I need help on adjusting my Nexus 7 Shimano rear hub.
Today I tried to install a Shimano 7 gear shifter to change the gears on a Nexus 7 Shimano rear hub. Before installing, I lined up the red lines on the hub and I set the shifter to 4.
Next I lined up the red lines even better by the adjusting-wheel near the shifter.
The setup did work momentarily at one point. However, soon after the whole thing did not work anymore.
The problem: When I pedal hard the rear gear slips and does not drive the back wheel anymore. It is the same for every gear. I tried every position of the adjusting-wheel. After more than two hours and no success, I gave up.
Does anyone have a solution or the same problems? Is all the needed info here?
