With the flat-mount standard, the disc brake Responsorium frame features newly-designed dropouts, a redesigned rear triangle, a mandatory English-standard bottom bracket to provide space to house the rear brake cable and a new version of the Falz fork featuring the same gently curving design as its rim-brake cousin. Both disc options accept tires up to 28mm in width.
Pegoretti originally developed the Falz fork because there was nothing on the market that was either up to the task, or looked elegant enough to complement our frames. So when designing the disc-brake Falz, they were careful to carry over the same flowing design aesthetic, despite the fact that the blades are reinforced.
