Cannondale Capo

the frame is a double-butted chromoly steel, so yes it's heavy, but very stiff, it's an entry levels track bike for those who are keen to try out and/or complete in a track event, but with the right compound (the drop bar that came with the Bianchi are heavy steel), it can be reasonably light.

the pista is heavy and the geometry is not really track specific. changing the handlebars isn't going to make much difference to the weight, it's never going to be a light bike.

even a heavier track bike would give a zippier performance, but the compromise is the long commute will be uncomfortable as you'll feel every piece of gravel on the road.

name a heavier track bike than a bianchi pista. go on, i dare ya.

weight are usually moot since it's down to the rider, I found my Bianchi Pista to be heavier than my old Peugeot conversion (ironically enough), but the Bianchi felt lighter in term of riding.

weight is not down to the rider, it's down to mass multiplied by the force of gravity. a heavy bike may feel twitchier and turn sharper than a lighter one with slacker geometry, but a heavier object takes more energy to accelerate from one speed to a faster speed. simple physics, you can't deny it. a heavier bike takes more effort to go faster. the rider is irrelevant.
