These are now available!!
Had my LBS ring hope as they were not on their B2B site, got it the next day, fitted at the weekend.
No more pad clearance than sram or shimano as youve still got the same lever travel. Looks very pretty and came with everything needed to fit, olive, barb, pads, pad spacers, etc. Need to bed the pads in properly still before i can say for cetrain but lovely smooth power so far.
Worth noting they do 3 versions for SRAM and Shimano (so 6 really)
Post mount
Flat mount rear (160mm rotor without adaptor)
Flat mount front (160mm rotor without adaptor)
The flat mount are different to the stock sram/shimano as you cant fit 4 pistons, stock position and 140mm rotor, so they’ve had to design different calipers for front and back.
(edit)Just found a BikeRumour article with more detail
