What sets the SRAM Force XPLR Power Meter apart from dual-sided?

The SRAM Force XPLR AXS power meter lives inside the DUB spindle rather than in the spider or the chainrings. It uses Quarq measurement to read your left leg and doubles that figure for total watts, and that is the real trade in this crankset: a single-sided reading in exchange for a lighter package and far longer run time than a spider unit. Because the sensor sits in the spindle, the power meter does not care which chainring you run, so swapping ring sizes leaves the measurement untouched. Readings hold to within +/-1.5%.

The crankset pairs carbon arms with a 42t direct mount X-SYNC chainring and works with 12 and 13-speed XPLR drivetrains. It uses a DUB Wide spindle, so it needs a DUB Wide bottom bracket matched to your frame shell, sold separately. SRAM's fitment rule matters here: XPLR cranks belong on frames with chainstays of 415 mm and longer, and road cranks on frames at 414 mm and below. The AAA lithium battery is user-replaceable and good for over 400 hours of riding.
