Frames with an FM160 or FM180 dropout can have a standard Flat Mount 140 caliper mounted directly to the frame without the need for adapters. There are several advantages to FM160/FM180.
- Clean look without adapters.
- Easy to manufacture 1. Caliper to rotor alignment relies on caliper, not the frame.
- Easy to manufacture 2. Frame tolerances are more forgiving.
- Reduced chance of frame damage during installation. Threads are in the caliper, not the frame.
- Reduced chance of brake squeal, direct connection to strong part of frame.
- Easy to mount racks and fenders.
Flat Mount 160 and Flat Mount 180 are a great option for many bikes.

- Cyclocross
- Gravel
- Bikepacking
- E-Bikes
- Touring
