Power data transforms how you train, but most gravel rides don't follow the predictable patterns of road cycling. You're grinding up fire roads, punching through loose corners, and occasionally shouldering the bike over obstacles. The SRAM Force XPLR AXS E1 Power Meter puts Quarq's DZero strain gauge technology into a crankset designed specifically for mixed-terrain riding, measuring your actual power output regardless of what the trail throws at you.

The DZero power meter spider sits at the heart of this system, positioned between the crank arms and chainring where it captures total power from both legs. SRAM claims accuracy within 1.5 percent, which holds up whether you're seated and spinning or standing and mashing. The rechargeable battery eliminates coin cell replacements—you plug in the magnetic charger, top it off in about an hour, and get roughly 200 hours of ride time before the next charge. That's a full season of weekend adventures without thinking about battery life.

Carbon crank arms keep weight competitive while the DUB spindle interface works with SRAM's corresponding bottom bracket standards. You'll need to match your frame's shell width and type, but DUB brackets cover everything from BSA threaded to PressFit 30 and PF86. The single chainring setup accepts 40T or 44T direct-mount rings depending on your terrain and gearing preferences—lower for steep backcountry climbs, higher for faster gravel roads.... Read More
