Which brake and Derailler cables?

Looking to purchase a set of jagwire cables(inner only) The outer sheath is less than a year old but I have a brake and derailleur cable breaking and would like to replace.

I have a 2014 Sora setup with some non Sora brakes on my 2014 Spec. Secteur.


How do I know which inner cables to use?

Use derailleur cables for the derailleurs and brake cables for the brakes.

Inner wires are pretty much universal.

Your derailleur will accept any generic inner wire but for best performance you want a stainless steel die-drawn (smooth surface) wire. Most better ones will meet that requirement.

Brake come with 2 common ends, a stepped "egg" shape for drop bar levers, and a barrel shape for most upright levers. Match the end then like with the gear wire look for one that's die drawn. Stainless steel is also nice, but not as necessary for brake as gear since most of the wire is inside the housing anyway, and marginal differences in friction aren't as critical.

I thought the wire came in different diameters as well. Does this matter and if it does, how do I know which to get?

Also, Jagwire have several varieties. Any better than any other?

Any cable better than Jagwire?

Cables die drawn after winding are smoother, so less drag .

I like to solder the place the cable will be cut , the Zn treated steel is easier to solder.

Swiss Felco is the best cable cutter.

Any cable will do. Housing matters more IMO. But even there - if not sure, get Shimano cables and housings. They are OK (and cheaper than Jagwire for all I know).

I have tried multiple brands and configurations and Jagwire products stand out as a good value. I have just replaced the longest run (rear derailleur cable) with a Jagwire "Elite ultra slick" wire derailleur cable (too expensive). I significant improvement over the teflon coated version. The jagwire "slick stainless" inner wires are a good value. If you decide to solder the ends, the Harris SBSKPOP Solder Kit will work with a the Jagwire stainless cables.

I've always found the opposite here in the UK. Shimano is a lot more expensive than Jagwire, by at least half the price, sometimes more.

In that case, I'd buy Jagwire - also very good cables and housing.

For derailleur cables, avoid the ones that are "dual-ended", e.g. a Shimano-compatible "head" on one end, and a Campy "head" on the other. To install them, you have to cut one or the other end off, and now, unless you solder the cut end, you will have a hard time threading it through your brifters without fraying. I believe the Sora levers are pretty forgiving, as they still use the old style external shift housing routing that has a very straight path through the brifter (the newer under-tape levers are hell IMHO). But single-application cables with factory soldered ends are still better IMHO.

I have some good cutters (Jagwire). The cut is nice and clean. Did cables on several bikes (all sorts of MTBs, Sora, 105 and Claris brifters) - never had much trouble. Without soldering.
