Tire circumference
You can fi nd the tire circumference (L) of your tire size in the chart be-
low, or actually measure the tire circumference (L) of your bicycle.
• How to measure the tire circumference (L)
For the most accurate measurement, do a wheel roll
out. With the tires under proper pressure, place the
valve stem at the bottom. Mark the spot on the fl oor
and with the rider’s weight on the bike, roll exactly one
wheel revolution in a straight line (until the valve comes around again to
the bottom). Mark where the valve stem is and measure the distance.
• Tire circumference reference table
* Generally, the tire size or ETRTO is indicated on the side of the tire.
