自転車整備　BB（ボトムブラケット）・内装3段ギヤ・フロントハブのグリスアップ！　オーバーホール　メンテナンス

I overhauled my personal bicycle, purchased over 10 years ago. For about a year, I noticed strange noises while riding and the pedals felt heavy, so I wanted to service it, but I didn't have the time. Another reason I neglected it was because I had other bikes I could ride. I considered getting rid of it, but I figured I'd try an overhaul first to see if that didn't work. So, this is a record of the maintenance I did over the New Year's holiday. I cleaned and greased the bottom bracket (BB), internal 3-speed gears, and front tire hub. The result! It's just a bicycle! But it's still a bicycle! The pedals are surprisingly lighter! After all, bicycles are machines! I really understand the importance of regular maintenance. So, if you're having trouble riding your bike and are considering replacing it, this is a must-read. I used a variety of tools, but the only thing I did was grease it up! Please take a look.
