replaceing rear derailer cable
NB: Originally posted elsewhere on the Global Riders Network and appears via syndication.
the rear derailer shift is getting heavy on my trance, was thinking of replaceing cable with a full lenght houseing. Any advice on brand and weather this is a good idea also was thinking of re routing it down under bottom bracket away from shock and to achieve a smoother path.

I've just ordered the Gore Ride On sealed cable system, which is effectively the same thing, with a bellows seal at the derailleur end to keep the dirt out. Seems to have had good reviews. No need to drill out cable stops.
I've been using XTR cable inner and outer to date with mixed results - great shifting but the bit of outer down near the derailleur has needed regular replacement after bad weather riding. It has been improved a fair bit by using O-ring sealed ferrules, but still eventually prone to dirt ingress.
Will report on how the Gore system goes. Pommy riders report excellent reliability in poor weather, so hoping for similar.
was just looking at Gore on CRC, were have you ordered yours from. Are you going full lenght rear
If you route the cable under the BB there is a risk of ghost shifting, particularly if the bike has a straight pull RD like SRAM units. I had this problem on a Specialised Epic once and more recently on my new felt Virtue. The problem was solved by getting the cable above the BB.
Yep, ordered from CRC. Twice the price or more if bought here. (Distributors! Grrr
)
I'm not going ot be using full length outer, they don't actually supply you with enough. However, there is a low friction sheath that sits between the outer and the cable, that covers the shifter cable in an unbroken length for the full length from shifter to the derailleur. A little bit of sheath sticks out though the end of the last ferrule and through the rear DR cable hole, and on this bit the bellows seal slides over to keep the dirt and water out of the system.
I went full length and just followed the existing cable route. I think i just used XT outer as you can by that by the meter.
A timely thread.
On the Nobmob ride at Knapsack reserve this morning, I had my RD cable snap completely.
We did a "field fix" which gave me the use of one rear sprocket in the middle of the cassette, and all three front, so I got through the ride ok.
So I'll be doing the replacement this week. Any one know a good local place to get a new XT or XTR derailler cable cheap?
I usually get mine from City Bike Depot.
Any one know a good place in Newcastle to get a new XT or XTR derailler cable cheap so i can try full length cable for rear derailer
Herzog,
It's not worth the effort shopping around. Your XT inner will cost about $12 and the outer probably similar depending on how much you need. Just go to your local bike shop. XTR is about $6 more expensive than XT inner.
Sweet. I had in my head that you had to get the whole set with hoses etc.
I have a Trance X as well and have tried a couple of full length cable routings as the original is not ideal, The next one I am going to try is to copy this http://www.robotoranges.com/2010/12/29/giant-tra... and see how it goes. It looks short and sweet and the amount of rough stuff this guy rides should mean it wont be affected by the suspension.
I bought a XTR full length outer and inner from Gateshead cycles for the trance this is version 1. so far working realy good done lap of Glenrock and !st race at awaba no problems so far.Will put up picture later when i resize them.
Sorry to drag up an old thread but I wondered how you went with the Gore cables, Hawkeye?
I'm going to do an overhaul of my bike over Christmas and wondered if the Gore is worth extra money?
As you know, haven't been riding much for the last 8 weeks, but before that... all good. I put them on both bikes in February and they've been excellent in operation. Instead of having to replace the segment of outer down by the rear derailleur after every wet ride
, I've had to do ... well, nothing at all 
Haven't had to adjust them once since, or clean them.
Yes, I would highly recommend them. Well worth the bit extra. Will pay for the difference and then some over the course of a year just on the cost of replacement parts, let alone the elimination of faffing about with cables and outers for a year or longer.
Thanks for the quick reply, I'll get some ordered.
After this last week of riding in NZ, in mainly wet conditions, they're deffinatley ready for a change.
Wiggle seems to be doing them cheapest, but god knows how long delivery will take over the Christmas period.
