SHIMANO UNVEILS HYDRAULIC ROAD DISCS WITH R785 DI2 SYSTEM & 11-SPEED ULTEGRA DI2! | Bike Rumor


Ultegra 6870 Series group
After months of speculation, leaks, but little actual info, Shimano’s highly anticipated hydraulic road disc brake system is finally here. Oh, and there is a new 11 speed Ultegra Di2 group as well. At this point in the game, Shimano trickling down the new features from Dura Ace 9070 is just about a given, but there are some great updates to an already amazing system. I’ve been on an Ultegra 6770 Di2 equipped bike for the past few months, and riding is believing. With 6870 only promising to be better, the future is looking bright for Shimano electronics – and road discs.

Now for the reason you’re all here – Shimano’s R785 hydraulic system. While you may have been expecting to see a specific Ultegra branded system, the Ultegra-level system allows it to exist on its own, since it’s not a complete drivetrain. The beauty of the ST-R785 shifters and BR-R785 hydraulic disc brakes is that thanks to the E-Tube wiring system, the R785 group can be added to any E-tube equipped Di2 group. That means Dura Ace 9070, new 11 speed Ultegra 6870, and 10 speed Ultegra 6770. We asked Shimano Road Product Manager Dave Lawrence about the cross compatibility, and he said since the rear derailleur essentially tells the shifter what to do, the ST-R785s are basically plug and play for any E-Tube system. He did mention that older 6770 systems that have not been updated recently may need a firmware update, but other than that they will all work together.

By making certain fast, silent and correct shifts, the new re-designed hydraulic brakes options a support bolt that makes a rigid platform and keeps correct alignment whereas moving the chain to the large chain ring.
