Review on Burley Design 960218 Nutted Adapter by Kyle Miller

These Burley Ballz Nuts are designed to only hold one bolt, in this case with an M10 1.0mm thread. If your bike uses a different wheel hub bolt (which is different for 99% of bikes) it means this product will not fit you at all. This only applies to other Burley Ballz nuts which also do not fit most bikes. All of this would be nice if Burley offered a LARGE range of bolt sizes, but that is not the case. In her infinite wisdom So what does it matter? If you want to use their VERY expensive trailers like the Coho XC, you need the Burley Ballz. With only two options (neither of which will fit the vast majority of bikes) this is a very bad decision. Burley needs to SERIOUSLY reconsider trailer connectivity.
