Ive suffered a bit with my R/H SRAM X9 shifter sticking and not changing down, has anyone else suffered this with SRAM shifters?
I found you could leave a shimano shifter to rot, oil it every 10 years and it will still go, these SRAM's seem to need a little more TLC.
Ive sorted it by drowning it in GT 85 and letting it soak over night.

I've got exactly the same problem, and now its becoming really hard to change up. As the GT85 still cured it for you?

The GT85 cured it for a short time but its back up to its old tricks again. Its the larger thumb lever for changing up thats stiff. It canges up OK but doesnt spring back all the way for the next shift. I like the SRAM gear, I find it a lot more sharper than Shimano, only thing is, its flippin expensive to replace!  |

Martin, I have just given mine a quick overhaul. Took the top of the shifter off and whacked a bit of grease in there, replaced the cable while I was there and they are as good as new.

I have replaced the cables. I have had the top off and de-gunged it and given it a good old GT-85ing. It kind of sorts it for a while but then it comes back.
Another problem thats started with my right shifter is it wont shift down sometimes, however if I push up hard on the thumb lever it releases.
I like the shifting with SRAM But in all my years of running shimano shifters I never had a problem even though I never serviced them!

Did you replace the inner or the outer or both? I stuck the new derailleur on at the weekend and shifting is beautiful, but I think a lot of it is because I needed a longer (new) outer at the back and the old one was full of crap stopping the cable sliding smoothly! |

New XTR inner and outer mate. The shifting is sweet, just that shifter thats being a stubborn git.

Try a bit of grease in it. I don't think GT85 lasts long as a lube, maybe as its so thin.

Yeah will give it a go. Going to give the bike a once over before Sat anyway. Will do it then.

Yeah grease the pivot, you can get spray grease which should get in there.
The thing with GT85, this is a penetrating oil as with WD40 (water displacement) - not an ideal lubricating oil in my opinion. You can use GT85 to get rid of water from coponents to prevent corrosion, but likewise will also will break down any grease within bearing sets etc if it gets in there.
I found this with my head set, and dont use it that much except to polish the frame. my chain and any moving parts get good lubricating oils only.

Im going to look at getting myself one of those small one handed grease guns I think. The thin nozzle on them shoud get into these hard to reach places.

You can get aerosol spray grease with them thin plastic tubes straw attachments to deliver the lub. Halfords do some good cheap spray grease. Also finish line have some bike specific teflon grease from chain reaction www.chainreactioncycles.com/Categories.aspx?CategoryID=243hope this helps ya. |
