This page lists the torque specifications for all parts used on your Hummingbird. If you do not
understand what torque is, or are unfamiliar with how to determine bolt size, talk to your local
bike shop or contact us.
Some parts are labelled with the torque specifications; always follow the information printed on
the part. Torque is a measurement of the tightness of a threaded fastener, such as a screw or a
bolt, determined by using a torque wrench. The torque specifications in this manual are listed to
help you determine the correct tightness of parts and their threaded fasteners.
