FAQs
Are these shorts suitable for all-day rides?
Yes, the Progetto X² Air seat pad is specifically designed for long-distance comfort and vibration damping.
Do I need to wear underwear under these bibs?
No, these are designed to be worn directly against the skin to prevent chafing and maximize the performance of the seat pad.
How do I determine my correct size?
Consult the Castelli size chart specifically for 'race fit' products, as these are smaller than casual cycling gear.
Can I use these for indoor trainer sessions?
Yes, their excellent breathability and moisture management make them perfect for hot, indoor training environments.
What is the primary benefit of the raw-cut legs?
Raw-cut legs provide a secure, aerodynamic fit without creating the pressure points often caused by heavy silicone grippers.
Is the rear pocket large enough for a smartphone?
The pocket is best suited for small items like gels, bars, or house keys rather than large smartphones.
Troubleshooting
Leg ends curling up during a ride
Ensure the raw-cut fabric is pulled taut against the skin and that no base layer is tucked underneath the leg hem.
Feeling excessive pressure from bib straps
Verify that you have selected the correct size; if the straps pull too hard, you may need a size up to accommodate your torso length.
Fabric irritation after washing
Ensure you are using a mild, non-biological detergent and avoid all fabric softeners.

Setup, Compatibility & Care
To ensure the longevity of your bib shorts, follow these guidelines:
- Fitting: Try the shorts on while in a cycling position, as the fabric is designed to fit best when you are hunched over handlebars.
- Washing: Always machine wash on a delicate cycle (30°C) inside a laundry bag to protect the specialized fabric.
- Drying: Air dry away from direct sunlight; do not tumble dry as heat can degrade the elastic properties of the compression fabric.
- Storage: Avoid prolonged exposure to harsh detergents or fabric softeners, which can strip away the moisture-wicking properties of the material.
- Compatibility: These shorts pair best with high-end jerseys due to their slim profile, ensuring a clean, aerodynamic silhouette.
