s3#28b/32b/38/44 "acid contrast" 1x Direct Mount 12-Speed Chainring (DM//28/32/38/44-Tooth)

Built on the same technology as the classic 144#n track bicycle chainrings, these 1x direct-mount 12-speed rings feature a unique tooth profile designed for maximum engagement and minimal wear. The double-chamfer wide teeth provide quiet and smooth tooth re-engagement at maximum chainline angle, and the beveled transition out of the narrow pocket promotes dirt clearance in the toughest conditions. Manufactured in Washington, USA, from certified 7075-T6 aluminum plate stock. These chainrings are fully CNC machined. All edges (front and rear) are machine broken with a 45-degree 0.010-in deep chamfer. Product is packaged in a custom letterpress printed envelope, and shipped USPS Priority Mail (or First Class for International orders).
