Newbie question on "fit" for those with experience (advice sought)

[Biciclista]

People that like carbon will tell you carbon is most comfortable; i ride steel and as a scientist, i will tell you that mass absorbs vibration, so of course I believe that steel is more comfy than carbon. Carbon is very light so if your main objective is to go fast; maybe that's what you should get. They do break, but a good one comes with a replacement guarantee.
I wasn't sure at first about what felt right. Do pay for a professional fit; they can see where things are going to be a problem and then later, if something does come up, they will usually give you a "tuneup"

so you need shallower handlebars. There are many varieties out there right now for women with short arms and small hands.

I have all Campagnolo/Campi Record. it's expensive as the dickens (I got mine used) but it's GREAT!! the Veloce gruppo is less expensive
and it's a joy to use.
