Brake Caliper Type	Post Mount
Mount | Rotor Size	Rear Flat | 140 Rotor

Using this Shimano caliper adaptor is easy. First, make sure you have a 74mm caliper on a Flat Mount frame and a 140mm rotor. Then, use the included mounting hardware to install the adaptor. When installing, follow the instructions carefully to ensure a proper fit. Remember, this adaptor won't work with Avid BB5 or BB7 Calipers. If you have those, use 160mm rotors and a suitable adaptor. For maintenance, regularly check the mounting hardware to make sure it's tight. Clean the adaptor and rotor with a mild cleaner to keep them in good condition. This will help ensure the best performance and a long lifespan for your bike's braking system.
