8. Shimano Ultegra SM-BBR60
If there were a gold standard for bottom brackets, it would look like the SM-BBR60. It is easy to install, and its screwed construction ensures that the ball bearings are perfectly aligned. Additionally, this design reliably eliminates fitting issues caused by excessive manufacturing tolerances, which can occur with press-fit bottom brackets. As a result, the BBR60 does not creak, is compatible with a long list of cranks featuring a 24-millimeter axle, and is not even expensive.
It's no wonder that Shimano's Hollowtech II standard has been in use for what feels like forever. If you are looking for a practically maintenance-free, coordinated bottom bracket-crank system, you cannot overlook Hollowtech II and this bottom bracket.
Hollowtech II refers to a coordinated system of crank and bottom bracket. The cranks with this standard consist of two parts. The right arm is firmly connected to a steel axle with a diameter of 24 millimeters. The crank arms are made of hollow-forged aluminum, which does not result in any weight disadvantage even in the era of highly developed carbon technology. The bottom bracket is matched to the cranks and axles and includes ball bearings with precision seals. This way, no energy is wasted, and you can enjoy your bottom bracket for a long time.
9. Shimano Bb-Mt800pa
The new cranks rotate in a revised Hollowtech II bottom bracket. Thanks to smaller and lighter bearings and a sealing system that has already proven itself with the XTR, the new bottom brackets are both lighter and more rotation-efficient. Therefore, in addition to improved dirt resistance, they also provide more speed.

How can I identify my bottom bracket? Learn more about it.
Does your bike creak when you pedal hard? Is the movement of the crankset no longer smooth or feels loose? The symptoms are clear: it’s time to replace your bottom bracket. Like all parts of your bike, the bottom bracket and especially its bearings are subject to wear. Replacing it is a straightforward process when well-prepared. The variety of bearing, bottom bracket, and frame standards may be daunting to some. We will try to guide you through this jungle of standards. The bottom bracket is the interface between your crankset and your frame. Therefore, you first need to determine which crankset fits which frame.
