    How can I put the derailleur on left side?
    its a simple question but i fear not quite as simple as the answer is going to be, so far iv not found anything apart from how to make one from scratch to fit on the left now i would love to do this but i have left my machine shop in my other trousers and i dont think a hammer and a few spanners in the garden arnt going to do much.
    so is there a way has anyone done it or tried or am i looking at something custom built ??

    You'd need a hanger for the dérailleur on the other side, which might be do-able if it's a removable one.

    But you'd also need a freewheel that worked the other way around, and dérailleurs that worked the other way around - that might be trickier.

    Why would you want to?

    There might have been left side transmissions in the past but these died an early death.

  4. Not without a great deal of effort and a huge amount of money.You'd need a pretty good reason to embark on such a project. Do you have a good reason?

    Have you tried leaning it up against a shop window and looking at it that way?

    How much movement is required, once fitted?

    I've thought the same thing before... only because I'd like a LH bike, and a LH piano... but i have the excuse of being a very odd individual.

    I've just done it on mine actually - it was quite easy.

    Problem is it's only there when I face the bike. As soon as I get in the saddle it's on the right again. I suspect I've not tightened one of the bolts enough.

    The problem is that the angles of the shifting mechanism will probably not work as the chain is traveling in the wrong direction, and the plates will be the wrong way round.

    What may be easier would be to install some sort of "crossover drive"

    It can't be done.
    A LHD fixie, sure. There's no good reason to, but it could be done. I've done it by accident...
    But not a derailleur. You'd have to make the rear mech.

    the reason im asking is im building a new recumbent trike and iv been looking at ways for the gearing i have at the front a triple just as normal this is to go on the left and a chain runs to a second bottom bracket in the centre this has a single on the left that is the same size as the middle gear on the front triple. then on the right hand side there is a normal triple in the middle bottom bracket driving a standard rear wheel freewheel.
    basically the idea is if i have the front gears on the middle gear its a 1:1 so ride will be as normal but if i chose the smaller gear at the front i will achieve a lower gearing for hills ect and if i chose the large gear at the front then i will have higher gearing ideal for flats and down hills.
    i know there are drive systems on the market that will give me the same things with less hassle, but 1 iv not got the cash to splash about on things like that and 2 i like to make things and enjoy a challenge lol
