Part of complete upgrade
I was replacing the original worn out equipment and went from a conventional to oval chain ring and the Cinch system makes it easy. The fit tolerance between the crank and BB require a bit of patience. I did have to use a bit of blue threadloc on the chain ring and the crank bolt though, but overall, a nice set. Customer service from Cambria on this was top notch. The first one delivered had a number of scores and scratches and was replaced without hassle.
