Description Bottoms up.
The Shimano MT800 Threaded Bottom Bracket uses smaller bearings like those found on XTR and Dura Ace bottom brackets for less drag, and better sealing means you get more time riding and less time creaking. It's designed for use with 24 mm spindles like those found on Deore XT M8000 Hollowtech II cranks.
Compatible with 68 mm and 73 mm English-threaded bottom bracket shells. Includes two 2.5 mm spacers and installation adapter for bottom bracket tools designed for standard 44 mm external diameter cups.
