Environmental Product Declaration

Environmental data.
Independently verified.

The Delta crank family is represented in Miranda’s multi-product Environmental Product Declaration for forged aluminium cranks. The declaration and data were independently verified by SGS ICS Italia.

Conservative, worst-case results across the included products. Explore the full declaration for its product scope, reference configurations and environmental indicators.

Estimated impact · one crank arm

1.91 kg CO₂e per crank arm

Based on one 245 g catalogue reference crank arm.

Mass-based estimate using the EPD’s conservative factor. Arm weight depends on the selected configuration.

How this estimate is calculated

7.78 kg CO₂e/kg × 0.245 kg = 1.91 kg CO₂e per crank arm.

The displayed estimate is for one crank arm at the catalogue’s reference mass. This is an illustrative conversion of the multi-product EPD’s conservative GWP-total factor, rather than an independently verified result for this individual variant. Left/right geometry, length, interface and finish can change the actual arm weight.

Catalogue weight note: crank (ISIS 170/Q:16) without bolt.

The EPD declares 1 kg of forged aluminium cranks with the referenced packaging included in the assessment. It reports the highest result for each indicator across its included products; different indicators can therefore represent different products. Primary data refer to 2024.

The study is cradle-to-gate. Customer distribution, use and end-of-life stages are outside this boundary. The declaration concerns forged aluminium cranks; it does not establish the footprint of a complete crankset with chainrings, spindle, spider and additional hardware.

Published families: Delta, Kapa/Kappa, Sigma, Epsilon, Classic, PSI, Helius, Virage, Kies and Mythos (Mithos in the catalogue). See the declaration’s product list and reference configurations, and contact Miranda to confirm applicability for your specification.
