Expensive but effective

- Bart, 28 September, 2025

Works fine. Thanks to this extra piece, you can mount a larger disc brake rotor. It takes some puzzling how to do it exactly, but it worked fine.

Expensive but useful piece of steel

- Alwin, 27 August, 2023

Once ordered a similar block via ali when these were never available in corona times, always messing about with rear brakes shifting with hard braking and far too soft steel, so screwing harder wouldn't work either. Now got these and totally no more problems. Brake nicely straight away, nothing shifts under full braking. An expensive part, of course.

Pros & Cons

Actually works
Had to look up manual myself

Superb part, will now feel much safer on long descents.

- Peter, 31 May, 2021

I had a 140 rear brake disc on my new race bike, more than enough for in flat Flanders. However, I wanted to fit a 160 rear brake disc for the Alps. On Mantel's advice, I was able to fit a 160 brake disc with this flat mount adaptor. Have already tested it out in the hills. It fits perfectly.

Pros & Cons

fits perfectly
good manual included
expensive for a small part
