Black Inc Five Clincher Disc Wheelset

The Black Inc Five Clincher Disc Wheelset occupies a rare position in the road wheel market — aerodynamic enough to reward you on flat terrain, light enough to follow you over a climb without protest, and stiff enough to convert every hard effort into forward motion. The five-spoke architecture borrows its visual language from the motorsport world, and while that silhouette turns heads, it's the engineering beneath each curve that justifies the attention.

Black Inc developed the Five around a Kamm tail rim profile, validated through both computational fluid dynamics (CFD) and finite element analysis (FEA) modelling. That dual-method process matters: CFD maps how air behaves around the rim shape, while FEA stress-tests whether that shape will hold under real-world load. The bladed spokes follow the same logic — shaped to reduce drag rather than simply hold the wheel together — and the result is a system where every component is contributing to the aerodynamic goal, not working against it.

The disc-brake platform changes the calculus for deep-section wheels in a meaningful way. Without the heat stress of rim-brake friction on long descents, you can commit to running a deeper, more aero-optimised rim without worrying about what it does to your braking performance on a sustained alpine drop. That makes the Five clincher disc genuinely versatile — as confident in a hard criterium or flat grand fondo as it is navigating the kind of variable, wet-road conditions where rim-brake deep-section wheels have historically demanded compromise.

Design Benefits

1. Kamm Tail Rim Geometry: The truncated Kamm tail profile is designed to manage airflow separation at the trailing edge of the rim, maintaining aerodynamic efficiency across a range of yaw angles. This is the kind of shape that performs on real roads — where wind rarely arrives head-on — rather than only in controlled tunnel conditions.
2. CFD and FEA Co-Development: Most wheels are optimised for one design objective at the expense of another. Black Inc's dual-validation process means the Five's rim shape is both aerodynamically refined and structurally sound, not a compromise between the two. FEA modelling in particular gives confidence that stiffness and load resistance are engineered in, not assumed.
3. Bladed Aerodynamic Spokes: Where a standard round spoke punches through air with minimal regard for drag, the Five's bladed spoke profile is shaped to reduce turbulence and aerodynamic resistance. Fewer spokes, each working harder — both structurally and aerodynamically — is the underlying logic of the five-spoke design.
4. Disc-Brake Platform Versatility: Moving braking force to the hub rather than the rim surface eliminates the heat build-up and braking performance degradation that comes with carbon rim-brake wheels under sustained descending. The Five disc is designed to be ridden hard in mixed conditions, across long mountain stages and wet group rides, without the thermal caveats that come with the rim-brake equivalent.
5. Drivetrain Compatibility: Available in both HG11 (Shimano and SRAM 11-speed) and XDR driver configurations, the Five integrates cleanly with current road groupsets — including SRAM's 12-speed AXS ecosystem via the XDR variant — without requiring additional adapters or workarounds.

Final Take

The Black Inc Five is a disc-brake road wheelset for riders who want a single set of wheels that performs seriously across a wide range of conditions — not a dedicated race-day set that spends most of its time in a bag. It suits the rider who pushes hard on climbs, wants aero returns on flat roads, and has moved past rim brakes for good. Technically considered, visually distinctive, and built around a design process that prioritises validated performance over marketing language.
