The difference between integrated bearings and traditional bearings
Hello, the typical representatives of hollow integrated cranksets are Shimano’s mid-to-high-end series, sora level and above.
The ordinary bearings you are talking about are generally square hole center shafts.
The characteristics of the hollow one are that it is very light (compared to the square hole), has high rigidity, and is easy to disassemble.
Ordinary square holes are widely used in recreational vehicles and low-end mountain and road vehicles.
The square hole bottom bracket has its axis fixed on the frame and requires special tools to remove it. Its rigidity is lower than that of a hollow one.
