A bicycle drivetrain . The drivetrain consists of the Cranks (1), Chainring (2), Rear Sprocket (4)
, Chain (5), Rear Derailleur (3). Bicycle gears are numbered from 1 upwards, with 1 being the lowest and
easiest gear.
The lower gears are used for climbing and the higher ones are for descending. We recommend you practice shifting gears in a safe
location.
To check that your Chain is fully connected with the Chainring, rotate the Cranks and ensure no gaps or kinks are visible.
Before riding, shift through all Gears and make sure the Chain and Derailleurs are fully functional. If your Gears are not shifting smoothly, we
recommend consulting your dealer. If the Rear Derailleur is malfunctioning, do not use the highest and lowest gears of the Rear Cassette
since the Chain or Wheel may get jammed which can cause bicycle damage or rider injury.
Check all control Cables and Housings for rust, kinks, and fraying. They should be replaced if damaged.

Brakes
Make sure the Brakes are working with proper stopping power. The Levers should stop short of touching the Handlebar.
Riding with improperly adjusted or worn Brakes is dangerous and can result in injury or death. Check the Brake
manufacturer’s instructions for care and operation of your Brakes. Keep Brake surfaces clean and free from oil or lubricants.
Replace worn Brakes with authorized replacements.
