Praxis Shimano T47 Inboard Bottom Bracket
The Praxis Shimano T47 Inboard Bottom Bracket is a T47 bottom bracket designed for Shimano Hollowtech II spindles. It is made using Enduro 2437 bearings and is specifically for Shimano bearing stance. This bottom bracket is available with steel or ceramic bearings and uses machined heat-treated aluminum cups. It is made for frames that can accept a T47 inboard bottom bracket, meaning the bearings sit within the frame.
This bottom bracket requires the Praxis T47 I.B. Shimano Tool for installation and removal.
