Another thing is that the deep drop of the B123 came as a result of tall head tubes of bikes of that era. So riders needed to get their hands low. The EC90 sprint bars replicate that drop.
Now, bikes have moderate to low head tubes, so no need to get low. So when you use those bars with a modern bike, you have to stack spacers and use a upward rising stem.
When shallow bars like the Scatto were launched, they were a hit because the stem stack was lower and a stem could be run negative/flat.
I rode them with a 15cm head tube
