SRM CYBREI Carbon Crank Arms

The SRM CYBREI Carbon Crank Arms are some of the lightest crank arms in the world. Made specifically for the SRM Origin power meter, these crank arms weigh only 331 grams, including the spindle. While they are extremely light, these crank arms are also some of the stiffest available. They have passed all UCI certifications and use an aluminum DUB spindle for maximum bottom bracket versatility. However, they also can be used with 30 mm bottom brackets with the the included 30 mm adapter.

Please note the DUB spindle is not removable from this crankset.
