Now I will show you how to install the shift levers. When you use SRAM Trigger Shifter Levers, then your front shifter is always with your left hand. Usually, the front shifter is in board of the brake lever. I have mine between the grip and the lever so that the cable is coming out toward the centered line in the bike. We will just snug this up. I am going to route the shift cable housing.
First of all you have to make sure it's shift cable housing that its coaxial shift cable housing, it has lots of little strands. You don't want to use this for brake because there is nothing to prevent the housing other than this plastic sheet from bursting apart. Pressures are very low in shifting in compared with braking. So put that off and it's opened out nicely. You can see there is a red liner in there which you want to use lined housing.
You have the choice between 5 millimeter, 4 millimeter shift cable housing. I always get 5 millimeter because the larger that inside diameter my feeling is that the friction is lower with a 5 millimeter housing than with 4 millimeter. From the housing from the shifter ultimately I am going to be coming down here like this. I have the choice. I could run this housing tight up against the stem, but you know wherever it is, either here or there rubs the finish off the bike and so I preferred to go with the bigger loop around the head tube.
The front cable is going to come to this cable stop and I can have it come around this side for that, there is a lot of ways to do this obviously you can select however you want to do it. So I am going to cross the, cross the cables. I am going to come in here with the rear shifter cable coming out here and then for the front shifter I am coming here with the housing across the cable and go back out this way.
You have to allow some slag, you can't just come around like this because then if you turn the handle bar when this is tied up against here. Then as you turn it, it's going to pull like housing and it's going to shift your dérailleur. I am going to cut it right here. If I want I can sort of round that out a little better. This end of the tool. I might as well cut another piece, identical piece for the left shifter. We will go ahead and do that now and then the bike will be more symmetrical if I have them exactly the same way.
Now I am going to use some ferrells. Again you got 5 millimeter housing ferrells, 4 millimeter housing ferrells. Push the cable in there. This is lined housing, you saw that red liner in there. Push that into the shifter. We are going to go around stem. Here we go. Again, we will come around the stem with it. This is the front cable and this is the rear. So again we are going to cross those I will go this way. And we need to go from here, down to here.
In this case, when the suspension moves, this arm is going to move this way. It is going to push the cable housing like this. I am just making a pretty smooth curve right to there. Clip it off. That's good, work out forward, round it off a little bit. You notice this end is actually smashed. I don't know if you can see that but the red part is not open. It's pushed over from this side over to the other side. With the cable I am going to straighten that out.
So first I need to put a ferrell on there. Then I just keep pushing until I push it through and now I am just going to go like that and then that pushes the liner out toward where it needs to be. Put ferrell on that end. And you are there. That is a SRAM dérailleurs. This is a fixed a distance here. Most dérailleurs, motor dérailleurs for instance, this swings forward and you need a big loop with this SRAM. You can pretty much line it up directly. Then I am going to check the length here. Looks like if I cut it right about here, then I should have a pretty good cable routing.
Push the cable through. Push the other ferrell on the other end. Down the moment of truce. See here it's into the dérailleur. That's pretty good. It's nice. Nice cable routing. SRAM dérailleur after come around this curve piece and there is a little eyelet there. You have to thread that cable through. I have a dérailleur, there is always a spot where the cable supposed to go, see here. There is a groove right here. Go ahead and tighten that down. I want to tight it. Too tight at this point but I can clip off this long cable thereof. For this one as well. Cut on a cable end. Not now. Take us on there.
So the last piece of housing is to route from here to there for the front dérailleur. Put a ferrell on there. So obviously no movement between these two points so I don't have to worry about anything moving or changing and just want to have a smooth curve, Okay. Take a cable. Now I am going to connect my cable to the front dérailleur. I have already checked to make sure that my shift lever is in the position, that lets the most cable out. Tie the cable in. I am not going to tighten it real tight, just with the bar end. Going to go ahead and clip this wire off. As this pole is higher means that this is going to stick out more. We are going to just cut it pretty short, clip that on there, okay.
