I went from a 38cm on my old bike to a 42cm on a new bike. It was a little too wide so I needed something in between. This is a nice alternative. I'm using it with Di2 on a Specialized Aethos and it works really well. Fits great and is comfortable on the hoods or the drops. The flare is nice as well.
I'm a short rider (5'-3') and ride a 49'. I need every inch of reach I can get so this handle bar helped me achieved that desired sweet spot. The shallow drop is also a plus. Very stiff and the flare out makes it feel a bit more stable when sprinting out of the saddle.
Great bend, great backsweep, great flair but these bars felt quite stiff when compared to the D-Fuse SLR Road bars that came on my Giant Revolt Force. Leaving my hands tired and sore after riding my local 25-mile gravel loop. I really wanted these bars and if they had a carbon version with some built-in flex, these would be gold.
