Rear Derailleur Issue

Hello,

I've only ever done very basic maintenance (IE Clean/break pad changing) however after spending a fortune makinga rip off mechanic do it at my local shop, I want to start doing more myself.

Halfway through a ride yesterday, I could no longer change gear - I could only go from my top cassette down 3, (and back up)... I immediately thought it was an issue where I'd just need to retune it, but then I took a look under the hood of my gear lever and I noticed the rear gear cable was fraying a bit. (Obviously this means an instant change is needed) but, do you also think this is the reason as for why I can't change down any further, as it can't get enough tension?

I would've attempted to change it already had I had spare bar tape handy.

Cheers.

    Fried cables will stop the mech moving as the cable can not move.

    Time for new cables inner and outer and tape.

    make sure you use some decent cable cutters to cut the cable and outers or you will ruin your new new cables. Don't use normal pliers to cut them.

    What do you mean inner & outer?

    outer is the outer cable housing, some come with a separate liner that goes inside, but usually it's all in one, inner is the cable

    note that brake outer and gear outer may look the same, but they are not, make sure you use the correct one

    if you've not done it before, simplest way is buy a set containing all the bits, for instance...

    I've bought a gear cable, I was on the understanding this could be fed through my jagwire?

    yes certainly, if the current outer is ok, no issues just changing the cable

    So it's frayed inside the lever, meaning I can't change to my largest gear meaning I can't make the nip visible to pull out of the level, meaning this is a bloody nightmare as it's frayed inside the level!

    Ideally I don't want to take it apart or buy a new lever, anyone had this before and got a work around?

    Finally got the nipple lined up, but due to having few strands left on the cable, I can't push the nipple out!
