  1. I have an old MTB that used to be a commuter, but now I live 50km from
    where I work it's been hanging on the garage wall for a while.

    Trouble is... the Acera X thumbshifters don't.

    It's not the first time, I recall after a period of rest they failed to
    shift once before, leaving it stuck in first gear. Got a lot of
    spinning practice riding that uphill to the LBS!

    So... what is the cause, and how easy is it to fix? I suspect it's
    gummed up lube inside the shifter housing? I'm a bit wary of taking
    the shifters apart to see, memories of long ago trying that on an old 10
    speed as a kid and having springs and things go everywhere!

    I just want a reliable hack to take me places that are close enough to
    cycle to that I now use the motorcycle for. And otherwise to hang from
    its hook and wait. Without sulking and refusing to change gears.

    You KNOW the answer to this problem... Singlespeed!

    Does the lever move at all? My AceraX's (that I
    ripped off my, now SS, GT) seemed fine. With
    this stuff, most people replace them, I think because
    they aren't really designed for servicing. I'd rip one
    apart and see what you can see. Don't expect it to
    go back together again though!. I can have a look
    at mine tonight if you want. Are you in Melbourne?
    You can probably have them. They were in pretty
    good nick, I think. Cranks and all! :-)

    Seriously though, singlespeed it. If it's just a hack bike
    and you are in Oz and you are (somewhat) fit, you
    shouldn't have heaps of trouble up the hills..

    yes, moves, just doesn't engage, the derailleurs don't move that I can
    see.

    Wouldn't be worth the money to convert it would it?
    eg. SS cog, chain tensioner, anything else?

    Maybe the cable is corroded or gummed up inside the
    cable housing?

    Certainly not for me. COuld wrestle the chain onto a suitable gear and
    ride it like that, but I'd rather get it working.

    That's looking more and more likely. But it's very anoying that it's
    the 2nd time it's done it. I thought modern cables were plastic lined
    and didn't get lubed?

    The best thing about Acera parts is that they are cheap to replace :-)

    Most cables are cheap [censored] just like they always were. Teflon coated
    ones don't need lubing but all others do, AFAIK. Except the really
    expensive goretex ones 🙂

    Having said that, it's not something I've ever paid much attention
    to.

    Cables only cost about $6 each so it might be worth doing if you're
    definitely going to ride the bike anyway.

    Oh, and maybe there's a kink in the outer cable or some [censored]
    inside it so replacing the inner cable won't fix the problem
    for very long.

    Maybe I should buy it expensive cables if I'm only going to ride it now
    and then.

    Ah well, I'll squirt something vicious down the cables and see...

    I'd take the inner cables out entirely and coat them in some thinnish
    lube and refit them. IF that doesn't work, I'd replace the whole lot.

    But then again, I use my bikes a lot and I have a very low tolerance
    for malfunctioning parts 🙂
