x9 rd help

[Slowbee]

During the 100 miler I picked up hassles with my RD, it would just not shift.

 

The chain stayed in the lower chain rings, and when I moved it manually it when up the rings, and then when i clicked it to go to a lower gear it worked again, but would not shift to a lower gear.

 

Why would this happen?

 

How can I fix this?

 

Is this a bike shop repair or something a newbie technician can try to solve?

Your cable's probably full of mud and guff. Remove RD and cable, flush with plenty of WD40 or similar, put back on. If you're feeling adventurous, try setting the RD up with continuous cabling. It'll work way better on days like Saturday.

[Slowbee]

ok, education on.

 

what is continuous cabling ?

 

 

 

[Slowbee]

oh yes, when i used the shifters the I could see the cable take slack and then get tight again just before the RD

Then it's definitely the last piece of cable before the RD that's gunked up. Proceed as above.

 

 

 

Continuous cabling is just that - one continuous piece of cable outer from shifter to RD. It reduces the number of entry points for the muck that slows your shifting down.

Droo, ok so help me with the ignorance here - I looked at the bike and it appears as though the cable is one continious piece already.

 

While on this why would the cable not be continious ?

The black housing that the cable runs in must be one piece and not cut so that you can see the cable itself.

Have you lubed the joints on the derraileur? The need a small drop of oil from time to time. (All eight of them)

Have you got it under control yet Slowbee? A guy I rode with last night had a jammed shifter, so check that too before you replace cables.

Making my cablehousing a continuous run has been one of the best (bang for buck) upgrades I've made to my bike. It cost less than R100 and my shifting has been perfect since. Just keep in mind that if you drill or file out your existing cable housings you'll void your frame warranty.
