“These didn't work for my bike. But in the process of trying to make them work I found that they were cast. If I'm being honest, I may have been attempting to bend them. The bar broke into two pieces quite close to the welds of the actual handle section. I had to put alot of stress and heat on the bar for it to break so it would probably be fine. But I didn't see consistent penetration inside the welds. Again probably fine. On the upside, these bars are ridiculously light.”
