Anyone know anything about disc brakes?

+ a centre punch and a very steady hand

A small left hand wound drill bit might do the job too

Alternately file it down and forget about it

^^^Those and if still no, drill and if you fuck the thread, looks like enough room to get a nut on behind?

With loctite of course.

Yup, probably wise.

It's the loctite that's the issue right now. Tried the hairdryer treatment, soldering iron. Nothing will release it! But yes there is enough space for a nut worst case... I'll go hunting for one of those drill bits shortly and report back.

In london? Ask a pro like Mario at Soho Bikes

I spoke to them on the phone yesterday and they said nope... Wasn't Mario though. Perhaps I'll call Monday as know they are demoing today.

If I put 2 and 2 together(?) - I've just liked a photo on 'gram and I see they've been using an angle grinder, the name also matches yours? Looks like you've had it worse than me and a little bolt!

Haha yeah that was crank arm and BB removal with extreme prejudice

Is Jagwire CEX cable "compressionless"?
Iv'e found it for sale described as;
Coiled Steel, non-lubed quality, low-cost brake housing using coiled Steel wrapped around an inner non-lubed liner. The combination of low cost and long-lasting performance makes the Jagwire CEX Brake Cable Housing ideal for entry-level bike service -Housing Construction: CEX low-compression housing.

I suspect it isn't - it's on a CX with Avid BB7's.

Coiled Steel

There's your answer, not compresionless.

Compressionless will be woven or linear shrouded.

Get Yokozuna Reaction, the Jagwire work well (noticeable improvement over conventional housing), but it's not a true compressionless system.

Housing Construction: CEX low-compression housing.

There it is, low compression housing translate "normal" housing.

Thanks - you've confirmed my thought.

The Yokozuna Reaction are more than I want to spend.

Any others recommended - what about the BMX cable I read of?

BMX ones are brilliant, just search on ebay for Blank or Stolen bmx cable and you'll find loads of them. Comes in plenty of colours too to annoy the haters :D

<3 this tools.

reminds me of a ball sack.

They're the ultimate housing you can get Tbh, fit and forget

If you just need outers the Goodridge stuff is compressionless, sold by the metre and is really tough (although that does mean it's not great for tighter bends)

http://www.chainreactioncycles.com/goodridge-brake-cable-outer/rp-prod23407

I'd be worried (although I don't actually know how common it is) about that splitting under load?

What do you mean by splitting under load? Is that a thing?

The goodridge housing seems really tough, been using it for 3-4 years now without any problems...

Brake cables are usually spiral wrapped, because in theory, under load it could force its way between two of the longitudinal strands, if those were used (like in gear cables). I have no idea if it is a thing though

Edit: ah, as usual, Sheldon has the answer
http://sheldonbrown.com/cables.html
(this probably predates modern compresionless brake cables though)

Ok. Lazy googling suggests brake housing has some extra layer (in this case kevlar) that must be enough reinforcement compared to regular gear cable housing... can't see how they'd get away selling it if it did split regularly...

and

vs.

The jagwire stuff has a Kevlar braid.
The good ridge stuff isn't linear. It's braided. It shouldn't split under load as expanding at one point tightens everything at another, that's the beauty of a braid.
It may be that a linear cable with Kevlar housing over it is lighter than a steel braid.

It is a thing and it still not 100% addressed, Yokozuna is the only one I can safety says is a true compression less system as inside the spiral outer, is the linear strain, so it's slightly thicker than normal but actually work (the spiral outer hold the linear inner)

Kevlar is strong but not 100% enough to stop the housing flex.

Don't forget Nokon...

If my Jagwire/Goodridge stuff fails I might consider something else, but at the moment they've both been fine on 3 bikes for several years and I the bulk of the upgrade to performance/feel/whatever over standard housing is already covered.
