SRAM Rival XPLR Wide Power Meter 1x13-speed gravel bike crankset

The aluminium cranks have been made lighter without compromising the accuracy of power measurement. The power unit integrated into the axle, which is both lightweight and reliable, fits perfectly into the redesigned cranks to provide accurate and useful data. The new direct-mount chainrings combine lightness, stiffness and a sleek design.

This axle-based unit measures power on the left side to calculate total power. It boasts an exceptional battery life of over 400 hours thanks to a user-replaceable AAA lithium battery. The DUB bottom bracket ensures durability and ease of use. Waterproof to IPX7 standard (submersion up to 1 metre for 30 minutes), this system adds less than 40 grams compared to a standard crankset.

SRAM X-SYNC technology, with its wide and narrow teeth, offers optimal chain control, whilst the extended chainline ensures perfect compatibility with Full Mount rear derailleurs.
