Stop on a dime.
Using trickle-down technology, the 5800 brakeset closes the gap between the 105 and Ultegra groupsets. Reporting a 10% increase in braking power, these brakes use the same symmetrical dual-pivot design found in the Ultegra and Dura-Ace groups. In order to meet the new wider tires that are so popular on road bikes these days, the brakes have taller arches that are built to clear 28mm tires.
the 105 BR-5800 brake set includes both front and rear brakes, and is available in Black or Silver.
