Genesis Mountain - Bolted Connections and Torque

/
If a component species a torque
for its bolted connections, then this
should be strictly adhered to. Please
read the instructions provided by the manufac-
turer, which lists the correct mounting torques.
Bolted connections
Differences for carbon components:
It is vital that all bolted connections
on the bicycle have the correct
torque in order to ensure that they
are secure. Too much torque can damage the
screw, nut or component. Always use a torque
spanner to tighten screw joints. You are not
able to correctly tighten these bolted connec-
tions without this specialist tool!
