Shimano Ultegra Di2 ST-R8150 STI Brake/Shift Lever Combination For Rim Brakes

Get ready for the “Science of Speed”!

With the Ultegra ST-R8150 Di2 brake/shift lever combination, SHIMANO also paves the way into the 12-speed age for fans of classic rim brakes. The ST-R8150 brake/shift levers, which have been completely redesigned, are compatible with the electronic Di2 12-speed components and use the familiar Di2 cabling. That’s why there is one more slot than with the wireless version. This way you have different cabling options and you can still integrate additional satellite switches into the cockpit.

Of course, the Ultegra ST-R8150 also offers the option of customising shifter assignments and synchronising rear and front derailleur in different modes. Define the gears at which the front derailleur automatically shifts, or let the rear derailleur make compensating shifts as soon as you operate the front derailleur. Shifting through several gears with a long click is possible, too. Effortless gear changes become a matter of course and you can focus your full attention on the race.
