Shimano Ultegra ST-R8170 Di2 Hydraulic Disc Shift-Brake Lever
Ultegra's 12-speed wireless Di2 lever brings Dura-Ace shifting features and Servo Wave disc braking for a little more weight and a lot less money. Available as a lever alone or as a pre-bled set with the BR-R8170 calliper.
Highlights
Why we rate it
Same shape as Dura-Ace
The hood and lever geometry mirror the R9270, so the ergonomics are identical at a lower price.
Servo Wave brakes
Fast pad engagement and strong, controllable stopping in all weathers.
Programmable hood button
A third button on top of the hood can be set up in E-Tube for shifting or head unit control.
Satellite switch port
Plug in SW-RS801 sprint, climbing or aero-bar switches for extra shift points.
Simple maintenance
One CR1632 coin cell per lever and an easy-bleed hydraulic system.

Sachet Instructions
1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.
2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
7. Go clean that filthy bike!
