Speeed’s take
The tool that turned a brand new drivetrain from badly misaligned into clean shifting. If your gears are vague on a bike that should be fine, this is the first thing to check.
“If the derailleur is not parallel with your wheel, then it won't be parallel with all of these gears. Imagine the chain, instead of being straight, it's going to be at an angle trying to go up the gears.”
