BBT-16 Self-Extracting Crank Cap Tool

Removing the 16mm extractor cap on SRAM and Race Face cranks typically involves using a large and cumbersome 16mm hex wrench that can be awkward to use because to get the most leverage you either have to remove the pedal or make 3/4 turns. The Park BBT-16 is a wing shaped wrench that removes and installs the self-extracting/one-key release caps on SRAM and RaceFace cranks with a 16mm hex hole. BBT-16 is made from investment cast steel and an option to use 8mm hex should you need a little help breaking it loose.

• 16mm hex for SRAM and Race Face cranks
• Investment cast steel construction
• Can be used with 8mm hex wrench for added leverage
