They were developed specifically for the SRAM Apex 1 crank with an asymmetrical 110 millimeter bolt circle. The chainrings have optimized teeth that prevent the chain from coming off. The principle follows that of the Shimano chainrings. In conjunction with a Shimano Shadow+ rear derailleur, which has a greatly increased pretension on the cage, the chain is reliably held in position even without a chain guide.\u003cbr\u003e\n\u003cbr\u003e \nOvalizing the chainring increases performance by varying the drivetrain and optimizing resistance. Kicking with your legs brings your natural strengths and weaknesses into harmony. In this way, better use of the stronger muscle groups is achieved and the weaker muscles are compensated for the commute (smaller stroke).\u003cbr\u003e\n\n\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e Areas of use: gravel, cyclocross, racing bike\u003c\/li\u003e\n\n\u003cli\u003e Material: aluminum 7075 Txxx\u003c\/li\u003e\n\n\u003cli\u003e Technology: Narrow Wide\u003c\/li\u003e\n\n\u003cli\u003e Bolt circle: 110 mm (asymmetric design of the SRAM Apex 1 crank)\u003c\/li\u003e\n\n\u003cli\u003e Attachment: 4-arm spider\u003c\/li\u003e\n\n\u003cli\u003e Number of teeth: 38, 40 or 42 teeth\u003c\/li\u003e\n\n\u003cli\u003e Compatibility cranks: SRAM Apex 1 crank\u003c\/li\u003e\n\n\u003cli\u003e Chain compatibility: 10-, 11-speed\u003c\/li\u003e\n\n\u003cli\u003e Chainline: 45.5mm\u003c\/li\u003e\n\n\u003cli\u003e Offset: Default\u003c\/li\u003e\n\n\u003cli\u003e Adjustment options: none\u003c\/li\u003e\n\n\u003cli\u003e Range (ovalization): 10.2 - 14.4% (optimized for each chainring size)\u003c\/li\u003e\n\n\u003cli\u003e Timing (force application): 110.5 - 116.3° after TDC (OT) (optimized for each chainring size)\u003c\/li\u003e\n\n\u003cli\u003e Color: Black\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n","brand":"Absolute Black","offers":[{"title":"40 Zähne","offer_id":47310976287060,"sku":"56221-40","price":79.99,"currency_code":"EUR","in_stock":false},{"title":"42 Zähne","offer_id":47310976319828,"sku":"56221-42","price":79.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/9148\/0660\/products\/Absolute-Black-APEX1-oval_0146f2ae-1d2d-4486-9a55-894b738e6b69.jpg?v=1701992259","url":"https:\/\/smpirts.com\/en\/products\/absoluteblack-sram-apex1-oval-narrow-wide-kettenblatt-schwarz","provider":"SMParts","version":"1.0","type":"link"}
