I have 3 bikes. (One roadie and 2 FG) All 3 sport old school Cinelli road bars in a 42cm width matched to Cinelli stems. I use 2 Model 66's and 1 Model 64.
All 3 bikes have the same distance from brake hoods to saddle tip. When I am riding on the hoods all 3 bikes have me in the same position.
I find road bars with brake hoods gives me the most hand positions for long rides.
