All the pedals in this test use either 6 or 8mm Allen (Hex) keys or a 15mm Spanner/Pedal Wrench. You will need the appropriate tool for your pedals and a small amount of general bicycle assembly grease.
When installing pedals, remember that the left pedal is reverse threaded – turn counterclockwise into the crank arm to install. All the pedals in this test have clear markings to indicate their side. An easy way to remember this is that you always rotate pedals forward (towards the front of the bike) to install. Most pedals mark right and left pedals to help avoid installing them on the wrong side. If you are struggling to get the threads to catch, don’t force it or you can risk damaging the threads in your cranks arms.
