I am in the market for my first road bike. I am looking to do a triathlon this summer. I have been searching everywhere for a bike. I came across a brand new Orbea Aspin for $800. I am concerned about the components. It has campagnolo xenon components. Everyone has told me to be sure and get shimano 105 components at least. Does anyone know anything about Campagnolo Xenon , are they comparable to shimano 105?
