Fast. Smooth. Durable.

SRAM’s GXP Blackbox Ceramic Bottom Bracket features ceramic bearing technology, making it one the smoothest, most efficient bottom brackets on the market. In addition to being lighter than standard bearings, SRAM’s ceramic bearings use a more rounded cut to reduce mechanical drag and create optimal power transfer. Also, these durable ceramic bearings are more resistant to moisture and dirt, which means this bottom bracket will perform season after season. The GXP Blackbox Ceramic Bottom Bracket has alloy cups, anodized in Red, and is designed to work with all SRAM road cranksets.

  • Made with silicon nitride ceramic balls in sealed cartridge bearings
  • Ceramic bearings are lighter and more efficient than standard bearings
  • Ceramic bearings use a more rounded cut to reduce mechanical drag
  • Compatible with all SRAM road cranksets

Solid Bottom Bracket

  • Familiarity:I've put it through the wringer

First of all, I probably should have read the product description in more detail because the product I received was the red anodized color (not the depicted silver color). However, color wasn't a huge issue for me. So I slapped this on my bike, and haven't regretted it yet. I can say this was a solid upgrade from the Sram GXP Team BB.



  • Familiarity:I've put it through the wringer

I'm not 100% sure what "breaking it in" means, but I've used ceramic BBs since they were available (one of the most cost effective upgrades you can make IMHO) and have owned one of these for years. It's worked flawlessly since day 1 and I wouldn't hesitate to recommend.


Don't buy!!

  • Familiarity:I've used it once or twice and have initial impressions

If you have loads of time on your hands to "break it in" then by all means spend the $200.00, otherwise do not buy it. My old BB was way better and in fact I just had the shop put it back in until I have time to burn breaking in this waste of money.
