The CS‑R7000 from Shimano’s 105 groupset is designed for road, cyclocross, time trial, and gravel riders who demand reliable, crisp shifting and a wide gear range without moving up to Ultegra or Dura‑Ace. The 11‑32T version gives you an extended low gear (32T) for climbing, while still keeping close steps between gears for efficient performance on flats and downhills.
Key design features include Hyperglide EV (HG‑EV) sprockets with computer‑designed tooth profiles and contoured shift gates. These offer smooth transitions even under load. The larger sprockets are supported by a lightweight alloy carrier for rigidity and reduced weight. Weight‑saving cutouts gently reduce mass without compromising strength. Finishing touches like a nickel‑plated surface and a bright steel lockring improve corrosion resistance and durability. It’s ideal for use with Shimano’s Super Narrow 11‑speed HG‑X chains.
