If you are new to riding, or even just out of shape, some of the typically more aero and lower positions won't be comfortable. However as your body adjusts, you might find you like getting more stretched out. So keep checking that.

Big thing is as you ride more and more and your body changes and adapts to your riding, then you'll want to change things up on your fit any how. Might even want to change bikes in a year or two, so keep that in mind.

Consider what your goals are too. Match the bike to the riding you are going to do.
