### Instruction: How should I maintain my bicycle?
### Response: Keep your bicycle clean. Most important of all, keep your bicycle’s drivetrain clean. A bicycle’s drivetrain is the chain, chainrings and pulleys which make the rear wheel turn. If you can, wipe down the drivetrain with a cleaning lubricant made for bicycle drivetrains after each long ride, or every other short ride. Doing so will ensure that your ride is noticeably more enjoyable. Shifting will remain smooth and reliable, and pedaling will be easier. Dirty drivetrains are squeaky and loud. Your clean drivetrain will be nice and quiet. Your clean drivetrain will also last much longer since you are regularly cleaning away the dirt and other road grit and sweat which collects in the chain and grinds away everything it touches. If you are unable to maintain your bicycle, take it to the local bike shop at least once a year for maintenance and tune up. You won’t regret it.
