CEMA 12-14T 陶瓷大導輪是公路車與山地車傳動系統改裝的熱門高性價比選擇。這款改裝導輪採用上導輪 12T、下導輪 14T 的加大設計（原廠通常為上下 11T），其核心優勢在於無需更換後變速器導輪支架（俗稱大雞腿導輪架）與鏈條，即可直接拆螺絲直上安裝。
🛠️ 核心規格與特點
  • 齒數配置：上 12T / 下 14T 窄寬正負齒設計，鏈條咬合更穩定。
  • 導輪材質：CNC 精密加工的 7075 T6 鋁合金，剛性高且大幅減少塑料導輪的形變。
  • 培林等級：提供全陶瓷培林（Full Ceramic）、混合陶瓷培林及不鏽鋼培林。全陶瓷版本連培林保持架都採用陶瓷，傳動阻力極低。
  • 主要效益：透過增大導輪直徑減小鏈條曲折角度，有效降低摩擦阻力、提升變速順暢度，並達到省力（瓦數）的效果。
