Have any thoughts to share?
Yes! I have the 40cm Comps on my gravel bike. As a comparison, my road bike has 38cm bars - I’m small (5’3"/160cm). I really, really love them. The shorter reach and drop are spot on for me - I find myself spending much more time in the drops than before, both on the road and off. The flare looks odd, but is very comfortable both from the hoods and in the drops. I have GRX-600 shifters, and they sit nicely.
Like that favourite saddle, it’s one of those products that you don’t even think about when riding. The Comp version is pretty good value - I couldn’t just the extra $ for the WCS version.
