Yes, it is an all-in-one solution. The kit includes the pre-bled hydraulic brake, the hub, the rim, and the Stacked Hydro power brake adapter, so you won't need to source additional mounting hardware or bleed the lines yourself.

This system uses mineral oil. Do not use DOT fluid, as it will damage the seals and internal components of the hydraulic system.

The kit is designed specifically for a 160mm rotor. Please check the product listing details to confirm if your specific bundle includes the rotor, as some configurations may require you to source the disc separately.
