I was wondering if anyone had a certain component that helped their bicycle split. For example:

a 26 lb bike vs a 16 lb bike
an aero tt bike (ie. Felt B2) vs a normal bike
aero wheels (ie, Zipp 404's) vs a standard wheel
ceramic berings vs standard

Does anyone know a way of telling how much these components help? 

www.Analyticcycling.com is a good resource for that type of specific information.
