The Many Benefits of Titanium

Alongside the smooth ride, beauty, and lightness of titanium, the Octane Sub4's frame material is out of this world. Strong as steel but 45% lighter, titanium has the highest strength-to-weight ratio out of all the known metals. The Octane Sub4 is a breeze to push, wherever you go. It’s built to be durable, so you have peace of mind knowing you can take it anywhere.

  • The Octane Sub4's titanium frame has natural built-in shock absorption to soak up road vibrations, which means that it delivers a super-smooth and comfortable ride quality like none other.

  • Titanium will not rust and is very resistant to corrosion & salt water. It's perfect for adventures out and about.

  • As strong as steel but 45% lighter, titanium has the highest strength-to-weight ratio of all known metals and is often used in aerospace applications.

  • A titanium frame like the Octane Sub4's has a far greater ability to bend without breaking, elongating by up to 25% compared to around 15% for steel and 8% for aluminum.

The Many Benefits of Titanium

Why Choose Made-to-Measure?

    Over 30 individual measurements down to a 5mm (0.25") tolerance are taken, allowing a chair to be crafted that fits the rider like a prosthetic.
    One of the ways to achieve the lightest wheelchair possible is to build that chair exactly to the rider's specifications. That means no excess material, adjustments, or dimensions.
    A wide range of ergonomic options such as seats and backrests are available to provide optimum posture, balance, and comfort.
    An RGK expert on made-to-measure manual wheelchairs, the RGK Genius will work with the rider, clinician, and provider to create the perfectly fitted chair.

"My made-to-measure sport and daily wheelchairs fit me perfectly. They're lightweight, comfortable, and easy to maneuver. I couldn't ask for anything better." – Abdi Jama, Wheelchair Basketball Paralympian
