Star-Art 20/31.8mm Adjustable MTB Bike Disc Brake Bracket Converter Frame Adapter Mounting Holder (20mm)

Flimsy

Have a 90's Ritchy steel frame mountain bike. Nothing better than steel. Works well. Have it with Shimano hydraulic brakes. I have hit these hard no change in back stays, and this bracket keeps wiggling its tail. Light weight too.

I knew this could possibly be not worth the money, unfortunately I was right. The material is too thin, the holes do not really align, and the overall design is just poor.

Didn’t end up using it for its I tended purpose, I cut the lower half off to make a fender bracket adaptor for my springer forks to be able to use the stock nel lusso fender. Which it was great for. As a brake caliper bracket it’s ok but I wouldn’t use it where it was a primary brake as one bent on me and caused my caliper to fall into the disc and severely warp the disc rendering it useless.

I haven't had a problem with this bracket it stands the test of time recommendable!

Doesn't work at all. Multiple bikes and multiple attempts only resulted in scratched forks and bent discs.

Go for it if you need to mount disc brakes on the rear

In the process of converting an ancient Trek mountain bike to E-pedal assist, needed bracket to mount a new front disk brake to replace the v-brake I had been using. Ordered this adapter and found that the angle of the dropout slot did not match my front fork, the metal band was not sized to match the front fork tube and the anchor slot that was supposed to be secured between the inside of the front fork and the axle boss would not work unless I changed the axle from quick release to bolt secured. So, I used this bracket as a template to fabricate a usable part from flat steel stock that would work on my bike. I used it to position the disk brake mounting holes and the holes for the metal band and built a bracket that would mount outside the fork axle dropout that I could actually secure with a bolt, and I fabricated a new mounting band as well. Bottom line, it is likely that you will have to do some modification to either the bracket or your bike for it to work.
