Simple, minimal wireless computer that does everything you need without fuss
Skip to view product specifications

This wireless computer has a screen measuring just 33mm x 39mm so it takes up next to no room on your bar or stem, but the display is still big enough for easy reading.


Setting the time and wheel size is a little more fiddly than usual because you have to press a couple of tiny buttons around the back, but at least a pointy button-prodder is provided.

The sensor isn’t especially fussy about spoke magnet positioning, which means you can quickly ziptie it on, and this evens things out.

Once up and running, operation is about as simple as possible – the whole screen is effectively a button that you press to cycle through the information on offer, which is great in a racing, pop-eyed training or technical riding situation.

The nine functions cover all the basic speed and distance essential, and you can add a wired cadence sensor for an extra £9.99 if you want to check your spin speed – a very good value upgrade.

There’s a wired rather than wireless version for £21.99 too, although we reckon it’s well worth paying the extra £8 for the big convenience bonus of cordless transmission.


We got a small amount of signal disturbance from our big LED and from other computer sensors although a quick bit of repositioning cured both issues.
