TECH TIPS
• There are three types of chainrings: those with a chain guard on both the front
and rear sides, those with a chain guard only on the outside, and those with no
chain guard. The explanation in this section uses one without a chain guard.
3. Install the chain.
Refer to the dealer's manual for the chain to use.
4. Secure the chainring.
