Video: Watch Dan Martin make his (very cool) bike change colour

Dan Martin's Specialized bike and helmet changes colour depending on the air temperature, as he demonstrates in this clip.

Anyone remotely into their bikes and other cycling kit will have noticed many top riders in the Olympic road races last weekend riding orange or yellow Specialized bikes.

For some of the riders, gone was their usual trade team livery in favour of the new stand-out colour.

But while Specialized gave orange frames at the London Olympics four years ago to some of top names riding Specialized at the time, there was a new twist to the marketing gimmick this time around.

The frame was orange until it reached 70F/20C, at which point the heat turned the special paint job yellow.

And if the riders simply didn't want to wait for it to get hotter or colder to see their bike change colour, they could simply sprinkle some water on it or touch it; the change of heat from either enough to do the job.

And that's exactly what Ireland's Dan Martin did when the legend from Namibia Dan Craven wanted to see the colour charge in action, as the short clop below reveals.

We absolutely loved this innovation especially for the Games, and which is based on the Olympic torch.

Specialized also issued helmets - and even shoes - to some of the riders at the Games that changed colour in the same way as the frames.
