HOW TO CLEAN A ROAD BIKE
What You Need
Clean your bike regularly to help prevent build-up of dirt and grease in the wrong areas, which can chew into your drivetrain and other mechanical parts. This will accelerate corrosion and result in potentially costly damage, which is why you should always clean your bike after riding in muddy or wet conditions.
Giving your road bike a thorough cleaning only takes only a few minutes to accomplish, and helps you find any wear and tear on your bicycle components before they become a larger problem. A little bit of mud speckling here and there may not do much harm, but if your bike has been through a muddy ride, you're pulling it out for the first time this season, or it's simply been a while since you've given your bike a little TLC, you'll want to get out the brushes and give it a good, thorough cleaning.
A common mistake riders make when washing their bike is praying highly-pressurized water into sealed bearings. You should use the shower setting on your hose, and avoid high-powered settings that could cause unwanted damage. Don't forget to lubricate your chain and drivetrain after cleaning, to avoid costly damages.
