On flat or downhill sections, use a higher gear for more speed. As for maintenance, regularly clean the chainrings and the spindle interface with a soft cloth and a mild cleaner. Check the tightness of the bolts periodically to ensure safety. Also, be careful not to expose the crankset to extreme weather conditions for long periods as it may cause damage. If you notice any unusual noises or difficulty in shifting, it's a good idea to have it checked by a professional bike mechanic.
