AbsoluteBlack has garnered a reputation for its premium and ornate oval chainrings but the British brand has recently begun branching out into ancillary product development. Last year saw the first of these new product lines come to fruition when it added a graphene-based chain lube to its portfolio followed a few months later by a cheaper graphene wax alternative. The big news, however, comes more in the form of the product you see here - the AbsoluteBlack Hollowcage Carbon Ceramic Oversized pulley cage. Positioned to go head-to-head against the oversized pulley wheel segment stalwarts from CeramicSpeed, Kogel, Muc-Off and Token, it doesn't just look superb, it comes with a host of claims to help boost its credibility including best-in-class aerodynamics, decibel reduction and watt savings.

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.
