Are 12-degree backsweep handlebars just a marketing gimmick or do they genuinely offer a tangible advantage over more traditional flat or slightly swept bars? Ive seen a lot of high-end bikes specced with these bars, but Im not convinced theyre worth the extra cost. Whats the science behind the claimed benefits of a 12-degree backsweep? Is it really going to improve my control, comfort, and overall riding experience, or is it just a bunch of hype? Can someone whos actually done some serious testing or research chime in and give me some real-world examples of how these bars have made a difference?
