The oval profile varies the effective gear ratio through each pedal stroke — easing tension through the dead spot and increasing leverage at the power phase — which is designed to reduce muscular fatigue on long rides and hard efforts alike.\u003c\/p\u003e\n\n\u003cp\u003eRotor's Q-Rings use an \u003cstrong\u003eOptimum Chainring Position\u003c\/strong\u003e (OCP) system, allowing you to rotate the ring and dial in the oval orientation to match your individual pedaling style. Whether you're building up a training wheelset or refreshing a race bike, the Q-Ring slots into any standard 4-bolt Shimano road crankset and works with your existing drivetrain.\u003c\/p\u003e\n\n\u003ch3\u003eRotor Q-Ring Outer Chainring Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eCompatibility: 4-bolt Shimano road cranks\u003c\/li\u003e\n  \u003cli\u003eAvailable sizes: 46t, 50t, 52t, 53t\u003c\/li\u003e\n  \u003cli\u003eRing shape: Oval (Q-Ring profile)\u003c\/li\u003e\n  \u003cli\u003eFinish: Black\u003c\/li\u003e\n  \u003cli\u003eAdjustable OCP (Optimum Chainring Position) mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Rotor","offers":[{"title":"4bcd \/ 46t \/ Black","offer_id":43594826154028,"sku":"C01-020-15010-0","price":109.99,"currency_code":"USD","in_stock":true},{"title":"4bcd \/ 50t \/ Black","offer_id":43594826186796,"sku":"C01-020-11020-0","price":109.99,"currency_code":"USD","in_stock":true},{"title":"4bcd \/ 52t \/ Black","offer_id":43594826219564,"sku":"C01-020-09020-0","price":109.99,"currency_code":"USD","in_stock":true},{"title":"4bcd \/ 53t \/ Black","offer_id":43594826285100,"sku":"C01-020-08020-0","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/rotor-q-ring-outer-chainring-for-4-bolt-shimano-cranks-6061849.jpg?v=1771294570","url":"https:\/\/ricycles.com\/products\/rotor-q-ring-outer-chainring-for-4-bolt-shimano-cranks","provider":"RA Cycles","version":"1.0","type":"link"}
