描述
產品概述
ROTOR Q-Rings 110BCD 橢圓齒盤專為緊湊型曲柄（Compact Cranks）設計，基於一個核心概念：若你能更有效地利用最大出力、同時縮短踩踏迴轉中「死點」所耗費的時間，就能踩得更有效率。Q-Rings 以細微卻高效的 10% 橢圓率，結合定位因子（Orientation Factor），帶來顯著提升的踩踏表現。你可從 5 個最佳齒盤位置（OCP） 中選擇，微調出最適合自己的騎乘體驗，以更少的疲勞騎得更遠、更快。
主要特點
-
10% 橢圓率：細微但高效的橢圓設計，改善踩踏效率
-
OCP 最佳齒盤位置：5 個定位點（50/34T 為 4 個），可微調橢圓角度
-
100% CNC 加工：7075-T6 鋁合金材質，輕量且耐用
-
鋼製變速銷：確保精準可靠的變速性能
-
廣泛相容：適用於所有 9、10、11 速變速系統

Product Overview
ROTOR Q-Rings 110BCD oval chainrings are designed for compact cranks, based on the concept that you can pedal more efficiently if you can take greater advantage of your maximum power effort while lessening the time spent in the dead spots of a pedal rotation. Q-Rings’ subtle but efficient 10% ovality combined with the orientation factor yields an improved pedal stroke marked by performance. Choose from 5 Optimum Chainring Positions (OCP) to fine-tune your improved riding experience and go further and faster with less fatigue.
Key Features
-
10% Ovality: Subtle yet efficient oval design for improved pedaling efficiency
-
OCP (Optimum Chainring Positions): 5 positioning points (4 points for 50/34T) for fine-tuning oval orientation
-
100% CNC-Machined: 7075-T6 aluminium alloy, lightweight and durable
-
Steel Shifting Pins: Ensures precise and reliable shifting performance
-
Wide Compatibility: Designed to work with all 9, 10, and 11-speed groupsets

Some cranks require specific Q-Rings — please confirm your crank model before purchase
Notes
-
This is an Outer chainring — must be paired with a matching inner ring.
-
Oval chainrings must be installed with the OCP positioning points aligned for optimal pedaling performance.
-
Some cranks (e.g., certain power meters or proprietary spiders) may require a specific Q-Rings version.
