The road bike industry may not be changing to flat mount overnight, but there are bikes out there with the new standard like the Orbea above. New flat mount frames are backwards compatible with post mount disc brakes, but if you have a bike with a new, supposedly better standard, then it would be nice to take advantage of it, right?
Joining the number of brake manufacturers introducing new flat mount compatible designs is Rever. However, Rever’s MCX1 flat mount caliper is one of the first dual piston mechanical disc we know of to be offered in flat mount…
Basically their MCX1, only smaller, the MCX1 flat mount uses a smaller brake pad since the actual caliper is smaller. However, Rever mentions it is still a standard Shimano size pad which will make finding replacements easy. Unlike many mechanical disc brakes, the Rever MCX1 uses a twin moving piston design rather than one fixed and one moving piston.
Currently available for OE customers only, consumer availability is scheduled for mid summer with pricing TBD.
