Computer designed Hyperglide (HG) sprockets incorporate specifically positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result. A superior surface treatment of CS-7800 has been applied to the titanium sporockets which increased durability by approximately 30%.
