After a long hiatus from mtn biking, I'm back.

I want to change my shifter and derailleur.

Already have the parts, but want to know if there is any special technique on how to change the housing. It looks cumbersome, but I am going to do it.

I have a Giant Trance.

I also bought this red thing that looks like it will connect both new and old housing so i can just pull the old out and in with the new one simultaneously.
Also on the Shimano housing, there is a Shimano writing on one end. Does that go to the shifter side, or the derailleur side, or it doesn't matter?

Any advice is greatly appreciated.

Thanks

Do you have proper cable cutters?

If you have Shimano housing with grease in it you want to insert the cable in the end with the writing, that will pull the grease through the housing when you put the cable in. The piece is threaded right hand on one side and left hand on the other so you can thread it into both old and new housing at the same time. You can put a small allen key or a pick in the hole to help turn it. Works great.

Cool little temp splice/joint. I usually just used a inner cable to butt the new and old casing together. Andy (who has tandem cables for other than tandems )

I haven't done this yet, maybe next week. So where do I pull the housing from? Start from the shifter down to derailleur? Thanks

When pulling and inserting new internal routed casing (or inner cable for that matter) a judgement is needed WRT which direction the old is removed from. The details of the casing ports and how they affect the ability of the casing to slide along and out of (as well as the new sliding into) the tubing at the various points is the challenge. Generally a pushing force is better to try so to keep the new and old butted together. Some frames do better with the push from the rear to the front, and others the other way. How the edges of the ports interact with the casing and how the casing has to conform to other internal paths should be checked out carefully. Andy (who doesn't have a master list of which year's frame from what brand wants which direction of casing movement during replacement)

I find it depends on how easily the housing exits the frame. The direction doesn't matter, I look at both ends and pull towards what I think is the straighter (easier) exit while feeding it in gingerly. Since no pics of your frame I can't provide a definite opinion.

Edited to add..... Didn't see Andy's reply when I went to make mine, agree and he puts it so eloquently too, I'm a little rougher around the edges.

As I get older my roughness is becoming greyer Andy

I've done it easily from the top. The difficult part was removing and reinstalling the rubber covers on the frame of the bike
