# 將 DURA 與電子變速（SHIMANO、SRAM）配對
DURA 支援與**SRAM** Force 和**SHIMANO** Di2 RD-R8150 配對。目前 SHIMANO 只能透過 BLE 進行配對。
若要將電子變速與 DURA 配對，請依照下列步驟操作：
1. 從主選單中，捲動至系統 > 附件 > 新增附件。
2. 確保您的電子變速處於配對模式。
3. DURA 將開始搜尋附近的設備。
4. 當您的電子變速出現時，在 DURA 螢幕上選擇它以完成配對過程。
當與電子變速配對時，DURA 可以顯示以下資料欄位（了解[如何自訂資料欄位](https://support.coros.com/hc/en-us/articles/26920689006228-Customize-Activity-Data-Pages-on-DURA)）：
* 齒輪（當前的前後齒輪）
* Gear Combo（目前的齒輪組合）
* 齒輪比（自行車前後齒輪的齒數；該數據也將顯示在活動摘要中）
### 如何檢查電子變速桿的電池？
與 DURA 配對後，轉至配件清單 > 選擇配對的變速 > 選擇電池。 *注意：此功能將在未來的韌體更新中提供。*
