Garmin Edge 705

If you want cutting-edge computing power then you have to look at Garmin’s latest GPS-enabled baby. First thing you’ll realise is that this is a big piece of kit even compared to the old 305.

However, while it definitely takes up a lot of space on the bars, it sits on top of a stem well without getting in the way. You also get a spare mount for a second bike included.

Once you’ve mounted the optional cadence meter, it’s just a case of pressing the ‘on’ button and waiting for it to find enough satellites to centre itself.

You can then choose a full-feature GPS navigation display, a topographic trace, a completely customisable multi-function bike computer screen or mixed display.

We know other users have had various glitches with their units, though, and you’ll have to add a £79.99 Micro SD card to get full GPS functionality.
