When you want to keep pace both on climbs and on the flats, the details in your drivetrain matter. Shimano Ultegra CS-R8101-12 delivers smooth shifting that won’t break your rhythm.
HYPERGLIDE+ technology supports fast, fluid shifts up and down, even under high pedaling force. It helps you maintain a steady cadence at race pace.
A cassette with a 11–30 tooth range gives you a sensible reserve for climbs without sacrificing the tight gearing steps for brisk riding on the flats.
Twelve speeds make it easier to choose the right gear between pushing hard and keeping your legs fresh. In practice, that means fewer compromises when the pace changes.
Steel sprockets and an aluminum sprocket carrier provide strength while saving weight. It’s a great fit for a road bike as well as gravel when you want reliable power transfer.
Cassette technical designation: CS-R8101-12 for a 12-speed drivetrain.
Cassette gearing: 11-12-13-14-15-16-17-19-21-24-27-30 teeth.
Cassette weight is 0.291 kilograms for the 11–30 tooth version.
Freehub type is Shimano HG L2 for a compatible hub.
Shimano Ultegra CS-R8101-12 is a road cassette built around precise shifting and efficient power transfer. It’s suitable for sporty road riding as well as gravel, where gradients and pace often change.
With the well-chosen 11–30 tooth gearing, you get gears for fast sections and controlled climbs. For a matched drivetrain setup, it’s designed to be used with the Shimano CN-M8100 HG 12-speed chain.
The “Nebaleno” version means it comes without retail packaging; the cassette itself remains a full-featured drivetrain component. It’s a practical choice when you’re servicing or building a bike.
