Testing out a new combo of WTB Trailblazer 2.8 up front and a Breakout 2.5 in the rear, both setup tubeless perfectly. The trailblazer is good in tacky conditions, but doesn't have the bite of something like the Breakout up front when the dirt is dry.
I can honestly say that for anything outside of sloppy winter riding, I wouldn't want anything bigger than a 2.8, but that Trailblazer is a fun exercise in the effects of volume.
