Which parts of my bike should I modify/upgrade?
For comfort: The first parts you should upgrade are those you physically interact with most, such as the handlebars, grips, saddle, pedals, and shifters.
For convenience: Consider upgrading components like easy wheels, a rear rack, and other accessories that enhance the practicality of your ride.
For performance and speed: Upgrade your wheelset, groupset, crankset, and other performance-oriented components to boost your riding efficiency and speed.
