"Cycling touches the lives of everyone in the world at some time: from little children in cities and rural areas who learn to ride at a young age, to teenagers and adults who rely on a bicycle to get to school or work and back.
"At the same time, technology unites people, and enables organisations to do things better, faster, and more cost-effectively." Dimension Data group chief executive, Brett Dawson, said optimising the experience of fans, and providing them with a richer, more intimate experience of cycling was at the heart of the company's goal.
