Trouble with rear gears

[Smokin Joe]

Tool arrived today so im going to have a little play tonight!

Just a thought as ive read you should grease the gear cables, ive got some gt85 is this ok to use?
The cable i bought was clarks

You don't need to with modern cables, and adding oil or grease will attract dirt.

Ok great i didnt so thats good, i was going to remove and add some but wont bother.

Well ive just had a go with the alignment tool but screwing it in the thread is really bad on the hanger and it only went tight once right in, only a couple threads left on hanger so im going to order a new hanger now!

Do i need to find one EXACTLY the same as this as flicking online and cant seem to see one that looks identical

You should be able to find one looking for a hanger for your bike model.

Think ive found one on ebay, its a marin argenta so probably not so many about.
Looks the same and only £6.50

Just remember that will need aligning when fitted too.

Yep i was going too, I've bought the tool want to make sure it gets some use now!

 

[gazza81]

Right, hanger turned up today, used tool to straighten but STILL doing exact same thing!
I have to screw tension screw cable for it to go up through the gears which it does then it comes down and stops at the second smallest ring, i then have to unwind the tension screw for it to go into the two smallest!!

Getting pretty f'd off with it now

There has to be something fundamentally wrong somewhere. It's not that complex a mechanical system. You've now checked pretty much everything, so something must be actively faulty.

I can get it going up and down nicely untill the smallest cog now, thats the same problem the guy i bought it off had

It comes down to the third smallest then i have to click twice for it to go into second smallest but wont go into smallest

Did you fit a new section of outer where it leaves the frame and enters the derailleur, that tightly curved part is notorious for causing this problem.

 

[gazza81]

Yeah, replaced all the outers.

The only thing there is where ive been playing withi ot so much the tappered end of the outer, a little rubber tube like bit has come off but it was doing this problem before anyway

 

[gazza81]

Cable definitely the right side?

 

[Ajax Bay]

im going to fit new rear gear inner and outer cables and see how the shifting is then.

Well cassette on, new chain on, new rear gear cable and housing

Did you fit a new section of outer where it leaves the frame and enters the derailleur,

Previous posts suggest OP did.
Oil every pivot point on your RD.

I'm no expert on 105, but I think it has been mentioned before, the angle of the cable exiting towards the clamp doesn't look right I'm the first photo.

 

[gazza81]

It has, but there is a arrow and a grove for the cable to go, i tried it on the other side anyway and still the same
