Courier crankset with mirror black finish.
- 48t chainring
GXP’s gutter seal design cuts friction, durability and weight—improving both feel and performance.
The Powerglide Chainring starts as an 7075-T6 alloy plates that go through a precise stamp, coin, and CNC process of the rings to create a precise shifting whole. Coining shapes tooth profiles into designs CNC alone can't match, creating a stronger tooth by strain-hardening the alloy for superior durability. Stainless steel pickup pins give shifting longevity. Chainring-specific finishing technologies and laser graphics add durability and appeal.
