Shimano Dura-Ace ST-7900 Dual Control Levers

The new STI Dual Control levers offer a refined ergonomic shape while reducing the weight by over 40 grams. With a Shimano first, the new STI levers offer unidirectional carbon fiber lever blades which reduce weight and offer shift cables hidden under the handlebar tape for a more sleek design. Using a revised internal mechanism along with PTFE lined casing, the shifting is still as light as ever.

Shifting stroke for the rear derailleur has been reduced by 20% for quicker shifts and a built in reach adjuster allows for fine tuning the fit for riders with smaller hands.

The shifters continue to have integrated controls for the all new FlightDeck computer (SC-7900), which has been updated to include heart rate, altitude, grade, cadence, gear position, and directly downloadable data via a wireless connection. The new SC-7900 is completely wireless.
