I don't think so man. You would have to find some that were homemade. Or make some yourself. I had some T bars with back sweep that were 20 wide but my buddy snapped them. I honestly don't even know what kind they were.
tsi bars or mgp 2 piece stem + mtb crossbar is the easier options. i run mgp alloy bars and mtb crossbar, very light but strong where it needs to be thanks to internal gusset at the bottom of bars
