Close up: Pure Racing

Pure Bikes are a new British brand creating top of the line race frames designed to help racers get the most out of their strength as well as having thoroughly tested geometry.

Here’s how they do it…

You may have seen riders such as Dan McBride, Ryan Stack and Ethan Vernon riding these frames at races, but there are a couple of small touches that make them standout.

The alu frame has some unique features developed as a result of in-depth analysis to determine where power loss and flex which may occur. These design features are explained below:

1. The specially formed top tube incorporates an internal rib stiffener and is horizontally ovalised to strengthen the contact area at the head tube and seat post. This will reduces the out of plane bending caused by forces from the handlebar region.

2. The oversized down tube is specifically designed to withstand forces induced from front end impacts and is horizontally ovalised at the bottom bracket to reduce the out of plane bending caused by pedalling.

At Pure Bicycles, we only use tubes from the best aluminium alloys available. Top quality performance is achieved with the use of SC610 A-T6 and 7003_T6 alloys; whose breaking point comfortably reaches 470N/mm2. These alloys possess a surface hardness of 135HV after ageing and heat treatment. Heat treatments act on these high Cu-Zn-Mncontent aluminium alloys to guarantee high mechanical properties and superior resistance to the cyclical stresses a race frame is subjected too.

Our frames are subject to a series of exhaustive tests to ensure our customers can be assured they are purchasing a quality product.
