shimano Hollowtech bottom brackets are quite common on modern road bikes, although other systems are regularly seen too. Shimano Hollowtech Bottom Brackets are fairly simple to remove and fit, although a special tool is required to remove the cranks. When replacing the cranks, make sure they are securely fastened, as a damaged pair can be expensive to replace.
