SHIMANO Bottom bracket BB-MT800-PA Road, 89.5/92mm

See full product description and bike specification below.
The Shimano XT MT800 bottom bracket features cups that are made from a fibre-reinforced polymer material, which reduces the risk of frame noise and damage. Coming kitted out with a complete XT level press-fit bottom bracket assembly, it's a perfect choice of upgrade for Shimano HollowTech II MTB cranks. Set includes left and right-hand cups, a 2.5mm spacer, an inner cover, and inner O-rings.
