Hi,
I bought a second hand single speed bike today and as I was cleaning it over I noticed the hub had an additional threading on the opposite side. I'm no stranger to single speeds but I was curious whether the hub was a flip flop hub and whether you guys could help me identify if that was the case?
If it is a flip-flop pop I have a spare sprocket from a previous bike that I can use for the fixed gear side if indeed it does have on.
Thank you.
