Cervelo's "Floating" RDH: Small part, big benefits

Usability
Our RDH was developed to reconcile incredibly tight engineering tolerances with our manufacturing processes. How tight? The two rear dropouts must be parallel (or “flat”) to within 0.1mm of the bottom-bracket’s outside face. The top and bottom brake surfaces need to be similarly perpendicular to the dropout face, and the thru-axle holes must remain perpendicular to the dropout face as well.
