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.
