New products for the cyclist
Manufacturers need to keep up to speed, says Peter Marsh
As a keen cyclist, Yoshizo Shimano knows all about the importance of keeping in touch with his company’s products. (3) Mr Shimano is president of Shimano, the world’s biggest maker of bicycle components. Frequently, he borrows a bike from the company’s R&D division to keep (6) in touch with what researchers are up to.
‘We won’t compete with our customers by building complete bikes. But we must keep in mind (8) how our components are going to be used and have a vision of the product that is safe as well as being fun,’ he says.
Mr Shimano’s interest in trying (11) out bicycles containing his company’s components underlines how manufacturers must pay increasing attention to bringing out new products. These (13) must either solve a pressing customer problem or come up with an idea that breaks completely new ground within a few years.
(16) ‘For example, if the cyclist does not have to change gears, he can concentrate on other aspects of controlling the bike which is likely to lead to safer journeys,’ (18) says Mr Shimano.
