Read how to set up your two-adjustment-bolt Di2 Front derailleur (6870, 9070)
The Shimano FD-6870-F is a braze-on road Di2 front derailleur that can also be mounted using a clamp. It weighs 138.5 g and supports a top gear maximum of 46T-53T & total capacity of 16T.
When used with the BT-DN110 battery, the 6870 derailleurs are also synchronized shift capable. This front derailleur doesn't allow for as much flexibility as the newer ones do though.
Read more on that in my complete guide to synchronized shift.
