Low Friction Tracking: Features dual molded, ultra-smooth plastic routing channels that guide bare mechanical front and rear derailleur inner shift wires. This design maximizes shifting crispness while preventing the wire from cutting into the raw carbon frame shell.
Cross-Over Layout: Configured to match Wilier’s signature internal down tube routing scheme, safely managing the crossing point of the shift wires beneath the bottom bracket without binding.
Debris Barrier: Acts as a protective shield against road grit, grease, tire spray, and corrosive sweat, keeping the critical bottom junction clean to prevent shift degradation.
