Brake Bracket Adapter 2pcs(160/20mm & 160/31.8mm),Disc Brake Bracket Converter Bike Components & Parts

It works but it’s flimsy

Do you want those fancy new disc brakes, but only have an old bike frame built for rim brakes? These are what you need. This set has one bracket for the front and one for the rear. Clamp them on, and line up with the drop outs, then you have brackets to install disc brake calipers on. You will of course need the calipers and wheels that support disc brakes too, but these are a start.My chief complaints are these. The rear brackets clamp is too wide. I had to find something to fill the empty space in order to get a firm clamp down. The front has the threads on the wrong side of the clamp, meaning to screw the clamp down, you have to screw it in through the spokes of the wheel, rather than from the outside. Had both sides of the clamp been threaded, there would have been more options for how to install. The front is also conversely VERY tight. It was hard to get on there, but at least once it's on it has a solid mount. The disc brakes themselves worked quite well from these adapter brackets,s o they certainly do their job. Just be warned that not all bike frames are the same shape and size, so be prepared to get creative in order to make them line up correctly.

Going to add hydrolic brakes to a bike that never had disk to begin with this is going to be great!!!!!

DO NOT BUY UNLESS YOU HAVE EXTENSIVE MECHANIC AND MACHINIST EXPERIENCE AND TOOLS!!!These are basically pieces of metal punched out in roughly the correct shape to get a project started. They're cheaper and slightly faster than designing, cutting, drilling, and bending chunks of metal yourself. Unless you have a drill press, belt sander, taps, bolts, rubber, and the knowledge and experience to basically completely change these from how they arrive into what you'll need based on the bike you'll be putting them on, this isn't for you. They are NOT EASY TO INSTALL!!!!I had to cut an old tube to make the rubber inserts for the securing brackets. Because of how small my frame and forks were, I had to also heavily modify the brackets by re-bending them extensively, cutting them, and even drilling one of them.The caliper brackets themselves also needed extensive modification, both arrived bent the wrong direction to fit either fork or frame, and I had to completely bend them the opposite direction and multiple times fitting, and re-fitting with a caliper to mock up. The front I had to drill an additional hole to bolt onto the fork itself, and then also tap the holes for the securing bracket, then drill and sand the mounting bracket.With how much I had to do, took me about 4-5 hours to finally get a mock up that seems to be ready to work, I still have to repaint everything before I finalize it, and I still have yet to get the brakes up and going yet as of writing this. Just know that whoever said these are easy to install, functional, and a good value either got extremely lucky and should buy a lottery ticket, or is lying.

Not a good fit at all. It may work on a BMX bike? Did not work on my mountain bike. Had to fabricate my own. Plus mine looks way better.

First off, those who had issues did not install the item correctly. There is a difference between front and rear adapter. Use the wrong one and failure will happen. Secondly, there is exactly one and only one way to install these. If you get the orientation wrong or install backwards, then it will fail!Lastly, This is most important. You will have to modify the bracket! No way around that fact. For me, I had to bend and twist the bracket to get it in the right orientation and proper placement using a heavy duty bench vise. (Any vice will do, in reality) Just do not do it while installed on the bike. I also had to use a dremel tool to cut the screw bolts as they are too long and is a packaging part error in reality that has never been caught. I screwed the strap down until the bolt touched the brake rotor then used the dremel to shorten length of the screw bolt to provide plenty of space.FYI, use a large diameter washer behind the bracket to prevent possible torsion failure that some have had installing the bracket backwards. This type of torsion failure is possible correct orientation and the washer will prevent the bracket from spreading its seated mouth. If you install correctly and do the modifications, it works as advertised. This will take someone hours if not all day to install if you are mechanically inclined. Defends on bicycle brand and type as to how much you have to modify. If you do not know much about tools and are not mechanically inclined, then my advise is take it to someone and pay them the $30 to $50 to install it for you. OR, you make make this a project to learn how to use a bench vise and do metal bending. However long it take you will be good experience down the road.I gave it 3 stars because it does work as advertised. However, I will not give it top rating because it is not a bolt on out of the box item. You have to spend hours to modify, cut and adjust to get it to work.

Good

Increíble fits on old bikes to convert to disc brakes. Dislikes: taxes!!!
