So you got yourself a 12-speed Di2 bike, or an older one with the Di2 Wireless Unit and have set up your head unit to display the currently selected gears. That’s pretty cool, I agree! What would be even better is the ability to get a nice report of your gear shifts. On this page, I’ll tell you how to do that!
Using the Wahoo Element companion app
If you ride with a Wireless Unit or display enabled there’s not much you have to do. Just pair it to your Wahoo Element (or Garmin, Sigma, etc.) and it’ll automatically record shifting data for you. Then, after a ride, open the ride results page. All your gear shifts are right there.
The exact implementation differs per device manufacturer, for Wahoo users it looks like this:
Have the Wireless Unit paired but don’t see the GEARS display on the results screen? Scroll down to the bottom of the page and tap EDIT CARDS. You should then be able to enable/disable the GEARS card.
Di2Stats.com was created in 2014 by Brian Toone, an assistant professor at Samford University. At the time of writing it is the only website that allows you to upload your rides and generate shifting statistics. It’s really simple! After a ride get the .fit file from your device or app and upload it to di2stats.com. It will then work its magic, and generate and display statistics.
Scroll down a bit and you’ll get more detailed shifting information. It’ll display at what point in time you shifted to what gear, when you changed chain ring and how much time you spent in each gear. The website also shows the raw shift data.
SRAM AXS Web
About a year after this article was originally written SRAM joined the party - they launched SRAM AXS Web. Despite the name, this website definitely works with Di2. Have a look at the in-depth article on SRAM AXS Web and Di2 for more information.
