Cannondale IQ400 Dual Wireless 18 function computer



An easy to use computer packed with functions including cadence, but the screen isn't the clearest

The Cannondale IQ400 Dual Wireless 18 function computer is very easy to set up. From opening the box to hitting the road took no more than 10 minutes. The instructions are clear and the computer is easy to operate, meaning you don't need to be a tech whizz to use it.

Let's start with the bit you spend most of you time staring at, the computer unit. It's very compact and takes up the minimum of space, small enough to fit on a short stem. The mount allows it to be fitted to handlebars. There's just a single button at the bottom of the screen, cycling through the different functions. It displays three functions at a time. Speed and cadence are always displayed, and you can choose another to be shown below.

Owing to its small size, it's not always that easy to read the display when riding. I feel they could have made better use of the available screen real estate to make some of the lettering a bit bigger.

The computer twists into the mount, it's very secure and won't be bounced out of it by accident. The bottom of the unit hides the set button, this is used to reset the trip computers and stored ride data before your next ride.

Battery life is extremely good. You don't need to remember to switch it off, it does that automatically after half an hour. After five minutes it goes to half power.

You get all the usual functions; current, average, comparison and maximum speed, clock, trip distance, odometer and current, average and maximum cadence. The cadence unit, a small unit that zip ties to the chainstay and also provides the speed information, is a very useful addition if you want to focus on your pedalling technique, in particular the speed of your pedalling.

The only thing missing really is heart rate, and at this price you might expect to get such an addition. And there are cheaper computers with as many functions.
