The Short That Revolutionized Cycling Shorts

In 2007 Castelli introduced the Free Bibshort. It revolutionized cycling shorts with the incredible feeling of freedom it gived. The flat raw-edge Giro leg band and the minimalist Free bib construction have since shown up on virtually every high-end short in the market. And the Free became the best-selling short in Castelli history.

For 2015 we’ve re-engineered every detail of the Free while keeping everything you love. Our best race short is now both more comfortable and more aerodynamic. We wanted to make it perfect, so we tore down every component of the Free: every fabric, every construction method, every stitch.

Muscle Support and Speed

In re-engineering the Free we took a look at blood flow, giving just the right muscle support without constricting. The revolutionary Giro Air leg band gives more stretch and distributes the compression over a larger area. The body of the short uses 30% Lycra® for excellent return.

We also looked at aerodynamics, optimizing boundary-layer airflow with the Giro Air leg band and the dimples on the side fabric. The wind tunnel says it saves 10 watts at 50 km/h, but you’ll probably want to go even faster because your aero advantage will only increase.

Obsession With Comfort

The best race short must be supremely comfortable. The new fabrics are all softer than the outgoing fabrics, especially the new softer surface fabric on the updated Progetto X2 Air seatpad. The innovative double V construction on the front keeps everything in place without compressing your stomach. And we’ve engineered a new Carré yoke that makes the straps lie perfectly flat.

But the most important part of comfort is fit. As one of our pro testers said, “These shorts fit perfectly. They don’t move around. Everything is just right.”

The 2015 Free Aero Race short. An unfair advantage. 

  • Vortex dimpled fabric on legs for aero performance
  • Forza fabric on inner legs with 38% Lycra® content for perfect fit
  • Carré engineered lie-flat bib strap construction for minimal coverage, maximum comfort
  • GiroAir mesh-like leg gripper elastic for better grip distributed over larger area
  • Doppio V construction in front for increased support and comfort
  • Flat-lock stitching
  • Reflective detailing on back
  • New improved Progetto X2 Air seat pad for even greater comfort
  • Race radio pocket
