I'm new here, but I just got my first street bike after riding a hybrid. If you are interested in clipless pedals, you can put them on your current bike. It's easier to learn on the bike you are comfortable with. Otherwise, I wouldn't put them on your new bike right away--too many changes at once!

I still don't understand the components, but pick a price range you are comfortable with--and based on the quality of bike you want. I zoned out when they started talking, but snapped back when they offered to let me ride different models. If they don't offer, ASK.

Be prepared to go to multiple bike shops--it's the end of the season and there were very few women's models on the floor in our area. It's also easier to leave when you know there are more bikes down the road. I got lucky--I bought the only female frame at the third bike shop (there was one more stop to go on the way home).

Just say you want to think about it and you will be back tomorrow. That's a polite way to get out the door.
