diameter n. Width of a wheel
measured through its center, in millimeters (mm). E.g., 72mm.
n. The measure of a wheel's hardness, on a scale from zero to a
hundred, with one hundred being hardest. Durometer is denoted by the
suffix "A." E.g., 80A.

This can be prevented by wearing full protective gear! "I can't wait
till this road rash heals so I can wear pants again."
v. When wheels on an inline skate are configured to simulate the curve
of an ice skate blade to enhance maneuverability by shortening turning
radius. As opposed to anti-rockering, all the wheels are the same size,
but placed differently in the frame.
rotate v. To switch the
positions of inline skate wheels to prevent uneven wear.
Snell n. Foundation which tests
and certifies helmets to a high standard.
spacer n. Plastic or aluminum hub
