I've used a handful of axle bars in the past but this is the first one I've owned and I must say, throw away your cheaper bars and upgrade.
Pros: It's 45lbs, so no silly plate math.
Center and other hand placement marks.
Nice powdercoating. Classy looking end caps.
Cons: you're a cheap bitch and don't want to spend the extra money on it.
