The Shimano lineup spans 105, Ultegra, Dura-Ace, and GRX for gravel and XT for mountain. SRAM covers Rival through Red AXS, with multiple DUB-standard options including integrated power meters. Campagnolo is represented with Super Record 13 WRL — with and without power — and Chorus 12-speed. SRM's Origin and Science PM9 cranksets are dedicated power meter systems built around THM and Campagnolo interfaces, with a precision measurement reputation that predates most other brands in this category.
