Kogel T47 M30 Road Seal Ceramic Bottom Bracket

Kogel T47 M30 Road Seal Ceramic Bottom Bracket This Kogel Road Seal ceramic bottom bracket is compatible with T47 threaded; 85.5mm or 86.5mm wide bottom bracket frame shells and cranksets that have an M30 spindle. The cups are hard-wearing; thread easily into the frame and house grade 3; super smooth spinning ceramic ball bearings. These bearings are tough; so won’t deform or crack over time; run on polished steel races and have road cycling specific seals to further lower friction. Kogel’s BB Boost design format is integrated into this bottom bracket to position the bearings as closely as possible to the crank arms; heightening stiffness and durability.
