Garmin is the big player when it comes to using a GPS to track your cycling workouts. Sure, you ttpave a couple of new players such as Polar or Suunto, but they either don’t offer much savings, and they don’t have a lot to offer in the way of new features.
As such, Garmin well-entrenched in the GPS market.
The Sigma brand offers several GPS cyclometers. Their devices are small, discrete and an enjoyable way to impress your friends and say “I have GPS!” (plus, it can be a handy way to find your way back to the car after an all-day effort when the phones are dead, and no one has a clue where they are.)
The Sigma pure GPS looks a lot like a non-GPS bike computer. It is close in size, and the statistics can be scrolled through on the bottom of the screen, just like you would a regular computer.
The simple, three button navigation makes it easy to get through all of the required screens.
The Pure GPS just seems to have a compass to help you navigate, and the onboard altimeter tracks your climbing profile. It can also point you to the shortest distance back to where you started from, ensuring you are never lost.
The value of this computer is that you can sync it to your home computer after the ride, download your performance for safekeeping and share it with your friends.
Since it measures the distance via GPS, you don’t need a wheel sensor and can just mount it to any bike and start riding. It does the rest.
One of the neat features is that with some of the Sigma Sports computers, you can upload your rides from the Sigma Data Center into your Strava profile. This is the entire reason why many cyclists get a GPS — so they can track their rides without bleeding their phone’s battery. Unfortunately, the pure GPS is not a compatible device, and you will need to go with the ROX GPS 7, 10 or 11 to get that feature.
The benefit of going with these nicer models is that you can upload your route to them and it tells you the way to go to stay on the route. These higher-end models can also track your heart rate and even sync to your power meter.
Overall, the pure GPS can be a fun little upgrade for working out. The ability to switch it from bicycle to bicycle without tools is especially attractive.
However, it does seem surprisingly limited to me, especially since it doesn’t upload to any of the biggest ride tracking software on the market.
I’d choose to either go with one of their lower feature-ladened models that can also track altitude and cadence, or upgrade to one of the more hardcore GPS devices they offer.
Or, there is always Garmin. After all, there must be a reason why Garmin continues to be a the top of the peloton after all these years.
