Rotor’s UBB 4630mm 386EVO Threaded Bottom Bracket with steel bearings solves some of the issues which can plague PressFit bottom brackets by having the two cups threaded securely into a central sleeve.

This sleeve holds the cups in the correct alignment which prevents premature bearing wear and stops internal cable guides from contacting the rotating bottom bracket.

Rotor UBB 4630mm 386EVO Threaded Bottom Bracket - Steel

The UBB 4630mm 386EVO Threaded Bottom Bracket with steel bearings from Rotor is designed for use with Rotor 3d+ 3d30 and all Rotor Power cranks that have a 30mm spindle. The outer cups screw securely onto the central sleeve which holds them in the correct alignment thus preventing wear and increasing the lifespan of the bearings. The sleeve also keeps the axle separate from any internal cable guides and reduces the creaking that can be an issue with normal PressFit bottom brackets.

  • Threaded sleeve locks PressFit cups in place
  • Increases bearing life
  • Protects bottom bracket and cable guide contact
  • Steel bearings
  • Fits 30mm axle cranks; Rotor 3d+ 3d30 and all Rotor Power cranks
