0.87 Inch / 22mm Mountain Bike Disc Brake Frame Adapter Mounting Holder, Bicycle Disc Brake Conversion Brackets Suitable for BMX MTB

If you are getting this for a razor mx350 and are getting brakes that have a adapter on them you will need a 180mm rotor

Did not fit my front forks they gave me the wrong size so I have used them before and they worked well but I had to make my own front fork connection at a heavier metal the metal they use isn't really that strong and the last time I used one like this the metal crumpled. So as aftermarket caliber connectors go it's okay but not great I know they make heavier ones but I've given up on putting a disc brake on the front of my electric bike I went with clamp types

Works as it should

This adapter did not work for me, I think because of the bicycle frame size. I cut it and welded it to the frame

Bought to sets for two different setups and they worked like a charm for both brake setups.

Worked awesome but I do weld them on other wise they will move. Much better welded on.

It worked on the bicycle by being able to get rid of the cantilever brakes and actually put a disc in the rear however I was expecting something a little bit more substantial just seem kind of cheaply made but it worked out all right

It was the wrong size for my front fork..
