Built an all road bike and was looking for a softer ride after decades of rock hard 23mm 120 psi road tires, my wrists were looking for some relief. These wider bars were expensive but for me they made a difference in my wrists as did the 35mm tires. A noticeable difference over the alloy bars that I started with.
Replaced a non-flared Easton carbon bar. This bar is so much more supple it's amazing. The flare is perfect for me. I'll never go back to non-tapered drop bars on my gravel bike. Great leverage for hauling hard on climbs and great control on fast, bumpy descents.
