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

Great Upgrade

I've used it several times

I have ceramic bearings in my Cannondale frame but GPX ceramic is unbelievably smooth......and unlike the other first 75 mile ride on the new Pinarello F8 (see another review) with the new BB was so good kept looking at the crank! Worth the extra money!

Solid Bottom Bracket

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.

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!!

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.

Breaking in a bottom bracket makes as much sense as buying a 100% organic steel bike frame. Both instances use words in the English language but not in any recognizable or logical way.


One supplier claims the bearings used here are made by Ceramic speed. Can you verify this? Same quality as their Name brand product? Thanks, Sandy D.
