The American Barbell Training Bar is a solid, versatile barbell for just about any application. We've tested it against the day-to-day abuse of heavy training and it's proven to last.
The bar shaft is made from precision ground alloy steel and the strength of the shaft is tested with every shipment of raw material to ensure we have a consistent 190,000 PSI tensile strength. This attention to detail also allows for excellent whip and long-term performance of our bars. The shaft and sleeves are finished in hard chrome for added durability and corrosion resistance, and the knurl pattern is crisp with just the right amount of tack.
The bar sleeves are precision machined and each one is coated with hard chrome for protection against dropping and impact. Sleeves rotate around high strength composite bushings used in aircraft and automotive industries for smooth rotation.

This was an 8th graduation gift for my son: 45 lb oly bar He had been using my wives Pendlay 35# bar but at 14 it was time to cowboy up--can't get Pendlay bars now so I got advice from one of my crossfit buddies/box owner who said he had discovered American BB and liked them -- so I ordered the "training bar" and honestly I like it better than my Pendlay 45# Great bar, well balanced, spins very well, great grip/feel!!!!
Pseudomonas aeruginosa is a metabolically versatile bacteria that can be found in numerous niches including soil, marine habitats, and on animal and plant tissues (6). P. aeruginosa is an opportunistic pathogen. Contact with humans with healthy immune systems usually does not result in infection. Immune-compromised people such as cancer patients, burn victims, and children with cystic fibrosis (CF) are more susceptible to infection by this pathogen. In children with CF, P. aeruginosa primarily colonizes the lungs, causing tissue damage that contributes to disease severity and mortality (2). Furthermore, P. aeruginosa is naturally resistant to a number of antibiotics, making it difficult to treat. Regulation of gene expression is an essential process for the survival of P. aeruginosa and for production of virulence factors that allow successful infection of its host (3). The central dogma of biology states that DNA is transcribed into messenger RNA, which is then translated into proteins. Transcription is a highly regulated process in P. aeruginosa (5). Bioinformatic studies show that 20 percent of its genome is dedicated to regulating transcription (6). Regulation of transcription can occur through modulating the activity of RNA polymerase (RNAP) by a class of proteins called transcription factors (TFs) (5). A better understanding of gene regulation by novel TFs in P. aeruginosa could lead to the discovery of new targets for antibiotic design. The objective of this study is to take a focused approach to identify potential TFs that interact with RNAP to modulate its activity. To achieve this objective we will utilize data from the Escherichia coli protein-protein interaction database (IntAct Molecular Interaction Database-www.ebi.ac.uk/intact). In E. coli, about 100 proteins were shown to either directly or indirectly interact with RNAP. Because E. coli and P. aeruginosa are in the same class of bacteria, it is possible that these proteins could be functioning as TFs in both of these organisms. Utilizing bioinformatic analysis, homologs to these E. coli proteins will be identified in Pseudomonas aeruginosa. Initially, ten P. aeruginosa homologs will be selected for further analysis in the bacterial 2-hybrid assay based on the following criteria: 1. The P. aeruginosa proteins must be greater than 70 percent identical to its E. coli counterpart, and 2. They must have no previously described interactions with RNAP. A list of these proteins can be found Table 1 in Appendix D. A bacterial two-hybrid assay will be utilized to elucidate if there is a direct interaction between putative TFs in P. aeruginosa and RNAP. In this assay, a sufficiently strong interaction between RNAP and another protein will activate transcription of a reporter gene present within a specific strain of E. coli (1). In summary, this study sets out to identify novel protein interactions with the essential enzyme RNAP. We hypothesize that if there is a sufficiently strong interaction between a particular protein of interest and RNAP, expression of the reporter gene will be activated and should cause the E. coli cells to produce blue colonies (instead of white) on agar plates. This protein could be a TF that modulates the activity of RNAP. TFs could be controlling expression of particular genes that are essential to life or virulence of the bacterium. Novel transcription factors that bind to RNAP could be potential targets for rational drug design.
Haven't tried out the bar yet but it looks amazing. Good Spin, good feel. Shipping took a little longer than usual but that's what I get for buying it during black Friday. The packaging was almost too good where I struggled to get it open. I would much rather have that than my bar be all dinged up before I could use it. So HAPPY :)
Bar appears to be excellent in quality. At the very least, it's the best I've ever owned. Now for a set of bumpers. It's too bad you're out of stock on your black bumper sets.
Great bar for the price! Smooth and quiet! Recommend it highly!
