These are a pair of Ultegra 6770 STI Brake / Shift Levers from the Ultegra 6700 range.

They are Di2 and work with both 10 and 11 speed systems with the correct software update.

Braking is by cable, they are not hydraulic.

Bought new by me they've seen plenty of use but still work perfectly.

Both levers have scrapes to the ends. This damage can be seen in the photos.

Any questions, please ask.
