01 nrs ghosts shifts under load. brand new drive train ... XT, XTR chain TRUVATIVE STYLO CRANKSET.... what now??? deal with it? or is there a simple fix?

If possible, make these adjustments from the barrel adjuster on the shifter while riding. Saves a lot of time getting off the bike, adjusting the barrel on the derailler, get back on the bike, skips again, repeat process, etc., etc.deoreo said:The NRS design "tops-out" the suspension during hard pedaling (giving it that hardtail
like snap) This can also add slight tension to the rear derailleur cable causing ghost shifting.
Slightly decrease the cable tension at the barrel adjuster on the shifters, or on the derailleur.
Or, possibly due to cable routing, tension may be going slack slightly - in this case
just add a bit of tension with the adjuster.
Either way, it is definitly a cable tension adjustment problem.
I used to have a ghost shifting NRS myself, but it's smooth running now
i have heard the rear end on the earlier model NRS' are flexy, which changes the cable tension (the cable stops on the seatstay either get closer or farther away). try running full housing from the back of the top tube all the way to the derailer, and make sure the loop at the end of the seat stay to the derailer is big enough. 2004 model NRS' had full length housing just as i described for whatever that's worth.laackund said:01 nrs ghosts shifts under load. brand new drive train ...

What about the other years? Did Giant only have this problem with the early year's? I know about the difference's with the dropout locations, but what about the rest of the seatstay?angryasian said:
Giant changed the rear end design in '04. I haven't heard much about ghost shifting issues after the change so it's likely that the seatstay has been stiffened up. If you have one of these later models but still have ghost shifting issues, it would be easy enough to temporarily bypass the seatstay housing stops just to check it out.AndrewTO said:What about the other years?

Don't get me wrong - I believe what you say, that's why I posted what I did. I just wanna know about the rest of the line. I'm still learning about it.
interesting. i have an '05 NRS, otherwise the same as the '04. the outer cable/housing is already 1 piece, from the toptube all the way to the RD, so it seems Giant addressed this issue with the exact fix that's been suggested.angryasian said:Giant changed the rear end design in '04.

If this is the case, how is it that on my 2001 NRS I had to decrease cable tensionangryasian said:
Some have suggested using either zip ties or opening up the cable stops with a dremel. Myself I can't say because I don't have much time with this mod, but i'm trying the zip-tie method first simply because I don't like permanent mod's unless I know they're worth it (my weight and riding style may not necessitate this mod for all I know).laackund said:sorry it took so long to answer replys, out of town for the weekend.... anyway, after reading posts this morning i checked it out in the kitchen. i locked out the fork and brakes; when i stood on the pedals and tried to drive them forward, i could see the chain stay bowing outward a little bit. it seemed to be the most pronounced at the pivot below the cassette. the non drive side bowed some too, but it didnt appear to as much. after taking off the wheel and dismantling half of the rear triangle, i isolated that pivot to look for any play. no lateral movement, seemed to move in intended direction w/o any extra friction.... i havent tried the full length housing yet, would you suggest just using zip ties to keep it in place? also i dont have a digital camera, but ill see what i can do about borrowing one.
thanks for the help... hopefully this helps narrow things down
