Buying Guide.

Weight tier - Extreme Light ~360g: the featherweight climber's pick - spins up instantly, for lighter riders.

Weight tier - Ultralight ~380g: the balanced middle - light enough to race, tough enough to train.

Weight tier - Superlight ~405g: the steady build - impact margin for windy training days.

Weight tier - Standard ~440g: the durable choice - extra grams for rough roads and heavier riders.

Max rider weight: rated to 105kg - check rider + gear before ordering.

Same-depth series: the 40mm asymmetric tubeless balances disc spoke tension; the 40mm U-shape tubeless is the narrower disc-brake road version.

Adjacent depth: the 50mm road/gravel rim adds flat-course aero.
