The Truvativ GXP bottom bracket is a high performance, external bearing bottom bracket. The GXP system captures the left side bearing between the spindle and the left crankarm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long lasting ride and SRAM’s gutter seal technology drastically improves sealing against the elements while reducing seal drag.
  • For 68/73mm BB shells
  • Gutter Seal Technology
  • Improved tool engagement
  • Sealed cartridge bearings

Comments about SRAM Blackbox GXP Ceramic Bottom Bracket:

It comes with plenty of the ceramic grease you need and the confidence inspiring blackbox brand behind it. Super smooth and efficient for crushing the pedals. Coupled with some XO1 cranks and you have a hell of a set up.

Standard GXP BB always had a growl sound to it. This bottom bracket eliminated the noise and spins more freely now. Got it on sale at a great price.

      Comments about SRAM Blackbox GXP Ceramic Bottom Bracket:

      Did not think a bottom bracket could be so smooth and add a "lightness" to my pedal stroke. Has been performing flawlessly for a few hundred miles. Looking forward to see how it holds up long term.

        Comments about SRAM Blackbox GXP Ceramic Bottom Bracket:

        I have about 150 miles on this bottom bracket in good weather so it's hard to say how well it will hold-up but at this point I am very happy with it. I had a ceramic BB before but I could not get it to stop creaking even after re-greasing and tighening, (non-SRAM). I finally gave-up and bought the SRAM BB. Glad I did.
