Step 1. Identify Your Axle Type
Quick Release Axle
The most common type of axle. The quick release axle has a lever that clamps the axle in place with an acorn nut on the opposite end.
The bolt-on axle has a hex nut on both sides. It is common on fixed gear and single speed bicycles, as well as internally geared hubs.
Thru axles are thick and hollow. They are common on newer bicycles with disc brakes, especially mountain bikes.
Step 2. Purchase Appropriate Adapter
If You Have:
A Quick Release Axle
These QR skewers replace the existing QR skewer on your bike to enable compatibility with the Coho XC cargo trailer. This adapter is required to use the Coho XC on bikes with QR skewers. Multiple skewer lengths are available.
Then You Need:
A Bolt-On Axle
The Burley Ballz Nutted Axle Adapter includes a set of threaded Ballz that replace the nuts on your current nutted axle, enabling compatibility with the Coho XC cargo trailer. This adapter is required to use the Coho XC on bikes with nutted axles. Multiple thread pitches available.
A Thru Axle
These Thru Axles enable connection of the Coho XC trailer to bikes with 12mm rear thru axles. Multiple thread pitches and lengths are available. A Burley Ballz Thru Axle is required for any bike with a 12mm rear thru axle to use the Coho XC. Use the Ballz Thru Axle Fit Guide below to determine the correct axle for your bike.
