This Dura Ace brake cable and housing kit is identical to what comes with a set of Shimano Dura Ace 10-speed STI levers, and it's an elemental reason why Shimano Dura Ace brake calipers feel so amazingly crisp. This is a complete set of Dura Ace brake cables and and housings, with the appropriate cable tips and ferrules -- in other words, this set is enough for one entire bike.
