Review on Enhance Your Weightlifting With Gym Weight Bar Grips For Standard Barbell, Bicep, Pull Up Bar, And More! by Dan Hansen

This product, the small size grip, seems well made of food-quality silicone. It fit snugly around my 1-inch diameter chin up bar and did not shift under load. But I returned it because the diameter is too large. I ordered it on the strength of a customer's answer that its wall thickness was 0.125 inch and thus would add only 0.25 inch to the total diameter of my bar. That would have been an ideal grip diameter of 1.25 inches. In reality, the small grip added a total of 0.625 inch, which is too much for my hand size when performing weighted chin ups. As a replacement, I have ordered a 1.00 inch I.D. x 1.25 inch O.D. silicone hose.
