At only 289g for XX and a feathery 277g for XX World Cup, you can grab that slice of pie, and save the dieting for your equipment. We reengineered XX to create an impressively light brake with race-winning performance and refined TaperBore design that makes bleeding these brakes almost as fast as riding them. XX gives you the control to scrub exactly the amount of speed you need, and no more. Because when you’re at the front of the pack, every second counts. View Entire XX Series
