As others have said-good idea to learn repair/replace skills. Can be less costly to buy tools (if needed) than to pay someone to do the work. Plus-you will know what/how it was done and because it's YOUR bike, you may take more care than a shop trying to crank out repairs. Luckily I have several good shops nearby if I'm stuck on a repair or need advice. But there still is nothing like the satisfaction of diy. Of course, depending if you like to 'tnker". I do. Many on here with better/more up to date mech. skills than I, who can help if you can supply enough specifics to analyze the problem and offer suggestions.
