The SRAM Kolben RED 22/700 HRD is a high-performance hydraulic disc brake component designed for riders who demand precise, consistent braking on the road. Part of SRAM’s premium RED series, this piston unit is engineered to deliver smooth modulation and powerful stopping force, even under sustained braking or in changing weather conditions. It is intended for use with SRAM’s HRD (Hydraulic Road Disc) systems, making it an ideal choice for performance road bikes, endurance machines, and fast gravel or all-road setups that rely on reliable hydraulic braking.
Built around SRAM’s proven hydraulic technology, the Kolben RED 22/700 HRD focuses on efficient power transfer from lever to caliper, helping to reduce hand fatigue on long descents and during intense rides. Its design supports consistent pad movement and even pressure distribution, which contributes to quieter operation and more predictable braking feel. This component is well-suited for riders upgrading or servicing their existing RED HRD brakes, ensuring compatibility with modern disc brake standards and high-end drivetrains. Whether you are racing, training, or tackling challenging terrain, it helps maintain the crisp, confident braking performance that SRAM RED is known for.
