There isn't one "traditional" bend. Cinelli tended toward drops that were a "U" on its side when looked from the side. TTT had a line that was much more of a "V". I love those "V" bars (and the many Japanese copies) with as much reach and depth as I can get. 38-40 wide for my geared bikes, 42 or more for my fix gear climbers. The more radius on the "shoulders" (where the tops round into the drops) the better, esp on the fix gears. (I hate bruised forearms from climbing out of the saddle in the drops. And I have been able to ride aero with my palms over the hoods and just my wrists on the top of the drops, no issue at all.)

My Mooney currently sports some no-name "V" track or near track bars, deep, wide, big radius shoulders. Love 'em.
