As power meters become more smaller and cheaper, they're becoming close to standard issue for avid gravel riders. The SRAM Rival 1 AXS 12-Speed Wide Power Meter Crankset adds less than 40g to SRAM's excellent gravel 1x crankset, all while pumping out accurate and dependable left-crank wattage numbers. This integrated design is clean and unobtrusive to the point where even a rider who's not looking for a power meter could run it without knowing.
