I wish it was more useful but due to the construction. I'm disappointed. The product is well made but the way it attaches to my rear sprocket leaves something to be desired. Why? Because my sprocket has a little burr right under the teeth and this knot can't securely attach to it. What happens is I put it on and it shows my chain is misaligned. If I take it off and put it back on, the chain might look like it's aligned. You just can't tell because the mounting bolt and crest on the sprocket make assembly unpredictable. If your sprocket doesn't have this lip under the teeth, this should work just fine.
