Black Inc Sixty Clincher Disc Wheelset

Black Inc is not a large company — they produce a limited range of products, build them carefully, and let the results speak. The Black Inc Sixty Clincher Disc Wheelset is the deepest road-focused wheel in their lineup: 56mm of UD carbon depth, 1,575 grams, and a design refined in CFD software then validated by sponsored pro teams racing on actual roads. The Sixty targets road racing and middle distance triathlon — a depth that offers meaningful aero return without the handling compromise that comes from a full 80mm profile. Black Inc's sponsored racers were already racing the Fifty series and asked for more speed. The Sixty is the result.

CFD-Shaped Rim and Wide Profile

The Sixty's rim was formulated through CFD analysis and then tested at the WorldTour level before reaching consumers. The numbers — 56mm deep, 30mm external width, 21mm internal width — were chosen together rather than optimized in isolation. The wide external profile gives the wheel its crosswind stability: rather than catching air, the flared shape manages it, which is what separates a genuinely usable 56mm wheel from one that becomes a liability on exposed roads. Internally, the 21mm channel properly supports 25-30mm tires — the range that road riders have increasingly moved toward as tubeless at moderate pressure has proven faster and more secure than narrow tires at high pressure. The UD carbon tubeless-clincher channel design carries over from Black Inc's Thirty and Fifty series, a profile they've been refining over several years of real-world use. When run tubeless with a 25-28mm tire at moderate pressure, the tire conforms to the road surface rather than skipping over it — rolling resistance and traction improve together. Tubeless tape, valves, and 70mm valve extenders are included.

CeramicSpeed Bearings and Sapim CX-Sprint Spokes

The disc-specific hubs are machined from aluminum with an optimized flange geometry designed to balance wheel stiffness and rider comfort through the straight-pull spoke arrangement. Oversized alloy axles run on custom-specified CeramicSpeed bearings — installed in both the hub shells and the freehub body, not just one or the other. CeramicSpeed reduces bearing friction compared to standard steel and outlasts them with routine maintenance. The freehub uses an interchangeable design: the body swaps between Shimano HG11 and SRAM XDR configurations without replacing the hub, a practical feature if you change drivetrains at any point. Twenty-four Sapim CX-Sprint straight-pull bladed spokes are laced 2x/2x front and rear with hidden nipples. CX-Sprint is a known quantity in high-performance wheel building — resilient at the high tension these rims require, lightly bladed to reduce aerodynamic drag, and light enough not to add unnecessary rotating weight. The front accepts 12x100mm and the rear 12x142mm thru-axle; 15mm front endcaps are included. Disc interface is Center Lock, and lockrings ship with the wheelset.

A Race Wheel for Real Conditions

The 56mm depth hits the range where aero gains become significant without crosswind sensitivity becoming a problem on exposed roads or in variable weather. The Sixty's wide rim profile contributes to this: at 30mm external width, the wheel manages air rather than catching it, and the combination of depth and width is what makes this a usable race wheelset rather than a fair-weather-only choice. At 1,575 grams (bare wheelset), it lands at a weight consistent with its construction quality — not the lightest 56mm carbon disc wheelset available, but built to a standard sufficient for UCI approval and handcrafted with the care that comes from a brand that does not rely on volume production. These are artisanal wheels, built to order, with the same bearing and spoke specification Black Inc has been equipping professional teams with.

What's Included

The Sixty ships with tubeless tape and valves, 70mm valve extenders, and 15mm thru-axle front endcaps — everything needed to build up and run tubeless immediately. The finish is UD carbon with subtle gray graphics: understated enough to work across frame colors, consistent with Black Inc's minimal aesthetic. Minimum recommended tire size is 700x25c. For a road rider who has committed to 25-28mm tubeless and wants a 56mm disc wheelset with CeramicSpeed bearings, Sapim spokes, and the manufacturing credibility of a brand that equips WorldTour teams — the Sixty is a complete, coherent package at $2,399.
