The Double Diamant finish combines a scratched surface with a frontal machined one that is smooth and shiny.

The combination of these 2 different textures gives a sophisticated and technical look to the crank arm and also enhances its distinct design outlines.
The cold-forging process used by Miranda, the high-quality aluminium and a process that allows to eliminate the weak spots and distribute the applied. loads in an integrated way is what makes Delta Double Diamant crank highly resistant to fatigue and high impact tensions.
