【Name】 One -in -one sealing bearing central axis

【Weight】0.35Kg

[Advantage 1] This bottom bracket uses sealed bearings, which are not comparable to the cheap bearings used by ordinary small manufacturers. There is almost no squeaking noise after one month of riding. The quality and benefits are second.

[Advantage 2] The workmanship, high-quality waterproof performance, and smooth riding effect are in the square hole bottom bracket. Cycling enthusiasts all know this. As for why the tooth cup on the other side of the bottom bracket uses a plastic tooth cup, it may be to make it easier to fit the bottom bracket tooth pattern of the frame and increase the sealing and waterproof performance of the tooth pattern, making it more reliable when riding.

[Note] When purchasing, please make a note of the length of the bottom bracket to avoid sending the wrong product. If there is no note, it will not be shipped!
