Have a sexy tri bike? Good. Want to make it even sexier? How about adding the Shimano R671 Di2 Aero Shifters? If you thought the jump from a road bike to a tri bike felt like cheating, just wait until you feel the jump from mechanical to electronic shifting. Featuring double button controls so you can shift from your aero position with the push of a button, the Di2 Aero Shifter allows for fast, accurate, effortless shifts. Plus, you have the option of getting satellite controls for the base bar, so you can shift from either position. How sexy is that?
Multiple control positions mean shifts are always close at hand
Fast, accurate, effortless shifts SW-9071 (single-button controls minimize movements for maximum aero efficiency)
Double and single button controls on aero bar shifters
proper use of these shifters will require a 3 or 5 port front junction to connect with the rest of the system
whenever adding new components to your Di2 system make sure your firmware is up to date (see you local Shimano Service Center)
