Designed and tested for/by track racers! Best choice for trick fixies, bike polo and for everyday road trainingor commuting. The Sprinter design is compatible with Shimano 7710, Miche Primato, Sugino 75 track crank arm and all 144 BCD crank arms. (some cheap taiwanese Cranks might taight fit ) Both sides of the chainrings are smooth polished and come with anodized or nickel-chrome finishing. They have smoother and rounder tooth valleys and smoother tooth tops that reduces chain noise and results better runnning chains. The thickness of the drop design shape is only 1.2 mm! When reeling harder shearing stress grows on the teeth and on the boltholes of the chainring. The unique design of the drop shape is based on how the stress travels on the ring, so that’s why it’s possible to reduce the thickness on those parts. This makes Yobi Sprinter’354 one of the best track chainrings on the market. For availability of colors and sizes contact me via mail.
