Large pulley set

Usually Skinny Fat is an insult but in the case of these pulleys, it’s not. We looked at the chain and noticed that half the links are wider and half are narrower and we designed the teeth of the pulley to fit the gaps perfectly. The pulleys teeth have a fat and skinny look to them but they fit the chain like a well-tailored suit. Unlike someone who is skinny fat, these pulleys are made of strong and durable 7075 alloy.
