CRANKSETS: K-FORCE AND SL-K LIGHT WAVE SPRING WASHER COMPRESSION
I have a K-force Light/ SL-K Light crankset on my bike, and the wave spring washer is not completely compressed. Is this correct?
Yes. The wave spring on Light series carbon cranks does not need to be completely flat in order to function correctly. What is most important is that the crankbolt is tightened to the proper torque specification (45-55Nm). If a torque wrench is not used to assemble the crank, there is a risk that the crankbolt may not be tightened correctly and the crank arm can come loose and fall off while riding the bicycle causing serious accident or injury. If the crankbolt is over-tightened, the wave spring washer can be damaged, the crankarm and bolt can be damaged, and the bottom bracket may not rotate smoothly. In short: Always use a calibrated torque wrench to install MegaExo cranksets.
