When your pedals are making a ticking or creaking noise it probably means something is a little loose. With the correct wrench you can check if the pedals are still fixed. You can also check if the crank bolts are still correctly tightened.
Tightening the crank bolts should happen evenly and with a power of 12-14 Nm. Best to use a torque wrench. Do not tighten one and then the other.
If the ticking noise is not solved by tightening the pedals and crank, make an appointment with our bike garage.
