available and the choice of material for many professional track racing
chainrings. So you should get miles and miles and miles of use.
We used the Izumi 1/8" Super V chain as the baseline width
for this guard. So do you have to use the Super V? Absolutely Not, feel

It is no secret that chains and chainrings wear with each
other. Chain stretch is the number one reason chainrings go bad. So if
you want this all-in-one to last you as long as possible, change your
chain every year (if not twice a year) before the chain stretch ruins
the teeth. If you want to make things really easy on yourself buy a
Park CC-3C Chain Wear Indicator
and check your chain frequently.
