View Full Version : 15mm bore freewheel adapter

I scored a couple of freewheel adapters for 15mm axles for 5 bucks each. A few years ago, I drilled one out to 5/8", which took a while because the adapter was really hard. This time, they drilled out really easily. I used a stepdrill from Auto-Zone on each end, and finished with a 5/8" bit I bought from HD. They now fit perfectly on the 5/8" axle.
