Black Inc Wheels - RA Cycles

Ruedas Black Inc.

Black Inc makes one tier of wheel — the best one. Their in-house team of engineers uses Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and Rapid Prototyping to develop every model, and every hub ships with CeramicSpeed ceramic bearings as standard — not as an upgrade option. Black Inc designs its hubs from the ground up to match CeramicSpeed’s handmade bearing tolerances, which is a fundamentally different approach from brands that simply swap in ceramic bearings after the fact.

The RA Cycles collection covers the full Black Inc range: from the climbing-focused Twenty and the versatile 28|33 through to the aerodynamic Forty Five and the deep-section Five — plus rim brake and track options. Every model is proven at WorldTour level through Black Inc’s partnership with Israel-Premier Tech.

About Black Inc

Black Inc’s philosophy starts with an engineering constraint they imposed on themselves: one product tier, and it has to be the best. Their in-house designers and engineers use FEA (Finite Element Analysis), CFD (Computational Fluid Dynamics), and Rapid Prototyping, and every Black Inc wheel rolls on CeramicSpeed ceramic bearings — built into the hub design from the outset, not retrofitted. The brand owns its manufacturing facilities, runs its own in-house test lab, and validates everything through real-world racing with Israel-Premier Tech at the WorldTour level. More at blackinc.cc.

The RA Cycles Black Inc selection covers 16 wheels across disc and rim brake formats at multiple rim depths. The Twenty is the lightweight climbing option; the 28|33 pairs a 28mm front with a 33mm rear for optimized handling across variable terrain; the Forty Five and Five step up in depth for flat roads and time trial efforts; and the Sixty Track is the tubular track-specific option. Black Label variants of the Twenty are available for riders who want the full premium specification.

Browse the complete wheel selection at RA Cycles, or explore other premium options including Lightweight wheels and Zipp wheels.

R&A Cycles - 50th Anniversary

50 YEARS AND COUNTING

From a Brooklyn storefront to flagships in Walnut Creek and Miami, from handwritten mail orders to a fully digital custom bike builder — RA Cycles has spent half a century doing one thing: serving riders who demand the best. That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here. Here's to the next fifty.
