The knurling on this thing is no joke, it locks into your hands even when you're sweaty mid-deadlift. I was worried the aggressive texture would chew up my palms, but it's actually exactly what I needed for heavy pulls. Chalk up, and this bar does not budge.

The knurling on this bar is genuinely aggressive—it bites into my hands on heavy pulls without needing chalk every other rep. I’ve only had it a few weeks, but the 29mm shaft feels exactly right for deadlifts and squats, and it hasn’t shown any wear yet.

The 29mm shaft feels rock-solid in my hands, even on heavy deadlifts, and the knurling bites just enough to keep the bar from slipping without shredding my palms. I've used it for three sessions now and it's already become my go-to for squats and pulls.
