Are the wider gearing Force eTap AXS 43/30 cranksets compatible with the same bottom brackets as SRAM’s other DUB road cranksets?

No. The wide cranksets require additional spacers outside of the bottom bracket bearings. When buying bottom bracket bearings for a wide crankset, look for a “WIDE” suffix in the product description (e.g. BB DUB BSA 68 ROAD WIDE) to ensure you get the model

that comes with the correct spacers.
