Bike fit / correct riding position

not only it have a shorter top tube but also a slacker head tube - wack a longer stem on and see how you feel.

Knowing almost nothing at all about this, I've always been told that the reach is the correct length if, when you look down, the bars are about an inch in front of the axle.

At the moment the bars cover the axle, so I was thinking I needed some more room.

If it's my hamstrings being tight, then that is more easily sorted out.
