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).

Yobi chainring family usually supports 1/2″ X 1/8″ chain size:
Sprinter’354            144 BCD               45 – 64 T


1/2″ x 11/128″  for 9 speed chain  (usable with 3/32″chain to, but not ideal)
Steamroller’354       130 BCD               44/45/46/47/48
Oval’354                  130/144 BCD      46/48
