Power2Max NG Eco SRAM 110bcd Spider Info
The Power2Max NG Eco SRAM 110bcd Spider is a spider-based power meter that swaps in for the stock spider on compatible SRAM cranksets, turning a crank you already own into a power-measuring one. It's built for SRAM's 3-bolt cranks — Force 1, Rival 1, Force 22, Rival 22, and S900 — in the 110bcd fitment, and at roughly 160 grams it adds negligible weight to the drivetrain. Because it measures torque at the spider rather than independently at each crank arm, it reports total power along with left-right balance and pedal smoothness, giving you the training metrics that matter without the cost of a true dual-sided system.
Accuracy is rated at +/-2%, with a paid upgrade path to +/-1% for riders who want tighter precision for structured training or racing. Data goes out over both ANT+ and Bluetooth, so it pairs with a head unit, a smart trainer, or a phone app without extra hardware, and the unit includes temperature compensation to keep readings consistent as conditions change through a ride. Power comes from a user-replaceable CR2450 coin-cell battery rated around 300 hours, which means no charging cables to track down before a big ride — just a battery swap every few months of regular riding.
The NG Eco name reflects where this sits in Power2max's lineup: it's the accessible entry point into their spider-based power meters, built around the same core measurement approach as their premium NG line but with a coin-cell battery instead of rechargeable and a wider stock accuracy tolerance. It's backed by a 2-year warranty, upgradable to 5 years, and rated water-resistant for riding in the rain. For a rider with a compatible SRAM crank who wants reliable, ANT+/Bluetooth power data without paying for a rechargeable battery or the tightest possible accuracy spec, the NG Eco is a straightforward way to start training with power.
