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.
Smooth Ride
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.
No Corrosion
Titanium will not rust and is very resistant to corrosion & salt water. It’s perfect for adventures out and about.
Strength-to-Weight Ratio
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.
Durability
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.
