them before you ride. On a Mountain bike or Cross bike, are the bar end extensions tight enough so you can’t twist them? If not, tighten them.
!WARNING: Loose or damaged handlebar grips or extensions can cause you to lose control and fall. Unplugged handlebars or exten-
sions can cut your body, and can cause serious injury in an other- wise minor accident.
OK: now buckle on your helmet and enjoy your ride.
