Product Description

RGK Octane Sub 4 Titanium Wheelchair

The Octane Sub4 frame has natural in-built shock absorption to soak up road vibration, which means that it will deliver a super-smooth and comfortable ride quality like no other. The titanium frame has a far greater ability to bend without breaking, elongating by up to 25% compared to around 15% for steel and 8% for aluminum.

Alongside the smooth ride, beauty, and lightness, the Octane Sub4’s 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. 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.
