Easy greasy.

Keep your BB spinning like new or swap out heavy-duty grease for lightweight lube with the Chris King Bottom Bracket Grease Injection Tool. Compatible with all Chris King Bottom Brackets, push-type grease guns, and universal-fitting grease guns, the Injection Tool simultaneously purges old grease and inserts shiny new grease to keep your cranks spinning smoothly. Use it several times and it'll more than pay for itself, and you won't have to worry about investing in a new bottom bracket for decades, if you're careful.

  • Aluminum
  • Compatible with push-type grease guns and universal-fitting grease guns
  • Zerk fitting included

Here's what others have to say...

Is this for the 24mm or the 30mm bottom bracket?


Pretty sure this is for the 24mm. The other is listed as "Chris King 30mm injector" specifically.

Great Tool

  • Familiarity:I've put it through the wringer

Extremely great tool, chris king would hit a home run adding this addition to there bottom bracket, makes changing grease a snap!


Nice to have

    I like to do it myself instead of paying someone else. Good to freshen up the bearings every once in a while, and there is no point in buying quality gear and then failing to maintain it properly. Also, the silver nipple is a Zerk fitting that works with the Speedplay grease gun's Zerk adaptor.
