ROTOR Oval Chainrings (Q-ring) DM 1x 直裝式單片楕圓片

描述

ROTOR Q-Rings DM 1x 直裝式橢圓齒盤是一款專為 1x 單盤系統設計的一體式橢圓齒盤，採用直裝式（Direct Mount）設計，無需盤爪與螺絲即可直接安裝於相容的 ROTOR 曲柄上。相較於傳統「齒盤＋盤爪＋螺絲」的組合，一體式設計可節省約 40 克 重量，同時提升剛性與動力傳輸效率。

主要特點

12.5% 橢圓率
Q-Rings 的橢圓設計能有效縮短踩踏過程中的「死點」時間，延長高效出力區間，讓踩踏更平順、更省力，同時減少膝關節壓力。

直裝式設計
一體式 CNC 加工，直接鎖附於曲柄，省去盤爪與螺絲，簡化外觀、減輕重量，同時提升整體剛性。

OCP 最佳齒盤位置
專利 OCP 系統可依個人踩踏風格，以 1 度為單位微調橢圓角度，精準匹配最適合的出力位置。

Universal Tooth® 技術
齒型設計相容於 10、11、12、13 速鏈條，包含 Shimano、SRAM 等主流系統，變速精準、安靜，減少落鏈與磨損。

7075-T6 鋁合金
100% CNC 精密加工，輕量、高強度、耐用。

Product Overview

The ROTOR Q-Rings DM 1x Direct Mount Oval Chainring is a one-piece oval chainring designed for 1x single-chainring systems. With Direct Mount technology, it attaches directly to compatible ROTOR cranks without a spider or extra bolts. Compared to a standard ring + spider + bolts combination, the one-piece design saves approximately 40 grams while improving stiffness and power transfer efficiency.

Key Features

12.5% Ovality
The Q-Rings oval design effectively reduces time spent in the “dead spots” of the pedal rotation, extending the power phase for smoother, more efficient pedaling and reduced knee stress.

Direct Mount Design
One-piece CNC-machined construction attaches directly to the crank, eliminating the spider and bolts for a cleaner, lighter setup with enhanced overall stiffness.

OCP (Optimum Chainring Position)
The patented OCP system allows 1-degree incremental adjustment of the oval orientation to precisely match your pedaling style.

Universal Tooth® Technology
Tooth profile compatible with 10, 11, 12, and 13-speed chains, including Shimano, SRAM, and other major systems, delivering precise, quiet shifting with reduced chain drop and wear.

7075-T6 Aluminium
100% CNC-machined, lightweight, high-strength, and durable.
