Hi, having using a mountain bike for a long time, I would like to switch to a road bike.

At first, I was looking for an alu bike, but after reading a bit, it seems I will probably regret it.

So Im looking for a carbon bike with at least 105 parts. Is that a good choice for a first road bike ?

Is there any brand I should avoid ?

I was looking at Specialized bikes in particular. My mountain bike is a Specialized and I never had a problem with it in 10 years.
I like the look of the Cannondale bikes too.

I was under the impression that in this product range, you cant really go wrong.

Thank you.

P.s. Sorry for the bad phrase structure. English isnt my native language.
