The FIRST thing you should do is service all of the bearings and make sure the shifters/brakes work as they should. The next thing you should do it get tires that don't have knobs on them. The 3rd thing you should do is ride the heck out of it until you decide there is definitely a reason to alter it. The 930 is a great bike. I almost bought one not too long ago, but the price was too high for the amount of work it needed.
