Hollowtech II design uses a wider bearing placement to maximize stiffness while keeping weight to a minimum -- what you get is a dramatically stronger pedaling force
Precision two-piece construction not only looks good, it provides perfect chainline and chainwheel alignment
Carbon composite/steel composite middle ring adds rigidity for improved shifting, increases service life and smoothly delivers power to the cassette
Outer rings are ramped and pinned for premium shifting performance
44T ring features a thicker design for added stiffness
