seat and pedal axle

radiation man

i have got the right height of my seat now, but im still having trouble getting the seat right, i have it as far back as it will go and my knee bone is still to far in front of my pedal axle. if i move the seat forward as far as it will go im about an inch past the pedal axle, and the end of my seat is now over 1 inch before the middle of the bottom bracket any ideas or is this right.

You may possibly have the wrong size frame - is it comfortable to ride? If the saddle needs to come back more, you could try a seatpin with more setback, although this may mean too far a reach to the bars.

It does sound like too small a frame

At 5'6", I'd suggest a 56 may be too big (even though I said too small earlier). I'm six foot and ride a 56-57cm frame (although there is more to frame size calculation than height and inside leg). If you're knee is in front of the pedal axle, but you're comfortable it may not be an issue - the knee over spindle is only meant as a starting point.
