The RCP Bottom Bracket B.B. wrench is essential for the assembly or loosening of bottom brackets. The long stable lever exerts reliable pressure on the fixed bearing shells. The mutli-tooth tool fits precisely on all standard bottom bracket shells, whether they be multi-tooth, square or hollow axis system eg. SRAM or Shimano.
A clever detail is the integrated special keys for assembly and disassembly of the safety screw on the current Shimano Hollowtech 2 crankset.
