Overview:
Here are some Double Chainring sets for those White Industries Square Taper Road Cranks. VBC stands for Variable Bolt Circle, which in short means you can run nearly any BCD inner chainring you want which is a real plus if you like to experiment or just swap ratios around a lot. Here's a little history on it from the White Ind. site:
"When Doug saw the limitations presented by all the different bolt-circle diameters required to manufacture chainrings, he figured there had to be a better way. “Hey, how about no standard?”, and the VBC chainring system was born. VBC stands for “Variable Bolt Circle” and replaces several different bolt patterns with one simple, slotted outer chainring design that accepts a wide range of our inner VBC chainrings. The outer chainring mounts directly to the crank and serves as the mounting point for the inner chainring."
