Shifting Operation 变速操作
Press the upshift button to shift the rear derailleur outward toward the smallest
cassette cog. Hold the button continuously for multiple consecutive shifts. Each tap of
the shift lever triggers one flash of the controller LED; continuous tapping results in
continuous LED flashing.
Press the downshift button to shift the rear derailleur inward toward the largest
cassette cog. Hold the button continuously for multiple consecutive shifts. Each tap of
the shift lever triggers one flash of the controller LED; continuous tapping results in
continuous LED flashing.
按下升档按键，后拨链器向外侧最小飞轮齿片移动；长按按键可连续多档升档。每拨
动一次指拨拨杆，指拨 LED 指示灯闪烁一次；持续拨动拨杆，指示灯持续闪烁。
连续变档功能可使用 app 关闭
按下降档按键，后拨链器向内侧最大飞轮齿片移动；长按按键可连续多档降档。每拨
动一次指拨拨杆，指拨 LED 指示灯闪烁一次；持续拨动拨杆，指示灯持续闪烁。
Rear Derailleur Installation 后拨链器安装
Use a 5 mm hex wrench to secure the rear derailleur to the frame hanger. Thread the
matching chain sequentially through the two guide rollers of the derailleur. Optimal
shifting performance is achieved when the gap between the inner flat surface of the
chainstay and the outer side of the smallest cassette cog measures 4–6 mm.
使用 5mm 内六角扳手将后拨链器固定于车架尾勾，将适配链条依次穿过后拨两组导轮。
后下叉内侧平面与飞轮最小齿片外侧间距保持 4–6mm 时，后拨变速性能达到最佳。
Precautions 安装注意事项
1. Mounting bolt tightening torque: 8.0–10.0 N·m
2. Improper tightening may cause the following faults: - Deformation of the hanger
mounting hole; - Inability to assemble or disassemble components; - Degraded
shifting performance
3.
Do not apply grease to the mounting bolt or frame hanger threaded hole.
4. Use of mismatched chain specifications will reduce shifting reliability, and may
cause equipment failure in severe cases.
5. This rear derailleur is compatible with 28T–36T cassettes.
1. 安装螺栓锁紧扭矩：8.0–10.0 N·m；
2. 锁紧力度不当会引发以下故障：- 尾勾安装孔变形；- 零部件无法正常拆装；- 变速
手感变差、变速不准；
3. 禁止在安装螺栓与尾勾螺纹孔涂抹润滑脂；
4. 使用规格不匹配的链条会降低变速稳定性，严重时造成设备故障；
5.
本公司所有变速器适配的最低速别链条为
10
链条（链条厚度最大为：
xxx
）
6. 本后拨链器适配的飞轮需参考下面规格列表。

comfortable operating angle, then tighten the mounting nut.
使用
2.5mm
内六角扳手将指拨固定在车把上，旋转至舒适操作角度后锁紧安装螺母。
Precautions 安装注意事项
1. Mounting bolt tightening torque: 2.0–4.0 N·m
2. Do not apply grease to the mounting bolt or inner surface of the lock ring.
1. 安装螺栓锁紧扭矩：2.0–4.0 N·m；
2. 禁止在安装螺栓、锁环内侧涂抹润滑脂。
Derailleur Adjustments 变速器微调设置
1. Single-Stage Fine Adjustment 单档微调
Press and hold the coding button on the side of the shift lever. Once the indicator
light flashes blue, the unit enters single-step fine adjustment mode. Users may make
tiny step-by-step adjustments to the rear derailleur position via the dedicated mobile
app or handlebar shift lever. Continue fine-tuning until center A of the rear derailleur
guide roller is perfectly aligned with the center of the smallest cassette cog to
complete single-step fine adjustment.
请优先使用整体微调，将大部分档位对齐后针对个别变速异常档位再使用单档微调。
长按指拨侧边拨码按键，指示灯蓝色闪烁即进入单档微调模式；可通过配套手机 APP
或车把指拨逐档微量调节后拨位置；持续微调，直至后拨导轮 A 中心点与飞轮最小齿
盘中心完全对齐，即完成单档微调。
2. Overall Fine Adjustment 整体微调
Press and hold the coding button on the side of the shift lever. A steady blue light
indicates entry into overall fine adjustment mode. Synchronously fine-tune all gears
via the supporting APP or handlebar shift lever. Continue adjusting until the center
point A of the rear derailleur guide pulley is precisely aligned with the center of every
cassette cog. The overall fine adjustment is finished when shifting runs smoothly on
all gears with no chain rub.
长按指拨侧边功能按键，蓝灯常亮即为进入整体微调模式；可通过配套 APP 或车把指
拨同步微调全部档位；持续调节，让后拨导轮 A 中心点与飞轮所有齿盘中心精准对齐，
全部档位变速顺畅、无蹭链，整体微调完成。个别档位无法对齐时可进入单档微调进
行调节。
3. Supplementary Operation Tips 补充操作提示
Press and hold the coding button after fine-tuning. The blue light will turn off,
parameters will be saved automatically and the unit exits fine adjustment mode.
Single-step fine adjustment is used for chain rub on the smallest cassette cog and
abnormal noise in high-speed gears. Overall fine adjustment applies to chain rub
across all gears and overall shifting offset. It is recommended to adjust only 1 click
per fine-tune operation. Do not make large adjustments at a time to prevent chain
drop.
微调完成后长按拨码按键，蓝灯熄灭即自动保存参数并退出微调模式；单档微调适用
于最小飞轮蹭链、高速档位异响问题；整体微调用于全档位蹭链、整体变速位置偏移
场景；每次微调建议仅调节 1 小格，切勿一次性大幅调节，防止链条脱落。

Maintenance 保养维护
Regularly clean the sediment and oil stains on the surfaces of the rear derailleur,
guide rollers and cassette to keep the shifting structure clean and smooth. Regularly
check the battery level, the tightness of safety latches and screw torque to avoid
loose parts and shifting jamming after long-term use. Remove the battery for
separate storage if the equipment is not in use for a long time to extend the service
life of the device.
定期清理后拨链器、导轮及飞轮表面泥沙、油污，保持变速结构清洁顺畅；定期检查
电池电量、锁扣紧固状态及螺丝扭矩，避免长期使用出现松动、变速卡顿；长期不使
用设备时，请取出电池单独存放，延长设备使用寿命。
