Flipped Butterfly Bars set where the far bars are only slightly higher than the close bar position.

Gives you a ton of hand positions.

• Normal, you have hands in the close bars where the controls are, riding mostly upright.
• Climbing, hands on the outer bars. either close in or far out.
• Stretched out: Hands on the far bars - either just stretched out or with forearms resting on the close bars.
• Comfortably stretched: Elbows at outer, close corner of bars, hands crossed to opposite side controls. Can ride like this a long time, especially if you can adjust your rear shifter with your left hand.
• Very stretched: Elbows at outer, close corner of bars, hands near center-front. A pretty good aero position (except your arms aren't pointing forward). I have a handlebar bag that I can rest my hands on, which makes this even better.
