I was trying to replace the chainring on my Burley piccolo with something larger.
The chainring on there and the one that I bought look like this model from Niagra Cycles:
But I can't see how the chainring is attached to the crankarm. It doesn't have a little driver post engaging with the small hole in the chainring, like you'd expect on a cheap bike.
Somehow the arm is attached to the ring right at the center. I guess it's swaged together somehow, but I can't figure it out. Any thoughts?
