RGK Octane Sub4 Lightest Titanium Rigid Active Wheelchair

Sunrise MedicalSKU: 35-2/OCTANESUB4



RGK Octane Sub4 titanium Grade 9
The titanium revival is upon us – and it is exceptionally light

4kg*. That’s a newborn baby. A 7 week old Labrador puppy. Your Octane Sub4. The classic Octane design has been redefined, combining it with tried and tested Sub4 technology and a hand crafted made to measure titanium grade 9 frame.
Titanium has this wonderful natural quality that absorbs shocks and soaks up road vibration, delivering a super-smooth and comfortable ride quality for you. Transferring, propelling, lifting, turning… All effortless with your Octane Sub4.

“Christmas has certainly come early. This is more of a work of art than a chair. It’s definitely the most beautiful chair I’ve ever owned. There’s a noticeable difference in weight even compared to my MaxLite – just having it as light as it is will make a huge difference; it will certainly save my shoulders over the years to come.
I think it’s important to have a good looking chair: a well-fitted chair is important in giving me confidence too. Even though I’ve only had it a day, a few people have already said that even though it’s thicker tubing than my previous chair, it is actually less noticeable!” - Tim Farr

“It's half the weight! As it's faster you actually feel more secure, getting up and down kerbs, it's just planted so well. It feels good to be in the chair... And I think it looks cool as well!" - Chris Toon

No corrosion
Titanium will not rust and is very resistant to corrosion and salt water.
Perfect for adventures out and about.

Smooth riding
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.

A 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 aluminium.

Strength to weight ratio
Strong as steel but 45% lighter, titanium has the highest strength-to-weight ratio out of all the known metals.

Style, performance and still under 4 Kg*
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.
