That's a relatively simple service I couldn't see them charging over 10 dollars. That's about what they charge for brake adjustments and derailleur installations
Not sure what you meant by, " wheel truied" but they always tell the customer to bring their bike in to have them take a look at. They charge basically by looking at if it's a good bike, cheap bike, what brand/model-gears, etc. And go from there. Like you wouldn't charge a Bentley the way you'd charge a Toyota Corolla for an oil change... That kind of mentality they apply... From my experience.
