Bicycle Mechanics - replacing cable in Grip Shift shifter

I have Grip Shift twist-grip shifter and I need to replace the cable. When I pulled the old cable out, I noticed that it went in the side of the shifter and then curved sharply down to the where the cable housing attaches. Now I can not get the new cable in. A couple of times I was able to push the cable into the shifter, but it never came out where it should. I can't see any way to disassemble the shifter. I can look into the hole and there is a tiny place for a cable to go but I can't get it to bend that way. Does anyone have any idea how to put the cable into these shifters?

I don't have any advice, but I feel for you. I broke a set trying to get the things to go back together. They don't have the most user friendly design.

If you rotate the shifter to the forward position, 9 on the right or low on the left side, and hold the rubber flap open, you'll see a little hole in the clip that holds the cable head. Put a little grease on the bare cable end and stick it through that hole. Gently work it down the innards of the grip shifter until it comes out. These can be a real pain in the butt, but keep at it. A drop of super glue on the bare cable end before you start will keep the cable from fraying. bk

I used the same unit 11 years ago and could take the twist grip part off of the adjusting barrel portion, which allows you to thread the cable directly. Just pull them apart. There is no spring, the rear mech does that after the cable is secured.

I like the idea of super glue to keep the cable ends together.

Go here and download the document for your model shifter http://www.sram24.com/newtechdoc/english/consumers/mtb/twistshifterse.html The cheaper models are much more difficult to service than the higher priced ones.

I agree. GripShift has prodiced many different models of shifters over the years and I'm not sure if any two share a cable replacement procedure.

Some of them require disassembling the shifter to replace the cable. If you have a MRX, for example, you can buy a whole replacement shifter, with a brand new cable already attached, for only a few dollars more than the cost of just cable alone.

sram mrx comp?
black and grey component.
if you take the shifter off the bars, look toward (into) the berrel adjuster.
use a pick to snap the grey plate loose.
this should alow enough access to feed the fresh line.


yes these are a pain

They way I did it was to get a friction shifter for the FD, and get a rapid fire indexed shifter for the RD. ;)
