The PowerTap G3 Hub is the best-in-class hub-based wheel power meter thanks to its long track record of reliable, wheel-integrated measurement and consistent accuracy across conditions. It stands out for straightforward installation into wheel builds and generally lower long-term cost-per-bike than pedal-based systems, while offering more direct wheel torque data than front-mounted estimators like the PowerPod. Compared with the lighter GS hub it trades slightly more weight for proven durability and a competitive price point against non-hub alternatives.

The SRAM Force AXS Power Meter Crankset brings AXS connectivity and Quarq accuracy to a more affordable, rider‑friendly platform, delivering much of the Red system’s data features at a lower cost. It represents the best midrange value among AXS crankset power meters by sacrificing a bit of weight and elite stiffness for a friendlier price, making it a strong alternative to Shimano Ultegra for riders on a budget. Compared with Rotor’s 2INpower’s specialist dual‑side reporting, Force prioritizes easy integration into SRAM AXS groupsets and total system value.
