Prologue Fonzaso SL
The bike for life—premium titanium with modern tire clearance and custom geometry for every rider.

Key Highlights

• Build Material
  3AL/2.5V butted titanium tubing for the ideal blend of comfort, durability, and ride feedback—even if it costs a few extra grams over carbon.
• Direct-Mount Discs
  Engineered for 160 mm rotors and cantilever clearance, giving you powerful stopping in all conditions.
• 30 mm Tire Ready
  Room for up to 30 mm rubber to smooth out rough pavement, chip-seal, or light gravel without sacrificing agility.
• Fully Custom Geometry
  From 4’10” through 6’11” and every stack/reach in between—no stock-size compromises.
• Lifetime Durability
  Titanium’s corrosion resistance and fatigue life make this frame the last you’ll ever need.

Why “Fonzaso”?

Named for the tranquil Italian village where Prologue’s founder perfected his craft alongside Sportful, the Fonzaso Disc embodies old-world road-riding soul and modern precision engineering—ready to be your lifelong ride, on every surface.
