DQITJ 2 Pack Brake Bracket Adapter MTB Bicycle Mounting Holder 20mm and 31.8mm Disc Brake Bracket Bicycle Components (160mm)

They worked good

Amazing how you could use these on just about every bike that has disc brakes

I was going to adapt my rim brake bike to disc brake. Already have a disc wheel but the bracket can't be bent to fit my curved front fork. I can most likely cut it and weld it to my steel fork but was planning on doing a suspension fork swap so I'll test cutting and welding the bracket after I mount up the other fork just to see if I can do it. Caveat: the bracket seems a little week to rely on it for the front brake and I have doubts that it's strong enough to stand up to hard breaking.I have a high confidence of being able to mount and use the rear brake adapter so the purchase of 2 brackets is not a total loss.

I think that this design is simple and very sturdy to secure the disc brake caliper to your fork. But.... it takes modification and fitting by you to be able to make it fit. I needed to measure, fit, drill, file, trip(s) to hardware store to get nuts/bolts to be able to make it fit and work. Definitely not a drop-in part !

I have been wanting to build my own electric scooter and had a bunch of bike part to work with. I got these adaptors so the 20 inch wheels I had would work on the 26 inch cruiser frame I wanted to use. They took a little figuring out but once you test fit them a couple of times it is easy. Make sure you look at the two adaptors they give you one is for the front and one is for the rear brakes. the nature of the mounting bands left a bit of slop in the mount so I had to shim to make sure the mounts would not shift when braking. wish the mounting bands where adjustable but will experiment on next build.

Doesn't fit most frames, is way too wobbly and the distance from it to the rotor is off, so not usable in any way.

the metal is thin, i had to use both pieces to make a bracket thick enough to be trustworthy. as-is, this is a terrible idea to bolt-on anywhere. but the parts worked perfect for a disc-equipped bmx bike. flipflop hub, and disc adapter. i needed steel to complement the steel bike frame, and this worked great after some cutting and welding. a whole lot easier than cutting out my own.

Does not work for bikes with smaller bars.
