To keep your bike running at its best, it’s essential to clean the rear cassette, front chainrings, derailleurs, and chain thoroughly. Start by using a suitable solvent to break down tough grime. Then, use a special chain scrubber tool to reach those tricky spots and ensure that every bit of dirt is removed. After cleaning, rinse everything with water to wash away any remnants of the cleaning solution, and then dry all parts thoroughly with compressed air. Once everything is dry, apply a high-quality lubricant to the chain and moving parts to keep them smooth and rust-free. Regular maintenance not only extends the life of your bike's drivetrain but also makes each ride more enjoyable. Happy cycling!
