Stem, handlebars, brake levers, bottle holder, saddle tube screw, brake arm screws, rear derailleur
collar and derailleur screw, screws on the front derailleur, etc. – never exceed the recommended torque
specified directly on the individual components – this may cause irreversible damage, particularly to
carbon fibre components and parts.
Check that the chainset has all the required screws and that these are tightened properly, particularly
the bolt that attaches the crank arm to the axis. If the crank arm comes loose from the axle, you must
IMMEDIATELY stop and repair the defect, otherwise, even a short ride with a “loose” crank arm may
cause irreversible damage to the crank arms. The tightness of attachment of the pedals to the crank arm
must be checked in the same manner.
