Shimano XT Hollowtech II Bottom Bracket BB-MT800
Shimano XT Hollowtech II BB-MT800 bottom bracket for XT FC-M8000 cranksets.
The all-new DEORE XT FC-M8000 cranks turn on an updated HOLLOWTECH II press fit (BB-MT800-PA) or threaded (MT800) bottom bracket. Using smaller, lighter bearings and a seal system proven on both XTR and road groups, the new bottom bracket reduces weight and bearing drag while improving mud durability. In short, less weight and increased rotational efficiency results in a faster DEORE XT ride.
BB-Type: HOLLOWTECH II
Threaded BB shell width: 68/73mm
Shell diameter: BSA (BC 1.37)
HOLLOWTECH II Technology
The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
