Shimano Ultegra R8000 Cassette

Yes, this cassette is designed specifically for 11-speed road drivetrains. It is compatible with most Shimano 11-speed road derailleurs, though you should verify your rear derailleur's cage length if you are switching to a wider gear range, such as the 11-32T.

Your choice depends on your local terrain and riding style. The 11-28T offers tighter gear steps for flatter roads and maintaining a consistent cadence, while the 11-30T and 11-32T provide easier climbing gears for steep gradients or hilly routes.

Absolutely. The Ultegra R8000 is a popular choice for gravel setups because of its durability and precise shifting under load. Just ensure your rear derailleur has the capacity to handle the specific tooth range you select.

The R8000 cassette fits standard Shimano/SRAM 11-speed road freehub bodies. If you are using a 10-speed wheel, you may need a spacer, and it is not compatible with SRAM XDR drivers without a specific adapter.

The R8000 sits in the middle of the range, offering a balance of weight and durability that is often considered the 'sweet spot' for performance. It is lighter than the 105 series but more budget-friendly than the top-tier Dura-Ace, which utilizes more exotic materials to shave off extra grams.
