CAUTION: If your brakes are not working properly, do not ride your bicycle. If you are at all unsure of how to
adjust your brakes, Girvin strongly recommends that you take your bike to an authorized K2 Bike dealer for
service. Improperly adjusted brakes can be extremely dangerous, and can result in failure during use and
severe injuries.
