The Ascher Racing B24-SC isn't trying to please everyone, and it stands by that. This is a wireless control panel designed for a very specific ecosystem—that of Simucube Direct Drive bases—intended for drivers who want to transform a simple round rim into a full-fledged GT steering wheel without a single cable in the way. The stated goal is eSports-level reliability and precision on the track—not flashy gimmicks.

A machined aluminum block

It all starts with the chassis. The body of the B24-SC is milled from automotive-grade aluminum, black anodized, and then laser-engraved, with a brushed front panel and micro-beaded paddle surfaces. Weighing 700 grams for the plate alone, it’s a solid piece that won’t bend or twist. That’s exactly what you’d expect from a control mount designed to withstand high torques on a high-end platform, without the slightest flex interfering with your grip. The finish and assembly immediately position the B24-SC in the premium segment of sim racing accessories.

Twenty-four orders in the works

Ascher announces a total of twenty-four inputs, logically arranged. There are eight push buttons with crisp, tactile feedback, two additional push buttons protected by covers (ideal for functions that shouldn’t be triggered by mistake, such as the pit limiter), and, most notably, two seven-way aluminum joysticks. These joysticks combine four directions, clockwise and counterclockwise rotation, and a central push button, which expands the range of accessible functions without ever having to release the joystick’s grip. To properly map iRacing, Assetto Corsa Competizione, or Le Mans Ultimate, the kit includes about a hundred button labels and several dozen joystick labels.

Adjustable magnetic paddles

The paddle shifters are one of the most meticulously designed features of this dashboard. The full-height, GT-style levers are machined from aluminum and operate on a magnetic principle, eliminating metal-to-metal contact and unwanted noise. The real advantage is its modularity: Ascher includes replacement magnets and spacers that allow you to adjust the actuation force, from a light shift of around 260 grams to a very firm shift of nearly 800 grams. This allows each rider to adjust the paddle click to their preference—a level of detail that remains rare on the market.

Wireless Technology by Simucube

The B24-SC is an officially licensed Simucube Wireless Wheel. Specifically, control signals are transmitted directly between the plate and the base—without a dongle or coiled cable—with response times in the order of milliseconds. Power is supplied by a single 14250 lithium battery, accessible through a compartment on the back, which is rated for two to three years of battery life even with heavy use. An external antenna ensures signal quality. Another practical benefit: you can swap out the rims on the fly without having to reconfigure the inputs each time.

Compatibility: The Simucube Ecosystem on PC

We need to be clear about the scope. The B24-SC is designed for Simucube 2 bases (Sport, Pro, and Ultimate); the Simucube 1 requires an additional receiver module. This means it’s exclusively for PC use, with no PlayStation or Xbox compatibility: it’s not a console steering wheel, but a component for a high-end Direct Drive setup. It mounts using a 70 mm six-hole pattern, compatible with Simucube’s Quick Release V2 (not included), and the mounting plate accommodates many round steering wheels available on the market (MOMO, OMP, Sparco, Sportline, among others). The M and L variants are specifically designed to fit the shape and size of the chosen rim.

Who It's For

The B24-SC is aimed at a specific audience: sim racers who already own a Simucube base unit and want to build a custom, rugged GT steering wheel free of wiring. We appreciate the overall cohesiveness of the design, the quality of the machining, and the wide range of controls. On the other hand, the closed ecosystem and the fact that neither the rim nor the Quick Release are included clearly limit this product to advanced setups. For this audience, it’s a functional work of art that checks all the right boxes.
