H&H 獨創設計，專為 Brompton 外2速車款 開發，採用 一體式護盤雙盤齒片，可直接安裝於 原廠 BCD130mm 曲柄。提供 54/33T 與 50/33T 高齒差配置，讓 Brompton 不僅適合城市騎行，也能挑戰丘陵或登山路段。由於齒差較大，無法搭配前變速器，需透過停車進行大小盤切換，但同時保留了小布簡潔優雅的風格。材質使用 7075 鋁合金，重量僅 118g (50/33T) / 130g (54/33T)。
Chain-Guard Integrated with Double Chainring
Exclusively designed by H&H for Brompton external 2-speed models, this one-piece double chainring with chain guard directly mounts to the OEM BCD130mm crankset. Available in 54/33T and 50/33T configurations, it transforms Brompton from an urban commuter into a bike capable of tackling climbs and scenic routes. Due to the wide gear difference, it does not support a front derailleur and requires manual switching while stationary, preserving Brompton’s minimalist style. Constructed from 7075 aluminum alloy, it weighs only 118g (50/33T) / 130g (54/33T).
