I believe the term "Texas Power Bar" applies to the thicker bars, right bro? Anyhow, they ALWAYS fuck me up on my bench max weights. I don't know if it is because you can't get a tighter squeeze on the bar, or if it is because TPB's tend to not bend as much, but weights to me definitely feel heavier with that particular bar, on that particular lift. Someone told me they weigh 55 lbs., but they might have been mistaken. Don't know.
the one at NY barbell is something like 18lbs...according to them. $80 with free shipping. i dont know. i want one, but i want one thats heavy duty not paper mache.
we have several thickbars at my gym and they all weigh something different....the 2" bar with knurling weighs about 75 pounds, the slick one is about 85 pounds and the 3' is heavy as hell...lol
