Used to bleed brakes on new Ultegra 12 speed build. The kit works flawlessly. The price is high but it will make your life much easier than using a cheap off brand kit from Amazon.
Using this kit to bleed bleed GRX800 and Ultegra R8070 road hydraulic disk brakes. You need to buy the R9120 adapter for the funnel and the RS505 bleed block to use the kit. Iï¿½m guessing that Shimano put this kit together for mountain bikes. Thereï¿½s no road bike specific kit that Iï¿½m aware of.
