grip shifters must die! (or "how to replace grip shift cable?")

I'm fixing up an old bike. The original front-derailleur SRAM grip shifter is cracked. I happen to have a Falcon grip shifter to replace the set with. For the life of me, I don't know how the damn thing threads together.

I pulled the original shifter cable out of the old SRAM shifter. The Falcon looks very similar, so I thought I was supposed to thread it back the same way. Nope. The cable would not loop through and started fraying. I opened the shifter (am I supposed to?) and tried to figure out the cabling. No clue. Wasted a shifter cable already.

How do you install the cable for a grip shifter? Google isn't helping. I see examples for fancy models with springs and levers and what not. This is a set of cheap, plastic shifters with only a single metal clip inside. Any help would be good.

My next step is to smash the thing with a hammer and buy a set of trigger shifters.

Pictures might help, but I like that step the best. I can't stand grip shifters. Note that if you get trigger shifters you'll need new longer grips.

Well the various Sram shifters have two different cable replacement methods. I'm not familiar with Falcon gripshifters. Can you share pics?

You could always just get some Sram shifters, they come with cables pre-installed.

Yup. The lower end Sram shifters have to be taken apart to replace the cable and, even at that, it's about a 3 hand job. The good news is that replacement sets don't cost much more than just the cable and come with a new cable already installed.

The big gottcha is they come in Sram and Shimano compatable so it has to match your rear derailleur and the number of rear cogs.

With the SRAM grip shifters I've used you remove a little hatch, set it aside (dont lose it), remove set screw covering the cable then remove old cable. This is on X.0 shifters. The lower end models may be different.

FWIW, I've never heard of Sram Falcon shifters. You got pics? Lower end OE spec model?

Falcon is a Chinese brand. Nashbar sells some their parts.

CHEAP SRAM grip shifters are evil ! they are fitted
with the cable installed in the grip as the bike is assembled,
replacing the cable is more difficult than replacing the whole shifter,
as it was made to go on new bikes in lower price points,
like that : whole unit.

I have done it. You peel back the rubber a little right where it turns against the fixed plastic piece. Push the old cable in as you search around the shifter with a screw driver or something thin.

One must specify model and year when speaking on cable swap technique and difficulty level.

1999 Sram MRX 7-speed shifters were quite cheap, yet only require one to peel back the rubber while pushing old cable out. New cable is then fed back in while holding the rubber back. The swap is incredibly simple.

1996 Sram SRT-600 8-speed shifters were mid-range shifters yet require partial shifter dissasembly to swap cables. My first cable change with these took quite a while and a fair amount of hair pulling for me but my most recent swap on these took about 10 minutes per shifter.

To replace the cable, remove the adjuster nut and select the lowest gear. Then peel back the rubber grip as shown and pull out the old cable. Slide in the new cable with a twisting motion to help prevent the cable from fraying.

Please note that the OP does NOT have Sram MRX shifters. I'm of the opinion he should likely get some, however. 6 and 7 speed sets are $18, 8-speed sets are $19.

Thanks for all the responses. I refused to let the shifter beat me, so I spent a good amount of time figuring it out until I got the technique right. I have a Falcon MLG-26i twist shifter, which is meant to replace my broken SRAM MRX 200-60. The mechanism, layout and installation is identical for both. Perhaps there is a way of installing it without opening the shifter, but I haven't figured that out.

I actually made a video of it so that I would remember next time I need to install another grip shift cable. My camera is not very clear, but if anyone ever needs the video, let me know and I can email it or something. It's 17MB in size, otherwise I'd post it somewhere.

I would love someone to help me out with pulling apart the falcon gripshift. I have tried to wedge it out with a screwdriver to no avail.
Any tips?

I hate them, too. Replace it with a trigger shifter. I've taken the twists apart, lost the little parts, and never been able to put them back together. This happens to me more often than successfully replacing the cable. Grr!

Man I wish I had some 1996 X-rays, even though I'm perfectly happy with my 1996 SRT-600s. The grips are totally worn out, bare plastic showing in many spots, but they shift like a mofo!

OP: I bet we have some Falcon gripshifters in the bin at the shop, I'll dig some up and investigate them sometime, perhaps Wednesday (my next day there)

Falcon shifters

I realise this is an old post but I've just done one of these and for the benefit of anyone else looking to do the same I found a great guide here and on page 16 it shows you how to thread the cable in the grip shifter: http://www.falconcycles.co.uk/manual...%20general.pdf

The trick to re-cabling SRAM Grip Shifters with the trap door is to use 1.2 mm shift cables. The smaller cables (1.1?) fray every time. This quickly leads to taking revenge on a perfectly good shifter with explosives. I don't know if working on Falcons also requires having explosives on site. bk

New cable , un cut will have the end fused, ..
soldering then cutting in the middle of the solder, is OK too.

I can file a point on the end of the cable a little bit ,
then, with the solder holding the cable together

find a set of used trigger shifters, you will be much happier.

I upgraded both kids MTBs with them and they are the best upgrade I ever did for them.

this particular set is Shimano V-brake and is bulletproof, I have never seen them break, I have swapped out plastic versions of them.
I honestly think they never made a better pair-(3 x 7 speed)

About half of those we get in do not shift. We can save about half of those with WD-40 spray fests, however.

I run into a lot of these Falcon shifters at the charity bike shop I wrench at. They are WAY more trouble then they are worth to try to recable. If a bike has them and the cable is broken of rusted frozen, we will just find a set of Sram shifters in the parts box. They are easy to recable.
