The TT/Triathlon Dual Control Levers ST-6871 is a dual button design for bikes with double chain-rings. Your left brake lever has two buttons that control the front derailleur and the right controls the rear. The Di2 electronic shifting ensures effortless and perfect shifting every time. The alloy levers feature an adjustable reach.
These shifters are compatible with carbon fiber handlebars (but only with aluminum inserts where the brake levers are installed) or aluminum handlebars. The handle inner diameter is 19.0 – 22.5mm and the handle outer diameter is 22.2 – 24.0mm.
I had these shifters on my Cervelo S5 that was modified for Time-Trials (TT) until I was Hit n Run from behind during a training ride. They were undamaged but not usable for my new Tri-bike setup.
Stored carefully. Also have Di2 battery, chargers and other components for sale on a separate posts.
