The reviewer mentions using a ZTTO T47 bottom bracket on a bike for about 5-6,000 miles with minimal maintenance in all weathers, and it remains smooth. They note it contains unbranded, no-name bearings, but the internal T47 design provides a more forgiving environment.
AI Summary
Pros
- Has lasted 5-6,000 miles in all weathers with minimal maintenance
- Still spins nice and smooth after that distance
- The internal T47 design shields the bearings better from spray and grime, leading to a longer lifespan for cheap bearings in this format.
Cons
- Contains completely unbranded, no-name bearings
- The bearings themselves are not of higher quality; their longevity is attributed to the frame design.
Key Points
- Used in an internal T47 bottom bracket design
- The internal, threaded T47 design is chunkier, stiffer, and sits inside the frame, reducing flex and axial load on the bearings.
- The design better shields bearings from spray and grime.
- The reviewer states cheaper bottom brackets are more viable in internal, threaded designs like T47.
