It’s important to wipe down your bike and bike accessories every other week during the summer and every week during the wet season. Run a moist rag along the frame, removing particles and dirt, and do the same to the chain after you’ve added some lube to it. The chain is the heart of your bike, and a dirty heart means a heart attack. It’s also a good idea to take a flat head screwdriver and hold it against the sprockets of the derailleur while turning the crank. The screwdriver will gather the muck and dirt that gets caught in your sprockets, which affect your ride.
You will notice the difference when you ride a clean bike. It puts the fun back into riding. You don’t have to pump quite as hard and when you coast down the hill, you really coast.
It’s also important to keep your tires hard. During the summer, tires tend to lose air more quickly thanks to the heat, so try giving them a squeeze to see if they could use a pump. That will also make your ride smoother and faster.
As far as self maintenance without any serious bike supplies, that’s all you need to know. To get into brake-tightening and more sophisticated bike maintenance, you need some bike accessories.
