NOTICE
• If the chainring is combined with a
standard specification right crank arm
without the chain drop prevention pin
cover, the chain may get caught between
the crank arm and the largest chainring if it
falls to the outside of the largest chainring.
• If the chainring is combined with a B
specification right crank arm with the chain
drop prevention pin cover still in place, the
cover will interfere with the crank arm, and
it will not be possible to assemble the
chainring correctly. It may cause the chain
to fall, etc.
• Removed chain drop prevention pin covers
cannot be reused.
