STEP 1: INSTALL
The spider-based power meters attach to AXS cranksets using a simple 8-bolt interface. To install one, remove your driveside crank arm using a hex wrench long enough to apply the 54 Nm of force required to back out the fixing bolt. Then remove the eight Torx T20 bolts that attach the crank spider or chainring assembly to the crank. If applicable, we recommend removing the chainrings using a Torx T30 wrench before removing the eight spider fixing bolts.
