SRAM Force can support a power meter when the setup uses a SRAM AXS crankset, and one available option is the SRAM Force/Red AXS Power Meter Spider. This upgrade replaces your current spider on the drive-side crankarm, so you can add power measurement without swapping the entire crankset. It is a clean move for riders who want deeper ride data while keeping the rest of their AXS setup rolling.
The install is straightforward: remove the eight T20 Torx bolts holding the existing spider, then bolt this unit in place. Once installed, it starts delivering key ride metrics including cadence and wattage. It also measures left and right leg power balance separately, which is useful for training, fit refinement, and spotting asymmetries when the ride gets punchy.
This spider uses a 107mm bolt circle diameter and works with both 1x and 2x drivetrains, giving it solid flexibility for current builds and future changes. Because it is AXS enabled, it connects with SRAM's app so you can check battery status and run firmware updates. Ride data can be sent to a smartphone, tablet, or head unit through Bluetooth Low Energy or ANT+. Power readings are accurate to within +/-1.5% and are not affected by changing climate conditions during the ride.
Adding a spider-based meter changes more than the numbers on your head unit. It gives you a clearer picture of how you're riding, especially when pacing long efforts, dialing repeatable intervals, or keeping the first hour from turning into a hero move you regret later. With cadence and wattage on tap, effort becomes measurable instead of guesswork.
The biggest performance win here is the combination of power measurement and left-right balance tracking. Separate leg balance data can help you notice how you produce power under fatigue, during seated efforts, or when you're fine-tuning position on the bike. That kind of insight is gold for riders who like their training precise and their setup intentional.
Because this unit is part of the AXS ecosystem, it fits into a modern electronic build without adding unnecessary drama. The app connection lets you monitor battery status and handle firmware updates, while Bluetooth Low Energy and ANT+ make it easy to send ride data to the device you already use. Translation: less fiddling in the garage, more time turning pedals.
If you're riding SRAM Force and want power without replacing the whole crank, this style of upgrade makes a lot of sense. The key fit detail is simple: this option is designed to upgrade a SRAM AXS crankset. If that matches your bike, you're looking at a direct path to power data through a spider swap rather than a full crank overhaul.
Next, think about your drivetrain now and where it may go later. The 107mm bolt circle diameter works with both 1x and 2x configurations, which is handy if your build priorities change between all-road, race, or mixed-terrain duty. That versatility keeps the setup from boxing you in.
This option fits riders who want actionable metrics and clean integration. It is especially useful if you:
Confirm that your crankset is part of the SRAM AXS family and that a spider-based replacement is the upgrade path you want. If you want a second set of eyes before committing, a Gearhead® Expert can help sort through compatibility so your next ride starts with power, not guesswork.
Power meter shopping can get weirdly complicated in a hurry—bolt patterns, drivetrain formats, app ecosystems, head unit compatibility. That's exactly where Backcountry comes in. We keep the focus on the gear and how it works on the bike, so you can spend less time decoding spec sheets and more time building a setup that rides the way you want.
When questions get specific, a Gearhead® Expert can help you think through fit, compatibility, and whether a spider-based option matches your current crank. No gatekeeping, no jargon avalanche—just solid guidance from people who are genuinely into the details.
If you're tuning a bike for stronger training feedback and cleaner integration, this is the kind of upgrade we get stoked about: purposeful, measurable, and ready to roll with the rest of your AXS system.
