Standard Steel or PTFE Coated Inners...

felix.london

Are the PTFE inners really worth 5x the cost of standard steel ones? £2.50 steel, £12 PTFE coated.

(will be used with a Shimano 10sp drivetrain if that makes a difference)

cooldad

No but get stainless steel ones, not plain steel.

felix.london

hmm..good point!

"Steel inner wire with anti corrosion treatment" - that's why they're so cheap!

Well spotted thanks.

£4 for stainless steel

The Rookie

I use PTFE cotaed as I have a BB routed cable that gets a lot of shite thrown at it and PTFE hold onto less than plain in my experiance, for a full length or tob tube mounted cable I'd just get stainless.

Although I paid a lot less than £12 for my PTFE inners!

cooldad

Agree, normally a few pounds on Ebay for stainless, a little bit more for PTFE.

felix.london

Merlin prices as got a couple of other bits coming from there.

Full length outer will be used although 'hopper has bare BB routing so will remember that one.

Cheers chaps

Shimano SIS? Bit out of date isn't it?

Just spray stainless steel inners with GT85 or similar ptfe spray.

Nope. not at all, that is SP41, also randomly known as XT/XTR outer. Excellent stuff. SIS just stands for Shimano Index Shifting.

cooldad

And all I use on my bikes, if that matters.

Getting pendant on you.

SIS's last S is System and SP41 could be said to be XTR.

cooldad

My most sincere apologies. Good sh1t though.

felix.london

Just didn't realise they still used the 'word' SIS. That was the height of tech, during my first mountain biking life...and that was a long time ago. Time for a new acronym Shimano

cooldad

Same system, just more gears.

felix.london

I realise that just presumed they would have come up with some marketing BS with the birth of the trigger shifter.

I still get images in my head of these little beauties which I craved for so badly when I hear SIS;

Chunkers1980

And they could be un-SISed with the little knob. Notice no knob on the front shifter - I think that was still friction.

cooldad

I actually still have a set of those on one bike.

The Rookie

Just sold a pair on fleabay for silly money.....very silly money!

Quick question - for BB routed cables do you use anything to lube the little plastic guide? Not sure if it would help or make things worse - less friction (at least to start with) versus more crap build up...

Thinking 'bout:
a) Heavy grease
b) Thin wet lube
c) Dry lube
d) Nothing

The Rookie

Nope, it's a self lubing plastic and anything wet will just attract shite!

Chunkers1980

Just a drop of chain oil or a spray of gt85 type thing is all I do. Grease just attracks crap

My 2c, regardless of outers all my issues went away when I started using a single outer from shifter to mech, this may not look so great depending on your frames routing options tho.

i was thinking about doing this as my bike is due a new set of gear cables and just run a full outer than waste money on them sealed cable sets.

i have seen an xtr cable set on ebay though for 17 which is tempting.

The Rookie

Doing a full length outer on a BB routed front cable isn't easy as you need a cable stop you don't have....
