Sorry for my naivete but can you run w/o a chainguard? Reason I ask is that I just did the 520x ring conversion and the new d I d chain looks elegant. Hate to cover him up. On the other hand I'd hate to have it wrapped around my ankle if it ever came undone. It's the masterlink version. On the other hand if the chainguard is there more or less to keep oil off the rider I 'll deep six it as this chain runs dry. Thanks, Rick
