Recently I got a bike fit at my lbs. Since it was a Specialized store they suggested I switch out my current saddle (Brooks B17 Imperial) to the Specialized Avatar. After about 3 months of riding, I finally got tired of my butt screaming after about 15 minutes, and never being able to find the sweet spot. I switched back to my 520 gram Brooks and my butt is in heaven. I did a century on my Brooks last week with absolutely NO complaints from the culo!
