Just wondering if anyone knows what the BB drop on a Bianchi Pista is.
I searched, and didn't see any actual numbers.

Something about the graphic posted by Fuzz2050 looked wrong, and s I went to the Bianchi site and looked at the graphic myself.
Somebody at Bianchi transposed a bunch of numbers or taken the numbers from a different Bianchi frame.
For example, where it says, for 590 frame, that the Pista has a 73 degree head tube angle (a very relaxed angle), the frame actually has a 75 degree head tube angle (the steepest angle of any bike in the industry).
For the correct figures, go to an earlier Pista in the Bianchi Archives, such as the 2005 Pista:
Or the 2008 Pista:
Shame on Bianchi if they changed the geometry of the sweetest handling bike I have ever ridden.

Bottom bracket drop indicates pedal clearance.
The more the drop the less the pedal clearance.
People who ride road conversions sometimes report pedal strikes in turns, because of the lower bottom bracket in road bikes.
A friend who rides a conversion, and who normally rides with 175mm cranks, had a pedal strike and has since gone to 165mm cranks.
Road bikes generally have a less steep head tube angle, a longer wheelbase, and a lower bottom bracket; all to make the bike hold a line with a little less attention.
