- 选择牙盘、飞轮、内变速、轮胎等型号以及踏频，实时计算出齿比、速比、车速等参数并绘制曲线。
- 勾选”踏频/车速“中的”车速“，可输入车速，反算所需踏频。
- 点击”添加当前曲线“记录当前的曲线用于对比，可添加多条曲线。
- 点击”导出文件“导出当前配置和计算结果，导出的文件需使用Excel打开查看。
- 对于没有飞轮变速只有内变速的情况，在飞轮处选”1s/内变“，并设置内变速上飞轮的齿数。
- 右键点击曲线图可选择当前曲线显示模式。
- 在计算结果表格中选择任意一行，可查看所对应的档位信息和图像上的位置。
- Select the crankset, Cassette Sprockets, Internal Hub, tires models and cadence, the gear ratio, speed ratio and other parameters will be calculated in real-time and the curve will be drawn automatically.
- Check "speed" in the group box "cadence / speed", the reverse calculation from speed to cadence will be available.
- Click "Add current curve" button to add current curve to the chart for comparison, multiple curves can be added.
- Click "Export File" to export current configuration and calculation results, the exported file can be opened with Excel.
- For Internal Hub only cases, select "1s / Internal Hub" in the Cassette Sprockets box and set the number of teeth on cassette.
- Right-click on the chart to select the display mode of the current curve.
- Select any row in the results table, the corresponding gears and point on the curve will be highlighted.
