Why We Like The Rival 1x 12-Speed Crankset

For a sophisticated design and consistent chain control over long periods of pedaling, we'd recommend the Rival 1x 12-Speed Crankset. It's SRAM's offering for cyclists in favor of a more simple and lightweight 1x setup, which allows us to run a tidy crankset. SRAM utilizes aluminum for the construction of the crank arms, which reduces weight while maintaining stiffness and strength for our benefit. We're also seeing the aluminum DUB spindle, which adds durability to the bottom bracket bearings, plus broader frame compatibility. A wide, 47.5-millimeter crankset fits the largest gravel tires, and the longer DUB crank spindle accommodates both road and MTB width frame bottom bracket standards for cross-compatibility.

Great cranks!

I've put it through the wringer

This was delivered in record time! These 165 mm cranks were more gentle on my hips, enabling me to go on longer bike rides. The folks at competitive cyclists are very knowledgeable and chatting with them helped me make the right order that were compatible with my SRAM set up.
