you can get flex levers on ebay, but they arent cheap. bark busters are a much better bet. loosen up your levers a tiny bit, so if you fall, theyll rotate around the bar instead of breaking. ive also scored the lever at the minimum point you need to operate it, then if you eat it, the whole lever isnt gone if it breaks., ive also seen guys heat thew with a torch, then curl up the end( at the same part youd score it) so the bar itself hits and not the lever.
