SunRace CS-R86 Cassette — 8-Speed, 11–28T (Nickel)

The SunRace CS-R86 cassette is a lightweight, smooth-shifting 8-speed cassette designed for road, fitness, and commuter bikes that prioritize efficient cadence steps and reliable performance.

Built with SunRace Super Fluid Drive™ technology, the CS-R86 delivers clean, consistent shifts with reduced noise and improved chain engagement. Compared to more rugged MTB-oriented cassettes, the R86 focuses on tighter gear spacing and lower overall weight—making it well suited for road and endurance riding.

Featuring steel cogs and a steel lockring, this cassette balances durability with a lighter overall package at approximately 250g. It installs on standard Shimano HG-compatible freehub bodies and serves as a direct functional equivalent to several popular Shimano 8-speed road cassettes.
