The CeramicSpeed oversized pulley wheel (OSPW) system is not a particularly new concept having been brought to life by the Danish bearing manufacturer back in 2015.

What is a hands on review?

'Hands on reviews' are a journalist's first impressions of a piece of kit based on spending some time with it. It may be just a few moments, or a few hours. The important thing is we have been able to play with it ourselves and can give you some sense of what it's like to use, even if it's only an embryonic view.
