The essential Titanium alloy Cycle Stak.

Lightweight, tough, high performance tools for the rigours of the road or trail. All parts are machined from aerospace grade Titanium alloy. These are then plasma nitride hardened for durability.

Non corrosive, Scratch resistant, superlight and tough.

Stak includes:

Hex keys // 2mm, 3mm, 4mm, 5mm and 6mm. Plasma hardened Ti6Al4V

CS01 Chain Splitter// Tough and light. Plasma hardened Ti6Al4VAn

Extreme conditions require extreme materials

We use titanium alloy for a reason. It’s high Tensile strength to density ratio. In layman’s terms it’s strong and light. In fact it’s half the weight of standard steel. This makes it the perfect material choice for anything where weight is important. Titanium alloy was originally developed for the aerospace industry to allow planes and spacecraft to fly faster, higher and further. We have chosen to apply it to the world of outdoor adventure sports for the same basic reasons. When you are on your bike or in the mountains you feel every gram that you carry. Windeler tools are designed to be unnoticeable on your adventure until the moment you need them allowing you to go further, higher and faster.

A mysterious discovery that changed the world

In 1791 Cornishman William Gregor began a detailed chemical analysis on the Lizard Peninsula in Cornwall. He unearthed a metal ore previously unknown to science with strange properties.

Titanium – Named after the Titans of Greek mythology because of it’s other-worldly properties. It’s lightweight, tough, non toxic, non magnetic and non corrosive. Half the density of steel but with high tensile strength which makes it perfect for anything where weight and strength are important.  This made it a prized material for the aerospace industry in the early and mid 20th Century where it was developed and first alloyed.
