Cannondale Quick 1 disc ladies bike - size

suegoff2007

I'm considering buying a Cannondale Quick 1 disc ladies bike secondhand on line but wary about the size. I have a medium Cannondale mountain bike at the moment but feel it is too small in reach, not height. The ladies Quick only comes in small and medium and the one I'm interested in is medium but I'm concerned about making another mistake. I'm 5'8", 32 inside leg and long arm reach. Does anyone have any idea whether the medium would be ok for me?
