Soudal/Quick Step Competizione 2 Bibshort - Men's

What Our Gearhead® Experts Are Saying:

"The Competizione 2 Bibshort has become my default for anything over three hours. The KISS Air2 chamois holds up through the back half of a big ride in a way that cheaper pads simply do not, and the Vortex V2 legs have a snappy, race-ready feel that makes you want to push harder even when the legs are telling you otherwise."

The Castelli Soudal Quick Step Competizione 2 Bibshort exists because Castelli understands that the gap between pro race kit and everyday training gear does not have to be as wide as it often is. This short was engineered by working directly from the top of the Castelli bib short range, isolating the technologies and construction decisions that deliver the most measurable impact on comfort and performance and building them into a package priced for the rider who trains seriously and races when the calendar allows. The pattern engineering team at Castelli drove the fit development, producing a short that sits and moves correctly from the first ride without any adaptation period.

Vortex V2 textured fabric across the legs applies the aerodynamic surface treatment Castelli refined for WorldTour competition, creating meaningful drag reduction that accumulates across the full length of hard efforts and long-distance rides. Pro Lycra on the inside leg provides a stretch and rebound profile engineered for sustained power output, maintaining consistent compression and structural integrity through the complete pedal stroke even as fatigue sets in over multi-hour efforts. The combination produces a leg panel that responds to the rider rather than resisting them, across climbs, flat sections, and sprint efforts alike.

The KISS Air2 chamois sits just below Castelli's flagship seat pad in the product hierarchy and delivers the density, coverage, and multi-hour comfort profile needed for both training and competition use. The updated bib strap system combines lightweight elastic straps with a full mesh back panel engineered to keep airflow moving across the torso during sustained warm-weather efforts and high-intensity training blocks. The GIRO4 leg gripper integrates a raw edge finish with silicone stripes to hold position reliably across varied terrain without compression or migration. Flat-lock stitching eliminates raised seam edges at every friction point, and reflective detailing on the back provides low-light visibility for early morning and late evening riding. Made in Italy to the construction standards that define Castelli's standing in the peloton.
