The Ultegra 6703 triple crankset features a hollowglide outer chainring similar to the top of the line Dura-Ace 7900. The hollow chainring resists flex for greater rigidity and greatly reduced chain rub. The profile of the teeth has been improved for better chain contact and a quieter drivetrain. It has improved clearance for less chain rub in the small/small gear combination versus the previous design.

The Ultegra 6703 crank employs the well-proven Hollowtech II design for both light weight and incredible bottom bracket rigidity. The Hollowtech II design makes installing and removing the crank a snap for easy cleaning and service.
