Good tool for more serious cyclists
on 24 July 2014
If you've got a compatible (ANT+) GPS device (that perhaps you use for running) and want to add some bells and whistles for cycling this is a relatively cheap way of doing it. It offers speed and cadence via two magnets (one on the pedal and one on a spoke) and a small device that attaches to the frame.
Fitting is straightforward but needs to be aligned properly so worth searching online as there are a number of video clips that will guide you. Once fitted, the watch will automatically recognise the device in the same way as it would a Heart Rate strap. All you then need to do is to alter your display to show the cadence and speed fields and go cycling!
Most devices will already have the ability to pick up speed via GPS so this will replace that calculation. The benefit being that it should be more accurate and faster to respond (not having to rely on a GPS signal from 13,000 miles above us) and also works on a turbo trainer indoors if that's your thing.
Cadence is simply the speed at which you're turning the pedals. So why does it matter? From a personal perspective, it's helped me to use the gears better. Average cyclists tend to have a cadence of around 60 RPM, the pros average around 80. What I found was that on my setup 70 was about right and the way to achieve that was to use lower gears which was easier on my legs (so improving endurance) and my overall speed has increased as I'm using my muscle power more efficiently. I therefore tend to try to keep my cadence at 70 or above now rather than focus on going as fast as I can.
So for me a good purchase that has enhanced my cycling and gives me more stats to pore over afterwards!
