This is the bottom bracket that specifically fits the Fifteen.G crankset from The Hive. It uses a 6806 bearing, standard in BB30 systems. The bearings use a 9% larger ball diameter than standard external bearing systems. This increase in size gives a 16% increase in load capacity, therefore increasing the durability of the bottom bracket. The cups are made of 7050 aluminum and are CNC machined, polished, and clear anodized. As with all of their threaded components, the torque specs are laser etched right onto the part for easy assembly. The Fifteen.G External Bottom Bracket comes with five 1mm shims and a wave washer for the bearing preload setup. It also comes with three 2.5mm spacers to accommodate fitment to both 68 and 73mm English threaded BB shells. You will need the Fifteen.G installation tool or a 1-3/4" 12-point socket to install or remove the cups.

Please note: the cups on the Fifteen.G bottom bracket are larger than standard diameter. So if you plan on running an ISCG mounted chainguide, check with the guide manufacturer for compatibility.
