Simucube’s new steering rim

The Tahko GT-21 high-end sim steering wheel is Simucube’s first foray into the sim racing wheel world and makes a bold statement about their intention to become a sim racing ecosystem rather than an individual sim racing component supplier. According to Simucube, months of R&D and a rigorous testing plan has delivered a very high quality and well manufactured wheel that has been pitched by the reviewers as a “wheel that will last a lifetime.

Ideal for the hardened GT racer

This 320mm wheel features an Alcantara finish, 12 momentary push buttons, a 7 way funky switch, a rotary encoder, Simucube Wireless wheel technology and Simucube’s excellent SQR quick release (wheel side) fitting. Weighing in at 2.1kg this wheel has a weight very much comparable to the Cube Controls GT wheels. It feels very solid and flex free in your hands and very clearly, Simucube have used high quality manufacturing processes and componentry to create this wheel.

Cutting edge look and feel

The Tahko features a CNC machined chassis with black anodising on the front and orange anodizing on the rear. A Simucube logo “triangle” is bolted on the front. The unit itself is an aggressive and unique design that will appeal to the sim racer who wants their gear to look a little different from the rest.

“No flex” built in

Around the back of the wheel, the shifter paddles are designed very simply and look well thought out. The “breakaway force” (the amount of force required to get the paddle to activate) feels about right from a driver’s perspective and as you would expect, very precise. There’s no flex or lateral play in the paddles – they feel stiff, well-built and professionally designed.

Introducing the Simucube button

Make small adjustments to the feel of your FFB (force feedback) while you’re in session using the new Simucube button on the rear. The Simucube button allows you to adjust FFB strength, Damping and the Simucube filter without directly accessing TrueDrive – a feature not unlike the Fanatec tuning button found on their wheels. This is “a unifying feature” from Simucube that we expect to see in all future Simucube device releases.

Wireless Wheel Technology and SQR hub pre-fitted

The Simucube Wireless Wheel Technology battery life is estimated at about 5 years but just in case you need to change the battery cell, it’s accessed via a panel on the rear of the wheel chassis.

The Tahko comes fitted with the wheel side SQR hub – meaning that the wheel is literally “plug and play”. As an ecosystem this makes the Simucube universe just as accessible to new drivers as the Fanatec world; a definite upside is not having to fit a QR hub to the wheel before you get started!

What’s included?

  • Simucube Tahko GT-21 Steering Wheel
  • Official Quick Start Guide
  • Sticker set for the wheel
  • Standard Lithium battery included
  • SQR hub included

Installation and drivers

If you own the Simucube SQR hub on your Simucube 2 Sport, Pro or Ultimate, then installation is as simple as putting the ready-assembled wheel on the wheelbase, pairing the Wireless device in Truedrive and re-centering the wheel.

The Tahko GT-21 is designed to take the hassle out of matching a wheel and hub to your Simucube; by being “plug and play” much like Fanatec has been for many years. If you want to mount your Tahko via a different QR hub you will need a 6x70mm PCD wheel hub adapter to mount on the rear of the wheel chassis, upon which you can mount the QR system of your choice.

Useful links, drivers, and manuals

    Simucube Tahko GT-21 Wireless

    I haven’t spent too much time with this rim as I bought it simply to have a round rim to partner the Ascher F28, however I will give you my first impressions.

    The wheel is solidly built as you expect, the buttons and rotaries feel good and positive to use. There’s really nothing at all to complain about. The “Simucube” button is interesting as it allows you to alter certain profile parameters on the fly such the FFB amount, but I haven’t used it as I’m a FFB set and forget kind of guy, and never feel the need to alter the FFB while I’m driving. However I’m sure this will be a major selling point for some.

    The alcantara type material used to cover the rim feels a little rough to me, but after reading around it appears that this was a deliberate design choice by Granite Devices to increase the longevity of the material, and in any case you should be wearing gloves with alcantara rims as they get very manky pretty quickly if you don’t.

    The wireless connectivity has been perfect during my use with no dropouts and all controls and buttons registering without issue. No complaints there.

    The colour scheme is a bit meh, but I’m not complaining as I bought the wheel to drive with, not to admire.

    If you need a GT style round rim to accompany your open wheel rims then this would make a fine choice in my opinion, especially if you see yourself making use of the “Simucube” button to make on the fly adjustments to the FFB.
