Black Inc 48|58: The Perfect Companion for the Factor Lineup

Black Inc is the component brand under Factor Bikes, specializing in high-end accessories such as carbon wheels, handlebars, and seatposts. The 48|58 is Black Inc’s aero flagship wheelset, featuring an asymmetric rim depth design of 48mm front / 58mm rear, with system-level aero optimization tailored for frames such as the Factor O2 VAM and Ostro VAM.

Product Specifications

Part of the Factor Ecosystem

Black Inc shares R&D resources and design philosophy with Factor Bikes. The 48|58 wheelset was developed in close collaboration with Factor’s frame team during the development phase, ensuring that the wheelset’s aero characteristics perfectly complement the frames.

The CeramicSpeed Advantage

The standard-equipment CeramicSpeed ceramic bearings are a major highlight of Black Inc. CeramicSpeed is a top-tier Danish bearing brand, and its ceramic bearings offer extremely low rolling friction, measuring 3-5 watts lower than standard steel bearings in testing. This upgrade typically costs an additional NT$10,000-15,000, but it comes as standard equipment on the Black Inc.

DT Swiss Ratchet EXP Internal Mechanism

Similar to Bontrager, Black Inc also chose to use the DT Swiss Ratchet EXP internal mechanism within its own hub shells. This strategy balances brand identity with mechanical reliability.

The Design Logic Behind 48 Front / 58 Rear

Asymmetric front-rear rim depths are one of the trends in high-end carbon wheels. Black Inc chose the 48mm front / 58mm rear combination for the following reasons:

• 48mm front: Strikes a balance between crosswind stability and aero efficiency
• 58mm rear: Sheltered by the rider’s body, the deeper rim provides greater aero gains
• 10mm difference: More aggressive than ENVE (4mm difference) and Roval (9mm difference)

Real-World Riding Experience

The CeramicSpeed Feel

The CeramicSpeed bearings are most noticeable during high-speed cruising. The hub rotation is exceptionally smooth, and the deceleration rate when coasting is noticeably lower than with standard steel bearing hubs. This difference accumulates into something substantial over long-distance rides.

The Balance of Aero and Lightweight

The 48 front / 58 rear rim depth combination, paired with a 1,380g weight, allows the 48|58 to perform excellently on both flat roads and rolling terrain. The 48mm front wheel ensures good handling, while the 58mm rear wheel provides additional aero propulsion during cruising.

Pairing with Factor Frames

If you ride a Factor O2 VAM or Ostro VAM, pairing it with the Black Inc 48|58 creates a sense of harmony that feels “made for each other.” The lines between frame and wheelset transition fluidly, and the overall aero consistency of the complete bike reaches a very high standard both visually and in terms of performance.

The Flexibility of Hooked Rims

The hooked rim design means you’re not restricted to specific Tubeless tires. Want to run GP 5000 with inner tubes? No problem. Want to switch to Tubeless? Totally doable. This flexibility is valuable for riders who frequently change their tire setups.
