High quality BB set for T47 Internal type BB shell of 85.5~86.5mm such as New Madone, Emonda & Domane. Sugino OX series and Shimano hollowtech?cranks (DURA-ACE, ULTEGRA, 105) work perfectly with the BB.

Frame standard : T47 Internal
BB shell width : 85.5~86.5mm

Advanced sealing mechanism including special lip seal gives long term durability in water and dust, ensures longer service life of high precision bearing. So, service and maintenance of the bearing are not required.

Easy installation and removal
Due to thin flanges on T47 cups, a wrench may slip off and damage the bottom bracket and frame. The special tool T”L-PWS86” which matches the cup perfectly, makes installation and removal easy, and facilitates the maintenance of the internal cable.

For braze-on style front derailleurs, you will need MT-OX to run front chainrings smaller than conventional 50/34 combination.
