I am very frugal and I used an ACS Paws as my first freewheel. I do a lot of hills. I was worried it might fail at the most dangerous time, when you’re near a peak , and moving very slowly.
At low speeds a track bike could tip over, and with cars on the left and a ditch on the right, I would be in bad shape.
I switched to White freewheel’s, learned about them right here on this forum, I now own two of them.
