    Why do the 15kg and 10kg Starting Strength barbells not have a center knurl? When using these bars to train older or weaker folks is there any special consideration I need to take? In particular, during the lowbar squat I am wondering if not having a center knurl will cause any issues with the bar sliding. I have heard that using athletic tape can help to create some friction--is this necessary? I'm interesting in hearing what you have to say about this matter and why you designed these bars to that specification because I am considering purchasing one or more of these bars. Thanks!

    The demographic for which those bars are designed do not use heavy enough weights that a center knurl is necessary. It adds expense and not value. By the time a center knurl is useful to the lifter, the 20kg bar is being used.

    Do some lifters actually need a center knurling? In my experience, bar security (in the squat) is unaffected by the presence of a center knurling and not-sand-papering-your-neck security (in the clean) is greatly compromised.

    I have a big roll of athlete / rock climbers tape in my gym bag for when I'm away from home and stuck using a crappy gym which doesn't have centre knurled bars.

    It works a treat for me, those non centred bars are whippy mind you!

    Eleiko oly bars would be very slippery without the center knurling. Fortunately, i convinced my managers here at globogym to get me a texas power bar - its the only rusty barbell in the gym and many of my friends and members pass it over to me when I walk up to the racks.

    That's why you don't want a chrome-plated bar for general strength training.

    I squat with a chrome-plated Eleiko bar often; it really makes no difference to me in terms of bar security. (Obviously anatomical factors are at play here and your experience--just like your anatomy--is different.)

    This old texas power bar feels much more secure and way less whippy than the eleiko bars. How much are you squatting?

    Guess I have to keep being the iconoclast here, but I prefer squatting with whippy bars.
