Specialized Butcher is ace on the back, as long as you’re not a sidewall-destroyer… Not the fastest nor the grippiest but decent at both, works on anything, and when it does slide, it slides like a boss goes where you want it, when you expect it, and comes back when called. I’ve gone off them on the front but on the back it’s mint. Light, tubeless ready, not too expensive. But, I mean that about the sidewalls, they weigh 700g so you can’t expect bombproofness. Craps on the old highroller imo in everything but super dry conditions, where to be honest it kind of sucks
