It features a 50\/34 tooth double chainring setup on a Campy 121\/88 Asymmetrical BCD. The crankset is constructed entirely of unidirectional carbon fiber, incorporating the Ultra-Torque locking system with a steel axle to efficiently transfer pedaling power to the drivetrain. The reworked aluminum chainrings ensure efficient power transfer and smooth shifting, including with extreme cross-chaining, thanks to symmetrical teeth on the inner chainring. High-quality bearings provide smooth operation, a hallmark of Campagnolo components. This crankset is compatible with 135\/142 road disc hubs on frames with chainstays both shorter and longer than 415 mm and includes a 9\/16\" pedal spindle. Bottom bracket is sold separately. The crankset is finished in carbon color.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv id=\"seqbpfeatures\"\u003e\u003cul\u003e\n\u003cli\u003eCampagnolo Super Record S Wireless crankset features a 2x12-speed drivetrain with 50\/34t aluminum chainrings. \u003c\/li\u003e\n\u003cli\u003eConstructed from unidirectional carbon fiber for lightweight and stiffness. \u003c\/li\u003e\n\u003cli\u003eUses Ultra-Torque steel axle for efficient power transfer and durability. \u003c\/li\u003e\n\u003cli\u003eOptimized tooth design on chainrings ensures smooth, precise shifting and cross-chaining. \u003c\/li\u003e\n\u003cli\u003eCompatible with 135\/142 road disc hubs and fits 172.5mm crank length for road cycling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Campagnolo","offers":[{"title":"Default Title","offer_id":42447205466179,"sku":"CKST3581","price":676.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1608\/6187\/files\/CK1439_885ebc12-2203-4a49-878c-0556404eb665.jpg?v=1773403842","url":"https:\/\/tecopecosafe.com\/products\/campagnolo-super-record-s-wireless-crankset-172-5-mm-double-12-speed-ckst3581-bicycle-crankset","provider":"365 Cycles","version":"1.0","type":"link"}
