Our review

Some great features, but also some love/hate ones and not the best value
Skip to view product specifications

Knog’s most function-rich NERD is expensive for the amount of data delivered, but its easy operation and unique looks will find fans. It uses Knog’s signature ‘hard device inside coloured silicone skin’ design for both the head unit and wireless fork sensor, which can quickly look grubby.


The head can be rotated to work on your bar or stem, and shifting modes by pressing the whole unit rather than fumbling for a button is perfect for cold hands or rough trails. The two-line display uses big, chunky digits and set-up is simple and intuitive. But the bulged fish-eye effect and slow-scrolling speed display numbers are as love/hate as the overall looks. Considering the data both this and the cheaper NERD 9 deliver, you’re definitely paying a premium for the quirky design.
