The hardest thing about the SA is getting the cable tension set correctly. After a bit of trial and error, you'll get it. Bad thing is, if it's not right, the gears will shift on their own and always to the high gear. Like when you're on a hill and really need first gear but SA decides to go to third instead and all of a sudden you're trying not to fall over as you manhandle 86 gear inches up an 8% grade.
