RGK Octane
Sub4 Titanium

Transferring, propelling, lifting, turning… All effortless with 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, weighing in at only 4kg.

The titanium absorbs shocks and soaks up road vibration, delivering a super-smooth and comfortable ride.

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.
