>>1051532Kind of like this, one end of the chain wraps around the cassette, and you wrap the other end around the rim a couple of times. In this particular image the guy is using zip ties to secure the chain to the rim, but you can just loop the chain itself around the rim a couple of times and it'll hold just fine. Just gotta be careful not to fuck up the rim, hence putting something soft and thick enough between the chain and the rim.
