Eagle S100 PowerSpline Crankset

The SRAM Eagle S100 crankset mounts to SRAM's PowerSpline bottom bracket standard, the older splined interface that predates DUB and remains incompatible with it. Riders running a DUB shell need a bottom bracket swap before this crank works, while a PowerSpline shell takes the S100 without further changes. Confirming which standard a frame uses before ordering saves a return.

What Our Gearhead® Experts Are Saying:

"Running the 155mm arms on a small-frame build cut pedal strikes through rock gardens without touching bottom bracket height, since the reduction comes entirely from arm length, not geometry. That's the case for going shorter on tight, low-clearance terrain."
