The BB-5500 is the Octalink bottom bracket from Shimano's older 105 road group. It is a sealed cartridge unit with a hollow steel spindle, so the bearings and axle go in as one piece and the splined crank arms locate straight onto the spindle ends.
This is the 68 mm English-thread version with a 109.5 mm axle. It suits the original Octalink (V1) road cranks, such as the 105 FC-5500, Ultegra FC-6500 and Dura-Ace FC-7700 series, so check your crank model, your shell width and your thread before you order.
