If the bike has sat for 10 years, you might need to take it in and have all the bearings cleaned and relubed. (I have an older MTB that sat for about 5 years. When I started riding it again, I noticed that the handlebars wouldn't turn easily. I ignored it until that stiffness caused a crash. It turned out that the headset grease had packed up and was a very stiff gummy mess.)
