sentences:  The width is measured at the end of the drop section but the exact method varies from manufacturer to manufacturer.Some measure from outside edge to outside edge (e.g., Deda, ITM, TTT, Pinarello Most) whereas others measure from center to center (e.g., Cinelli, Profile Design, Ritchey, Salsa).The figure returned by measuring outside to outside tends to be greater than measuring center to center for the same handlebar.
