ZTTO Gravel Road Bike Brake Adapter Flat Mount 34mm 71mm To Post Mount 74mm 140mm 160mm Rotor Bicycle Caliper Converter
Created: February 02, 2025The reviewer discusses the ZTTO flat mount to post mount adapters when installing brakes on their gravel bike build. They mention using these adapters to convert the frame's flat mount system to accommodate post mount brakes, which are standard for mountain bikes. The reviewer notes the adapters came with pre-greased screws, making installation easier. However, they encounter a significant issue where the rear brake adapter doesn't fit properly with the frame, causing the brake to sit crooked. This forces them to purchase a Shimano GRX brake instead. The front brake adapter works correctly, but the rear compatibility issue is a major drawback.
AI-Summary
Pros
- Adapters came with pre-greased screws
- Front brake adapter worked correctly
Cons
- Rear brake adapter did not fit properly with the frame
- Caused the rear brake to sit crooked
- Not clearly specified in product descriptions about compatibility issues

- Converts flat mount to post mount system
- Used for mixing road/gravel and mountain bike components
- 34mm 71mm to post mount 74mm 140mm 160mm rotor compatibility
