Overview

What makes the Black Inc 48|58 Wheelset steady in crosswinds?

The Black Inc 48|58 Wheelset pairs a 48mm deep front rim with a 58mm deep rear rim, a split Black Inc chose to keep the bike stable in high wind at all yaw angles while still delivering deep-section aero speed. Black Inc developed the set to match the aerodynamics of the Factor OSTRO VAM, and the shallower front rim is what keeps the steering calm when a gust hits. The mini-bead hook rim has a 23mm internal width optimized for 28mm tires, and it runs tubeless tires or clinchers with inner tubes, so your tire choice stays wide open.

The rims are laced 2-cross with Black Inc straight-pull aero carbon spokes to high-flange HU-08 alloy hubs that spin on Black Inc + CeramicSpeed bearings, with Center Lock rotor mounts and 12mm thru axles. Black Inc lists the set at 1300g with a Shimano driver, and every wheel is hand built and inspected on electronic machines. We stock the 48|58 in Silver with a SRAM XDR driver, and the Black finish and Shimano HG driver are available to order. It suits road riders on a fast aero bike who want deep-section speed without a nervous front end.

Why is the Black Inc 48|58 front rim shallower than the rear?

Black Inc uses a 48mm front rim and a 58mm rear rim so the front wheel, which steers the bike, catches less crosswind, while the deeper rear rim adds aero speed.

Can I run inner tubes on the Black Inc 48|58?

Yes. Black Inc lists the 48|58 for tubeless, tubeless ready and clincher tires with inner tubes, and the rim is optimized for 28mm tires.

Which freehub should I choose for the Black Inc 48|58?

Choose SRAM XDR for SRAM 12-speed road cassettes. Choose Shimano HG for Shimano HG 10/11-speed or SRAM 10/11-speed cassettes.

Does the Black Inc 48|58 only fit Factor bikes?

No. It was developed alongside the Factor OSTRO VAM, but it uses 12mm thru axles (100mm front, 142mm rear) and Center Lock rotors, so it fits disc road bikes built to those standards.
