What Our Gearhead® Experts Are Saying: "I wear the Competizione 2 Bibshort for just about every kind of ride. The KISS Air2 pad is super comfortable, even on century days, and the mix of fabrics balances muscle support with breathability. It’s aero where it needs to be, but still really comfortable." From tempo training rides to endurance weekends, the Castelli Competizione 2 Bibshort delivers the comfort and performance we need to ride hard and recover happy. Designed with a mix of aerodynamic and high-stretch fabrics, this bib blends Castelli’s racing heritage with real-world wearability—giving us pro-level tech that’s easy to love on daily rides. The Affinity Pro Lycra® on the inner leg provides smooth stretch and muscle support, while the Vortex V2 textured outer panels help cheat the wind on fast flats. The GIRO4 leg grippers sit flat and stay put, with raw-cut edges for low-profile comfort and silicone stripes for grip. The KISS Air2 chamois adds plush, breathable support, and reflective elements offer a touch of visibility for early rollouts and twilight spins.
