Feel stupid - chainring Q
I changed my small chainring, and when I was putting it back together I noticed the small knob on the outside of the large chainring. I had noticed it before, but never paid much attention to it.
Real question - does this knob need to be lined-up up with anything?
Curiousity question - what's the purpose of this little knob?
