3T Exploro - Bolted connections

26
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 manu-
facturer, which lists the correct mounting tor-
ques.
Bolted connections
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 cor-
rectly tighten these bolted connections without
this specialist tool!
