Tightening
It is crucial to apply correct tightening force on fasteners, nuts, bolts, screws on your
bicycle so as to avoid components failure or damage, which can result in your losing
control of the bicycle and falling. Using too little force may result in the fastener not
holding securely, moving and undergoing fatigue. Applying too much force may cause
the fastener to strip threads, stretch, deform or break. If you observe any problems at the
pre-ride check, consult a professional bicycle mechanic instantly for advice. You can ride
the bicycle again only after the problem has been resolved.
