lot of abuse on rough Scottish gravel tracks, and it hasn't bent or loosened once. Highly recommended over the expensive American imports.
Clear instructions and a perfect fit. I was worried about stripping the threads on my carbon frame, but this bicycle trailer axle adapter threaded in smoother than the factory original.
Very solid piece of kit. It took me a little while to figure out exactly how many spacers I needed to match my old 168mm axle, but once set up, it's been totally faultless for the school run.
Great value for money. I was looking at the Robert Axle Project ones but didn't want to pay the import fees. This UK alternative is just as good, if not better, and arrived the next morning.
