Here is a Lemond Poprad with a Velo-Orange Porteur handlebar, with 4600 brifters mounted. The Porteur is the 23.8 grip version. It also comes in 22.2 for flat bar type set ups.

It is quite comfortable with room for position changes, and easy access to shifting and braking.
The handlebar has a 15mm drop in the picture. No problem flipping it to give another inch + for bar height.
