Hi Lauren - congratulations on getting that Bianchi![]()
You may hear some other names for these but one common set would be (in order of increasing reach):
tops
hoods (or brake hoods)
drops
I think using these is fairly individual and can oftentimes depend on your set-up (low seat, high seat, long stem, short stem, etc).
I use the tops & hoods while climbing as I feel I breathe much better and get more leverage - though some folks do well on the drops.
For flat riding I will gravitate more towards the hoods and drops, but at times will use the tops, especially if I am going at a moderate pace.
Enjoy your new bike and drop bars![]()
