Description NEUTRON MK2 CASSETTE PRECISION SHIFTING AND DRIVETRAIN REFINEMENT The Neutron cassette is engineered to deliver precise and dependable gear changes across its 12-speed range. Through precision CNC-milled tooth profiles and optimized shifting ramps, each transition between cogs is deliberate and smooth, reducing hesitation under load and promoting confident cadence control. Whether paired with Shimano or SRAM drivetrains, the design emphasises refined engagement and quieter operation compared to typical stock cassettes, enhancing overall drivetrain responsiveness without unnecessary complication. LIGHTWEIGHT OPTIMISED 11-30T: 180g11-34T: 185g A standout characteristic of this cassette is its emphasis on low mass. Even in the larger 11-34T configuration, the Neutron cassette maintains a featherlight presence that sits well below many conventional options — contributing to a perceptible reduction in rotational weight. This weight performance helps maintain the bike’s overall agility and acceleration feel, which is especially noticeable during sustained climbs and dynamic efforts. DLC AND PVD COATINGS Surface treatment is a core differentiator in this cassette’s design. The optional Diamond-Like Carbon (DLC) coating offers an exceptionally low friction interface, facilitating slicker gear changes and reducing drivetrain drag, while the enhanced PVD process prioritises wear resistance for riders focused on durability and long service intervals. Both finishes extend component life beyond standard treatments and allow riders to select a balance between responsive shifting characteristics and long-term reliability based on their usage priorities.

COMPATIBILITY CategoryDetailsFreehub BodyShimano HG Road 11/12-speedSupported DrivetrainsShimano® 12-speed systemsSRAM® 12-speed systemsSRAM AXS NoteFor optimal performance with SRAM AXS systems, we recommend using a Shimano 12-speed chain. Note: Always confirm derailleur capacity and chain compatibility before installation. DURABILITY To ensure a flawless transition and to guarantee the quiet, precise shifting the Neutron Cassette is designed for, we strongly recommend installing a new chain at the same time. Pairing a new cassette with a worn chain is the primary cause of drivetrain noise and can lead to premature wear of both components. IN THE BOX 1x Neutron Cassette MK21x Alloy Lockring
