HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency. HollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability. Use TLFC37 or TLFC25 in conjunction with TLFC36 adaptor tool for installation and removal For use with Ultegra - 105 - CX70 chainwheels
With Di2 technology shifting is easy and precise - just a light touch as soft as a mouse click is sufficient for the front or rear derailleur to instantaneously select the correct gear The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates corrosion and stretching and also provides effortless gear shifts Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold TT / Triathlon two button bar end shift switches are used to operate both front and rear derailleur's Can be used on there own direct into SMEW90 junction or in conjunction with STI TT / Triathlon bar end shift switches give the added option of being able to operate the gears from two positions either these aero extension or the STI lever while under braking which is only possible on a Di2 TT set up Shifters are supplied with 600 mm electrical cables installed For use with E-tube systems Weight is 95 grams a pair
