The Eagle S100 B1 combines aluminum arms with a 32T steel ring in a 1×12 configuration. This black 160mm version uses SRAM’s PowerSpline interface, a three-bolt direct mount and the selected 49mm chainline.
PowerSpline 118/73 bottom-bracket use is specified. Check that requirement against the actual frame before choosing the separately sold bottom bracket. The PowerSpline interface differs from DUB even within the Eagle crank range.
