frame sizes

Can someone explain how frame sizes work? I mean, in a 'Large/56' frame,
what would 56 represent?

56 cm is the length of the seat tube (from the centre of the BB to the
centre of the top tube; some are measured to the top of the seat tube.
56 cm is Ok for someone up to about 1.8m if it is a straight top tube;
a sloping one would need to be less.

Length of the seat tube, measured from the centre of the BB axle, in
centimetres. However, in these days of compact frames and sloping
top-tubes, the measurement is not nearly as useful as it used to be,
since a 56cm frame from one manufacturer may be quite different in
geometry from a 56cm frame from another (or even in a different model
from the same manufacturer).

These days, unfortunately, there's no real substitute for sitting on the
bike and seeing whether it fits.

True. I am after a frame I am familiar with and I was trying to explain
to someone what he needed to measure on the bike he was selling --just to
make sure the frame is the right size for me.

Thanks everyone for the replies.

That rather assumes you can find the model/frame size you want. The
combination I'm looking for doesn't seem to be generally held in stock at
LBS (I've tried 5 now). Happily, the shops are being helpful and offering
to order one in even though they'll be left with it if I decide not to
proceed with the purchase.
