The tape on the chain ring and the camera angle has me a bit confused as to the spacing on his bike. It looks very similar to all my cruzbikes. Just for giggles I measured the distance on all of my Cruzbikes and they were all +- 1.8 CM. Translation, I think this DR will work fine on my bikes. Based on the Cruz angle no way it drags the bottom of the cage. I suggest trying it before making a new mouse trap.
