What is it? Bicycle handlebar

Explain This The truck, moving at 58 kph (36 mph), crashed against a barricade made of steel pipes linked by a 2.5-cm (1-in.) wire-wrapped cable. The barricade's short height and immense weight (about 7,000 kg or 15,000 lbs) brought the front of the truck to a sudden halt, forcing the back to lift off the ground into a headstand. The impact also shoved the pipes forward a few meters. The government is testing these barricades to protect U.S. embassies against terrorist attacks.
