This Lezyne GPS Is Like Crack for GPS Data Junkies

Remember the days when the purple route line was just a highlighter stripe on a paper Michelin map? My old Polar CS200 had everything I needed before the days of GPS cycling. Then a particular company got us hooked on the GPS crack. And we all dropped a carbon wheelset’s worth of cash to see a grainy picture on our stems of the next 2.0 miles of our rides. Then topo maps. Gradients. Road databases. So much data—Rand-McNally right there under our sweat-dripping noses. You want data? You gotta pay for it. Until now.

Enter the Lezyne GPS. If you can still call a device that tracks your location on the surface of the earth from over 13,000 miles away “minimalist,” this is the embodiment. So is the price tag. Ranging from Mini to Power to Super GPS, Lezyne leaves off the map, but maximizes function and value. Want numbers? They have all the numbers you need.

Speed, time, elevation, time of day, lap splits, plus you can Bluetooth or ANT in your heart rate, speed, cadence, and power meters to bike-nerd it all out. On the Super GPS you can even Bluetooth in your phone and get text, email, and call alerts. Is your jersey pocket vibrating because Junior’s school office is calling or because work is saying “Lunch is over”? No need to guess. They have their own GPS Ally app for iOS and Android, plus they can auto-sync to the ubiquitous Strava for the ultimate social bike-geek data experience. But wait, it gets better. I have used the Super GPS for a whole month before recharging the battery. Watts for days.

So, what is wrong with the unit? Small stuff. You can only sync one activity at a time. No problem if you are always connected. If you go off the data grid for an epic week, well, you will have to take a few extra minutes uploading each gnar ride individually. The other downside? The bluetooth phone connection is somewhat finicky when switching between devices. I ran the Lezyne for a week on my phone connection with no problems. Then I let my wife try it out for a while. Getting it to switch between hers and my phone for alerts was a little trying and cumbersome, so, stick with what works first for you out of the box.

Bottom line, if you want to experience your ride and see the map later, look no further. Even if you have to adhere to a Zone-3 Over/Under 1 minute ON 1 minute OFF regiment, ” target=”_blank”>Lezyne still has you dialed. Look at the rocks now and the map later. Enjoy your ride. Outside is Free.

Editor’s Note: Lezyne responded to our article with a couple of tips on pairing.

Try these in this order:
Make sure the device has the latest firmware:
With the Super GPS plugged in, delete the “” file from the device. This will reset any screen customization, but reset all connections too. We’ve found this to help when pairing to a new phone.
Make sure the phone has the latest Ally app update, and unpair any existing Lezyne GPS devices in the phone’s bluetooth setting. Then toggle the Bluetooth off and on.
Then, try pairing to the Super GPS through the phone’s Bluetooth settings, rather than through the Lezyne App

I know this sounds like a lot of effort, but it’s really the nature of Bluetooth. It will become more reliable and robust over time, however.

Review: Pioneer Power Meter Gives You All the Data

It feels odd to have Pioneer in the power meter market since they’re known for making things like car entertainment systems and DJ equipment. But I was excited nonetheless to see a giant box show up one day with their power meter mated to a Shimano Dura-Ace 9000 crankset as well as a Pioneer SGX-CA500 computer.

Installation on my 2010 Colnago CX-1 was fairly straight forward, provided you RTFM’d, and props to Pioneer for producing an informative installation video. As soon as I had it installed, I was off, and I’ve been using it steadily over the past few months. So far the system has worked flawlessly, minus a few hiccups that were solved by replacing the battery.

The SGX-CA500 is as big as my camera card reader, but I do like its size - It's just right.

The SGX-CA500 computer has also been easy to use and allows you to navigate via the touchscreen or with physical buttons. You don’t necessarily have to use the Pioneer computer—the power meter will pair with any ANT+ computer—but they work nicely together and help unlock the full array of metrics the Pioneer system is capable of producing.

I particularly liked that the Pioneer computer shows left and right leg output, and pedaling efficiency, live. It’s a neat feature and it helped me realize that I need to improve on my pedaling technique. Thanks to the built-in wifi, your workouts can be automatically uploaded after a ride.

CycloSphere, like Garmin’s Garmin Connect, is Pioneer’s online cloud platform where your data gets stored. It’s a treasure trove of information, but not super easy to use. I liked that you can customize what you see in CycloSphere, and I suspect it will get better over time as the Pioneer system gets more popular. Note to Pioneer: as you make improvements, I want to be able to configure my SGX-CA500 settings while plugged into my computer for better visualization.

Currently, the system is limited to Shimano Dura Ace and Ultegra level cranks. At $1,849 for the Dura-Ace power meter and $299 for the computer, it’s not cheap. But if you’re into data, you should take a look. For those who already own a Shimano Dura-Ace 9000 and Ultegra 6800 crankset, Pioneer offers an installation service, where you can ship your existing crankarms in to be converted. This is less expensive at $999.
