Another diecut I thought was fairly good.  This one encloses a track chain ring.  With crankarms, there are a few different spacings.  Buy the wrong chain ring and you cannot attach it to the spider.

This diecut has a measurement chart on the back to resolve that issue.  Besdies that, I like the colours and cutouts in this.

I’ve not opend this one up as the main gist was the artwork on the back, not the actual die on this one.
