Description

Look fast to go fast.

If you want to see what happens when you mash up some of our favorite bib shorts with Competitive Cyclist styling and livery, look no further than the Women's Competitive Cyclist Aero Race Bib Short from Castelli. It pairs top-notch materials, with a fit that's refined for day-long rides honed from its decade's experience of providing the sport's best riders with kits. And just like we've seen in bicycle frame design, these shorts give the nod towards aerodynamics and are constructed to help you slice through the wind a little easier letting you go faster with less effort. Of course, these would all be moot points if they weren’t comfortable to wear, but thankfully Castelli specs it's women's specific Progetto X2 Air Donna chamois for support and comfort.

The Aero in the name gives a hint as to the design queues Castelli instills into these bibs. It claims a reduction of power output in the neighborhood of 10 watts at 50 kilometers an hour. The secret to these gains comes from how the shorts manage airflow across their layers and textures especially the Vortex fabric dimpling on the shorts' outer thigh. Just like with a golf ball or some deep carbon rims, these dimples manage the turbulent lamina of air that runs along the shorts' surface, preventing its premature release into pockets of drag-inducing dead air. This is complemented with its stretchy Forza fabric on the inner legs which incorporates 38% Lycra to easily follow your every move and provide gentle compression.

Chamois duties are handled by the excellent Progetto X2 Air Donna insert with offers a super soft face fabric next to your sensitive areas. It retains its anti-microbial properties, seamless construction, four-way stretch, and a ventilated, perforated foam layer. A quick poll at the office has Castelli's chamois right up there with some of our favorites and our go-to shorts if we know we're in for a long ride.

The bibs' uppers feature a wide-open design that still lends support while preventing you from overheating. They feature a unique strap construction comprised of two different materials. The straps are mesh 3/4 of the way up while its Carré material cradles your shoulders. Carré is a soft, seamless strap that lies flat against your skin, so there aren't any wind-grabbing ridges from bib straps under your jersey. The seam between the mesh and Carré is reinforced, so the junction remains together after repeated wearing and washings.

The Giro Air leg grippers provide a mesh-like elastic that lies perfectly flat, offers tenacious stay-in-place grip, and a low mass helping to reduce the aerodynamic footprint. The band is also wide, spreading the pressure over a larger area and offer more gripping so hems don't move about on your ride.

  • Competitive Cyclist branded shorts for fast riding and racing
  • Dimpled Vortex fabric offers free speed with aero qualities
  • Lycra-boosted inner legs ensure you can dial a perfect fit
  • Lie-flat bib straps provide total comfort with minimal coverage
  • Flat-lock stitching reduces chaffing potential
  • Progetto X2 Air Donna chamois cushions you on rough roads
  • Lock your hems in place with Giro Air mesh-like grippers
  • Boost your low-light visibility with reflective accents
