It’s got your back while you ride ahead. Varia™ eRTL615 rearview radar for eBikes is our first battery-free radar. It plugs directly into your compatible eBike. It detects cars approaching from behind and provides audible and visible alerts when paired with your compatible Garmin smartwatch, bike computer or even your smartphone with the Varia™ app. This radar also has a bright tail light to make you more visible to motorists, adding peace of mind to every ride. And since you don’t have to charge it between rides, that’s one less thing to worry about.

Your tires are the only thing connecting you to the road or trail, and having optimal tire pressure can have more impact on ride comfort than both frame and wheel choice combined. But finding the right tire pressure requires trial and error. TyreWiz is the first-of-its-kind tire pressure sensor for riders of gravel bikes and road bikes, taking the guesswork out of finding that optimal tire pressure. Lightweight and durable, TyreWiz adds only 10 grams to your tires. With an IPX7 waterproof and dustproof rating, you can confidently ride on any type of trail and know that your tire pressure sensor will keep going strong. TyreWiz reports data with +/-2% accuracy at a resolution of .1 PSI; vastly more accurate than any tire pump on the market. TyreWiz monitors the air pressure in real-time and relays the data to a cycling computer or a smartphone. That information is relayed to the SRAM AXS app and delivers personalized recommendations and pressure alerts. TyreWiz gives riders access to highly accurate, real-time tire pressure data to make decisions that can affect rolling resistance, traction, tire wear, and rider comfort. Features - Designed for road and gravel riders. - Personalized tire recommendations in the smartphone app for iOS and Android. - Data reported with +/- 2% accuracy at .1 PSI resolution. - Broadly compatible with tires that use a removable Presta-style valve core. - Inexpensive, user-replaceable CR1632 battery lasts for 300 hours. - IPX7 dustproof/waterproof rating. - Box includes valve-core removal tool for installation.

It gives you the option to run without a heart rate monitor chest strap. Once paired with your compatible smartwatch, just clip it to the back and center of your waistband and start your run. Review Your Form View and analyze important running metrics such as your cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio. These biomechanical measurements can help you understand your running form so you can perform better on race day. How It Works: The Running Dynamics Pod has an accelerometer in the module that measures torso movement to calculate these 6 running metrics: - Cadence is the number of steps per minute. It displays the total steps (right and left combined). - Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right. - Stride length is the length of your stride from 1 footfall to the next. It is measured in meters. - Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters for each step. - Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form. - Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.
