Power meters measure what actually matters: how many watts you're pushing through the cranks. Heart rate tells you how hard your body is working, but power tells you what the bike is receiving. The SRAM Rival AXS Power Meter crankset integrates strain gauges into the spider, measuring left and right leg contributions independently for true dual-sided power data.

The DUB spindle system runs on oversized aluminum, compatible with DUB bottom brackets across BSA, PF30, BB30, and T47 shells. You'll need the matching DUB bottom bracket for your frame, but once installed, the spindle-to-bearing interface stays consistent regardless of frame standard. The carbon crank arms keep weight reasonable for a power-equipped crankset while handling the load demands of repeated sprint efforts.

Chainring options span road racing and gravel setups. The 48/35T combination covers traditional road gearing, while the 46/33T works for mixed terrain where you need lower gears without running a full compact. Both use SRAM's 12-speed X-Range chainring design, which pairs specifically with Flat Top chains. You cannot run a standard 11-speed chain on these rings—the tooth profile is different.... Read More
