Hey Brian, Sorry to hear about the fit issues you're experiencing. All of our bands are designed to fit exact lug widths. (19mm, 20mm, 21mm...etc) A standard spring bar measures to 1.6mm in diameter and our Barton spring bars actually measure to 1.8mm in diameter and 0.8mm at the head in order to provide more security. It sounds like you're needing a different size and we're happy to assist with that. We encourage you to shoot us a private message as all of our products and purchases carry a 100% satisfaction guarantee within the first year of purchase and we're happy to help make things right.
