Today, Shimano has announced a new mount standard for road disc brakes called Flat Mount. This new mounting option has been developed by Shimano in close cooperation with leading road bike brands as a dedicated “on road” solution. This new design allows bike manufacturers to move away from the mountain bike history and looks that has been used up to this point.
We have no further details at this point, but Shimano did send over these CAD drawings in their press release. Head past the break for a couple of more tidbits from the press release…
Key advantages over current available mountain bike disc mount structures are:
- A cleaner, integrated construction with the frame (no visible mounting bolts)
- A more direct connection to the frame and better alignment (eliminates stacking
- Easier tool access for disc caliper adjustment (even inside rear triangle)
- Backwards compatibility with mountain bike style post mount calipers (with an adapter)
Stay tuned for more information as we get it.
