Read how to set up your two-adjustment-bolt Di2 Front derailleur (6870, 9070)
Front derailleur (2x10)
This first generation Ultegra Di2 Front Deraileur can be used on 2x10 Di2 builds. Note that it will not work on triple setups.
It is meant to be used with a chain line of 43.5mm. Recommended top gear teeth range is 50-56T and its total capacity is 16T
Originally this derailleur could be used together with an 11-speed rear derailleur, but that functionality was later removed in a firmware update. You can not longer use different speed derailleurs on the same bike.
If you are using one of these with an 11 speed rear derailleur I strongly recommend you do not update its firmware.

Did you know that you can mix Di2 components from different series and categories? Mixing derailleurs is not recommended, but anything else is fair game!
