Converting a single speed bike to a 3 speed?

Is it possible, a 3 piece chainring (50/39/30) and a 14t rear cog
My road bike is custom built and the frame came from a geared bike

It would be so awesome if it is possible, one climbing gear, one cruising/flat gear and one sprinting/descending gear. What more do you need :D

    Good idea, you would need something to take up the varying slack in the chain.
    A rear mech fixed in one position relative to the rear sprocket would do it :D

    Whilst you'd be fine in one gear (middle chainring), it would feel pretty rough in the other two. If you want to have different gears, look at the range of Sturmey Archer hub gears.
    Make mine an Italian, with Campagnolo on the side..

    I've already got a rear mech fitted so I guess I just need a new chain and gear cable/lever

    Why would the other two rings not work well?
    I had a look at those Sturmey Archer hub gears and they do look good. Would I need to buy a new chainring and bottom bracket? And how much do you think Halfords would charge to fit it?
