My 2 pence worth –
i can only fit 13 inch frame !!!
Don’t get fixated on an actual number with frame size. Brands vary in size even though they may be technically the same size frame. You gotta try one, and be comfortable on it, otherwise you’re not going to get on with it. Better to spend a bit more and get a good bike that you like and will ride a lot, rather than make a “cheaper” mistake and have to start again…

EDIT – Also, when you do get a bike, let’s see some pics! Dinky FS bikes look the mutts nutts!

I totally agree with PeterPoddy’s comments. Don’t get fixated on a number, plenty of “13 inch frames” are as long as “15 inch” ones, it’s all down the the actual dimensions of each individual frame that matters.
FWIW, I would DEFINITELY look at a Giant Trance in XS size. It’s listed as being a 14 inch frame, but it has a very swoopy top tube for extra clearance when standing over it. Also, the top tubes are quite short (just over 21 inches effective I believe) which would compare well to what you are riding currently I suspect, and short of spending mega bucks on a Titus, Ventana, Orange or a Santa Cruz, I suspect that this may be about the best fit for you.

Though I have just spotted ANOTHER option… The Trek Fuel EX8 WSD. Not a cheap option at £1750, but they do an XS size too, which has a 21.2″ Top Tube, and definitely should fit you fine (I’ve known women under 5ft tall happy on XS size WSD Treks)
