SRAM PowerGlide Chainrings for standard cranksets with a bolt circle diameter of 130mm. Fitting for SRAM Red Black Edition and Force 2013, also compatible with SRAM Rival and Apex. Not compatible with SRAM RED Exogram crankset.
Powerglide™ Chainring Technology - starting out with raw 7075-T6 alloy plate, SRAM stamps, coins, and CNC machines 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.
