Reviews & Ratings
08:02The reviewer unboxes and tests a HASSNS brand ceramic bottom bracket purchased from Temu. They describe the initial impressions as positive, noting the metal dust cover (instead of plastic), good seals, and the inclusion of a 22mm reduction spacer for compatibility with Shimano and SRAM GXP cranksets. They immediately encounter a compatibility issue with their 73mm mountain bike frame, as the bottom bracket appears designed for a 68mm shell. They proceed to install it on a vintage road bike with a 68mm shell instead. The installation is straightforward, and they are highly impressed with the smoothness and free-spinning nature of the ceramic bearings, calling it 'Next Level' compared to previous steel bottom brackets. They conclude by showing the product listing on Temu, cautioning viewers to carefully select the correct 'color' (which denotes the ceramic model) and size when ordering.
03:22The reviewer analyzes a ceramic bottom bracket purchased from Temu. They confirm the bearings are ceramic based on their non-shiny, almost transparent appearance compared to steel. The reviewer notes it spins well but suggests the ceramic quality is likely not high-end. They lubricate the bearings with ceramic-specific grease as they arrived with minimal lubrication.
