Today, we’re going to work on internal multi speed hubs. This is the Shimano shifter. It is the Nexus model, which is written on the body. Another way to tell that this is Shimano is that the cable chord goes straight into the adjustment knob, which goes straight into the body of the shifter.
Now, the first thing you want to do is go up to the shifter on the handlebar and put it into second gear, the middle gear. You need two tools: an open end 10 mm wrench and you may also need a pair of pliers.
