maybe a silly question (or few)... Derailleur wiring

Hi guys,

Am about to move my deraileur to my new frame, just had a question, and apologies if this is a stupid question...

1)
Does the direction of the wire matter? My old frame, comes up from the bottom of the frame, where as the new frame is designed for the wire to come from the top. What do I need to do to adjust for that? Will the gear triggers(?) just be reversed? or maybe its not even possible?



2) when pulling the wire out, I noticed a loose thread of wire coming undone from the end a good few inches up the wire. I cut this single thread short, but its still loose. Does this matter, will it cause any issues? do I need to change the wire all together. I hope I explained this right.

3) Greasing of the Derailleur/moving components:
I have some of this Lithum grease
http://www.amazon.co.uk/gp/product/B004 ... UTF8&psc=1
is that sufficient to lubricate the moving parts of these components, or do I need something that is more liquidy and can penetrate it?


thanks again.

1. No as long as the mech is both pull.

2. Change it.

3. No need to grease. Just chain lube on the pivot points.

Depends if you're talking about the front or rear mech.
Front may be dual pull, in which case no, but if not you'll need a new front mech.
Change the cable - it will catch, and get worse and catch more. Just replace the inners and outers whilst you're at it - 99.96547871% of shifting problems are caused by cruddy cables. (scientific fact proved by me).
I wouldn't use lithium grease on anything - it turns to soap. Use silicone based grease where grease is needed, but for mech pivots etc a light oil is better.

thanks both,

very usefull points.

Well it appears its not a dual pull, so I need to purchase a new one.

When it comes to buying a front Derailleur what do I need to consider?
i.e I need to know the tube size, its got to be a Top pull/dual pull , fixed via a Clamp,

but are there any other factors I need to know to ensure compatibility?


thanks!

The swing - top or bottom (where the mech pivots from)
Lots of bike will handle both, but some won't because bits get in the way.

thanks, good to know. will stick to Top pull to be sure. anything else I need to consider before hitting ebay?

He said swing, you said pull - they are different things.

thanks! I misinterpreted the post. but cheers for alerting me to that fact, have read up on the Swing type and think I understand now.
