Shimano Flat Mount Disc Brake Adapter reviews and deals for sale

If You Are Building Your Own Bike...

I ordered a frame set and couldn’t figure out at first how to fit a 160mm rotor on the rear of my bike with the Shimano Dura Ace right/rear brake caliper shifter combo. Then I found this handy little adapter. The left/front shifter caliper set comes with an adapter that can be flipped to fit the 140mm or 160mm rotor.

Excellent

Fit and function were excellent

Worked as advertised

Converted my 140mm rear rotor on a BMC Roadmachine 01 to 160mm so I could interchange wheels from several bikes. Easy to install. No worries here.

Adaptive

If you need to fit post-mount calipers onto a flat-mount frameset, these little adapters are the way to go. The end result might not look as clean as using a flat-mount caliper, but I'm more than happy to make that compromise if it lets me save the few hundred dollars a new brake system would cost.

Life Saver

So I just got a new gravel bike and the ENVE Gravel road fork that came on the frame is the new flat mount standard. The SRAM RED Hydraulic disc brake set that I have is a post mount. I really did not want to buy a new caliper for this new standard, admittedly it would have a cleaner look if I used a flat mount caliper, but I really did not want to shell out extra cash. In comes… read more the Shimano flat mount disc brake adapter to the rescue. I picked up the 160mm "Front Post to Flat" adapter and voila! Everything was right in the world again.

Does this come with the snap ring to support the bottom of the caliper as outlined in the manual?

The description indicates that this adapter allows for installing a flat-mount caliper on a post-mount frame. Is this true? If so, which ones would I need for front and rear? "Post to flat" to me would mean you have post calipers you need to install on a flat frame, so I was looking for an item called "flat to post"--but do I have this backwards? Thanks in advance.
