Hollowtech To GXP Bottom Bracket Replacement

Just did a Hollowtech To GXP Bottom Bracket Replacement for the Cervelo P2 using the Sunlite Tool BB Hollowtech2 / GXP Wrench. FYI, the GXP & Hollowtech shares the same wrench configuration but the BBs are not interchangeable due to the size of the opening (Inner Diameter) of the GXP (SRAM) which is smaller than the Hollowtech (Shimano) BBs. At least that is true when I tried to insert the Shimano 105 Crankset after removing the SRAM Red Exogram crank which won't go though the left side BB. However I am still unsure the usage of the Plastic cap that comes with the wrench.
