描述
產品概述
SHIMANO FC-R9200 DURA-ACE 齒片是 Dura-Ace R9200 2×12 速公路曲柄組的專用替換齒片，同時兼容 FC-R9200-P 功率計版本。採用 4 臂非對稱 110mm BCD 設計，外片以 HOLLOWGLIDE 中空結構配合鋁碳複合材料製成，在減輕重量的同時維持高剛性與精準變速性能。
主要特點
-
HOLLOWGLIDE 中空結構：外片採用中空成型技術，兼顧輕量化與高剛性，提升動力傳輸效率與變速精準度。
-
鋁碳複合材料：50T / 52T / 54T 外片使用鋁合金與碳纖維增強塑料（CFRP）複合材質，34T / 36T / 40T 內片為純鋁合金。
-
陽極氧化處理：所有齒片均經過陽極氧化，耐用且美觀。
-
精準配對設計：齒片有特定 Type 編碼（NK / NH / NJ），必須同類型配對使用以確保最佳變速性能。

Product Overview
The SHIMANO FC-R9200 DURA-ACE chainring is a replacement ring for the Dura-Ace R9200 2×12-speed road crankset, also compatible with the FC-R9200-P power meter version. Featuring a 4-arm asymmetrical 110mm BCD design, the outer ring uses HOLLOWGLIDE hollow construction with an aluminium-CFRP composite to reduce weight while maintaining high stiffness and precise shifting performance.
Key Features
-
HOLLOWGLIDE Construction: Hollow-formed outer ring balances lightweight and high rigidity for efficient power transfer and shifting precision.
-
Aluminium-CFRP Composite: 50T / 52T / 54T outer rings use aluminium with carbon fiber reinforced plastic (CFRP); 34T / 36T / 40T inner rings are pure aluminium.
-
Anodized Finish: All chainrings feature an anodized finish for durability and aesthetics.
-
Precision Pairing: Chainrings have specific Type codes (NK / NH / NJ) and must be paired with the same type for optimal shifting performance.
