What it is
The Simucube Tahko GT-21 is Simucube’s first in-house GT wheel. 320mm D-shaped, CNC billet aluminium throughout. Nearly every contact surface is machined metal, with plastic limited to button faces and two wireless module covers. 10 push buttons, 1 five-way funky switch, 1 rotary encoder, magnetic shifters with neodymium magnets, and rubber bump stops for quiet operation. Suede grips. Native Simucube wireless via a CR2477N button cell that lasts 2+ years.
At $859, it sits in the high tier. It ships with a Simucube SQR wheelside adapter (zero flex) and uses the standard 70mm bolt pattern, so the rim is swappable.
Who it’s for
Simucube wheelbase owners who want a first-party GT wheel with native wireless and zero configuration. If you run a Simucube 2 Sport, Pro, or Ultimate and want a wheel that pairs instantly without adapters, cables, or firmware headaches, the Tahko delivers that with all-aluminium build quality.
The dedicated Simucube button for on-the-fly FFB tuning (overall strength, dampening, force reconstruction filter) is a genuine workflow improvement. No alt-tabbing to True Drive mid-session.
In use
The aluminium construction defines the experience. Every surface feels cold, dense, and precisely machined. It has the tactile quality of a real race car wheel rather than a consumer peripheral. The magnetic shifters are excellent: positive feel, quiet action (rubber bump stops), adjustable width. Push buttons have a clean positive click with no hollow reverberation.
The SQR quick release is rock-solid. Zero perceptible flex or play. Combined with the wireless connection, the Tahko feels completely untethered from the rig in a way that cabled wheels cannot match.
The Simucube button works well for adjusting FFB profiles between cars without leaving the sim. The adjustment is functional, though it lacks a visual overlay, so you are making changes blind.
Suede grips are rougher than the softer alternatives on competing wheels. Simucube chose durability over initial comfort. With gloves, the texture is excellent. With bare hands, it takes a few sessions to stop noticing.
What to watch out for
The input count is conservative for the price. 10 buttons, 1 funky switch, and 1 rotary encoder is noticeably less than the Cube Controls GT Pro V2 or other wheels in this price range. No thumb encoders, no toggles, no backlit buttons, no display.
The D-shape makes this unsuitable for drifting or rally. You cannot let it slip through your hands.
The Simucube ecosystem lock-in is total. Wireless only works with Simucube bases. If you move to a different wheelbase brand, this wheel loses its defining feature.
The orange colour scheme is the only option. If that clashes with your rig aesthetic, there is no alternative colourway.
Verdict
A premium GT wheel that does less than competitors but does it with better materials and build quality than almost anything in the category. The all-aluminium construction, quiet magnetic shifters, and native Simucube wireless create a cohesive, premium experience. The limited input count is a deliberate trade-off for simplicity and build quality. If you value feel and materials over feature density, and you are in the Simucube ecosystem, the Tahko earns its price.
