Raketa Supersport Сhainring

Please note that the remaining Supersport chainrings are available only in Black!

We originally developed this chainring for world-class competition, with a special focus on the 2020 Tokyo Olympics.

After months of development and testing by world champions, the Raketa Supersport chainring is now available to the public.

Raketa Supersport Chainring was used to set an impressive World Record:
— Women’s Flying 200 m — 9.976 s (set by Yuan Liying, 15.03.2025) — the first woman ever under 10 seconds.

The Raketa Supersport chainring was engineered using FEM analysis to achieve the optimal stiffness-to-weight ratio. The backside features a honeycomb structure, individually calculated for each size, to maximize stiffness while minimizing weight. The front side is aerodynamically optimized for racing conditions.

As a result, this is the stiffest chainring on the market, and likely the lightest large-sized alloy chainring as well. On average, it is 10% stiffer than the Sugino Zen. The Supersport chainring easily withstands power outputs of over 2500 watts, as produced by the world’s top male sprinters.

At the same time, thanks to advanced machining, even the 60T version weighs under 200 grams.

The tooth profile was developed from our experience in producing Raketa Pro track cogs. The mirror-polished teeth of the Supersport chainring minimize friction, ensuring unmatched drivetrain smoothness. Pair it with a Raketa Pro cog for performance as seamless as a submarine’s operation.

The Raketa Supersport chainring is manufactured from 7075-T6 aluminum — the strongest alloy of its kind.
Available in sizes from 47T to 63T, in all Raketa anodized colors.
Compatible exclusively with 1/8" chains and 144 mm BCD cranksets.

Please always ensure that oversized chainrings are compatible with your frame’s clearance.
