The Wahoo ELEMNT just started shipping this week, but already they’ve added a new trick to its bag. Or, tricks (plural) to be more precise. The device will now hear from your Shimano Di2 or SRAM eTAP group and display gear selection on the screen. You’ll need Shimano’s D-Fly wireless transmitter for it to work with that group, but SRAM’s eTAP group should work with it right out of the box.
And with ANT+, Bluetooth Smart and WiFi, it should talk to just about anything else you’ve got, too. That includes the newest of performance biometric measuring devices capturing Blood Oxygenation. Also known as SmO2, there’s also a spot for showing tHb (total hemoglobin). Thus far, that means devices from BSXinsight and Moxy Monitor, but others are out there or coming. That metric shows how quickly your muscles are recovering from an effort and when they’re fully gassed up for the next interval. Hit the links for a more detailed explanation. Retail is $329.99 for the ELEMNT computer.
There’s also a slick new RPM Speed sensor and more…
Wahoo’s RPM Cadence sensor now comes in a smaller, sleeker and all-black package, and the price has dropped to $39.99. If your phone or a Polar head unit is the hub of your cycling intelligence, this Bluetooth accessory is all you need to get pedaling cadence. But, it also sends info in ANT+, sharing that same info with any modern cycling computer.
Completing the picture is the new RPM Speed sensor, which attaches to your front wheel’s hub and calculates your bike’s speed based on its RsPM. Why would you need this when your phone can figure speed through GPS? One, it could save your phone’s battery life. Two, it’s more accurate, particularly if there’s a lot of tree cover or tall buildings on your route. It also broadcasts in BT and ANT+ and retails for $39.99. Or get the bundle with both Speed and Cadence sensors for $69.99.
