Shimano rear derailleur adjustment instruction sheet says after setting the top adjustment screw (aligning to the outer line of the smallest sprocket), connect the cable by removing slack and "secure the cable by pulling it with pliers with a force of 5 - 10 kg." Anyone know what 5 – 10 kg feels like or how to measure this? Or should I just remove the slack, pull a drop more, secure cable, and then correct the tension when I adjust the index shifting? First time trying this so please be kind in responses! Thanks.
