Stock advice Store your bike in a dry, cool place. If riding or storing your bike in a salty environment, be sure to wash your bike after each use.

Your chain will require regular oil and cleaning to reduce wear and tear and damage to your drivetrain.

Frequent riding will require regular maintenance to moving parts such as your hubs, bottom bracket, headset bearings. Your local store workshop can assist you with this.
