    Mountain bike cable problems

    I crashed by sliding out around a corner and ended up with some road rash.
    My rear derailleur wasn't shifting as far out as possible. I tracked the problem down and noticed that the cable was cracked were it entered the SLX Shifter.
    I'm wondering what pieces need to be replaced and the cheapest way possible? It appears the fibers of the cable are sticking out where it enters the housing.
    To replace this do I cut the line, get a new cable, feed it in, and use the same funnel piece. The funnel piece appears to be a screw knob.

    I'm guessing the 'funnel piece' is the cable tension adjuster? That typically isn't replaced when replacing cables, if it's damaged and doesn't turn then you'll probably want to get a new one (if they're available).

    The procedure to replace the cables will be slightly different than shown in the video above, since you have Shimano shifters. In particular you typically don't need to remove Shimano shifters from the bike, and you won't need to remove the bottom cover.

    Replace the cable and housing together, it's not worth saving a few bucks by trying to reuse the housing by shortening it. You may run into problems with the housing being to short if you do that.

    If you crashed hard enough to damage your shift cable I'd check over the rest of the bike to make sure nothing else is damaged. The rear derailleur and hanger would be of concern to me.

    it appears that the housing is damage which is stretching the cable to much to get in the highest gear.

    How important is it to get expensive cables? I figured a few bucks at the local co-op or a cable kite for $40? Jagwire Mountain Pro Shift Cable Kit > Components > Cables and Housing > Shifter Cable and Housing | Jenson USA

    yes, easy to do...

    remove cable

    remove housing pieces

    bring to local bike shop

    ask them to cut you new housing same size as old pieces

    ask for replacement cable

    ----------
    or do the above yourself online and with a bike specific cable/housing cutter, or a parallel-action wire fence cutter with flat faces (flush cutter) not scissor-like cutters.

    I usually just buy some of whatever bulk housing my LBS has available.
