I'd definitely do a service, as 'anonymous.shyster' suggested - To see a run down on what needs to be replaced or/and repaired. It's really pointless in saying you should do this just in case, etc... if maybe all it needs is something so small (which we all hope). But of course checks on the bike is a must! Then again maybe all it needs is a service??
What mods are on the bike? Maybe even some photos?
