In Stock
The Shimano Deore BB-MT501 is a threaded Hollowtech II bottom bracket built for reliable, low-friction performance on mountain, gravel and trail bikes. Improved sealing keeps grit and water out, while the smooth-turning bearings help every pedal stroke drive the bike forward.
Highlights
- Hollowtech II interface for Shimano two-piece cranksets with a 24mm steel axle
- English (BSA) threaded fitment for 68mm and 73mm bottom bracket shells
- Anodised aluminium cups for durable, corrosion-resistant threading
- Upgraded sealing for better protection in wet and muddy conditions
- Spacers included to set the correct fit for both shell widths
Built for everyday riding
As part of Shimano's Deore family, the BB-MT501 is engineered for hard-working use on the trail and the daily commute alike. The sealed cartridge bearings spin freely and shrug off the dirt and moisture that wear out lesser bottom brackets.
Easy, secure installation
The aluminium cups thread directly into a standard English-threaded frame and torque up solidly. Supplied spacers let you dial in the correct setup for a 68mm or 73mm shell.
Compatibility & fit
Fits English (BSA) threaded frames with a 68mm or 73mm shell (1.37 inch x 24 TPI). Designed for Shimano Hollowtech II two-piece cranksets with a 24mm steel axle. Confirm your frame uses a threaded BSA shell and that your crankset is a Hollowtech II 24mm type before fitting.
