Chainrings production background:
The material is CNC machined 5 mm wide 7075-T6 aluminium plate!
The codename ’354 refers to 3 mm tooth width, 5 mm outer ring width, and 4 mm inner ring width. It’s a perfect combination of minimalised weight and maximum strength which provides a unique shape. It’s available in many customised variations (customised color, number of teeth, customised laser engraving). The surface comes with anodized or nickel-chrome finishing. Anodizing can be made with 12 colors and some of them in 2-3 different color tones. The nickel-chrome surface enhances lifespan and has an extra production cost (12% of the price).
