My bike is currently in the shop, I had a Stages non-drive PM arm installed and now the Stages crank arm contacts the Shimano direct mount brake, the shop sells Cannondale's says that because of the way the bottom bracket area is designed that they don't know of any other options for a rear brake that will work with the this bike, has anyone installed another direct mount brake on a late model Slice, would a Omega X work?

They tried installing this one but it wouldn't work
