Ensure that your pedals are tightened to at least 310 in-lbs (35 Nm) every 5 minutes
for the first few rides. Before fitting, it's also a good idea to make sure your pedal axles are clean (a wire brush works well) then greased before installation.
Similarly, always check the black, M6 pinch bolt torque is at least 88 in-lbs (10 Nm) every 5 minutes
for the first few rides, then each and every ride after that.
Failure to keep your pedals or crank bolts tight as described above is likely damage your cranks and this will not be covered under warranty.
The red, aluminium pre-load bolt featured on these cranks should not be used to tighten them on. This is used only to pull the cranks together and pre-load the bearings. It requires only "nipping" into place, and damage caused by over-tightening is not coverable by warranty.
