Before mechanical approach, remember to read and follow the manufacturer’s indications of the bottom bracket. You must first removing the BB30 bottom bracket.

The dismantling demonstration is performed on a frame Specialized S-Works Tarmac SL4 with turnover in 2012 SRAM Red BB30. Here the bearings are encapsulated in plastic fur (bowls) covering the frame (the carbon cage). Other arrangements are possible depending on the brand managers. Instead of plastic, the bearing may abut on a retaining circlip inserted within the cage in which a specific groove FIG.

So we have four elements: Two plastic boxes (bowls) and two bearings.

For information, if bearings are loose or make noise, we advise you to change rather than trying to do any manipulation. A damaged bearing should be changed!

Install the bike in a bike stand.

Strap it properly at the bottom bracket.

Please have a bearing extractor. (You can find the reference of it in our list of tools needed at the top of the article)

  • Insert the head in the cage of the case. If the bottom bracket uses a snap ring, be sure to orient the head of the tool so do not hang.
  • Up close
  • The tool should be inserted into the horizontal
  • The opposite side, it has come to rest in the middle of the bearing so that the bearing of the tool is in contact with the inside of the bearing
  • Use the plastic outer end of the tool so that it serves to guide resting on the bearing by which the tool has been introduced.
  • Strike a sharp blow with a hammer. Attention bearings are fragile. The shock must be open and the tool must be perfectly aligned horizontally.
  • Across the entire basin stands with working within it. The cleverest will keep rolling and the tool with one hand on impact so that turnover fell.
  • It is now responsible for the second bearing. Place and insert the tool where the first bearing is extracted, and this, in the same manner as before. The plastic can be inserted into the cage to provide guidance / stabilizer to keep the horizontal tool.
  • Strike a sharp blow with a hammer. Attention bearings are fragile.
  • The Entire bowl stands with working within it.
  • To extract the bearing basins hold the tool as shown below. The litters are on the bearing.
  • Strike a sharp blow with a hammer. Attention bearings are fragile.
  • The rolling out of its housing.
  • It is cleaved from the bowl
  • The ride is free.
  • Wipe by removing fat from the bottom bracket cage.
  • It’s over !
