Curious here -
What are you guys using for handlebars? What brands & what width?
I'm a light-weight enduro guy on a long track (Marymoor, 400m), in the last two years I've used FSA Energy Traditional Bend 40cm, FSA New Ergo Round 40cm, & recently switched to some no-name 38cm bars that are 31.8 all the way across the tops & super-stiff.

It's near the end of the season, and this is nothing more than curiosity.
