What flat mounts for my shimano 105 calipers?

I have a new 105 11sp 7020 groupset which has come with flat mount calipers, but no mounts.

Its going onto a new Mason Definition which is 140mm native flatmount frame and forks.

What mounts and bolts do i need to buy so i can use 160mm discs?

Thanks

Ian

Forks take a standard reversible mount. It's 140 one way up. Rotate it 180 degrees and it's 160.

Rear is 140 standard so you need a 160 flat mount adaptor.

Make sure you've got the right bolt lengths according to what Mason specify - I have a Definition and seem to remember the bolts that came with the brakes/adaptors were too long I think, which risks not working, stripping the threads or even death
