The Castelli Superleggera bib short is the ideal cycling shorts to use during the hottest days of summer. The fabric used by Castelli is the Gradient Stretch Woven material which is extremely lightweight but still gives enough support to the muscles during cycling. The braces are also made from extremely thin mesh to keep the trousers as light and breathable as possible. This makes them suitable for use in temperatures of up to 40 degrees. Saving weight is a key factor, as the Castelli Superleggera is up to 50% lighter than regular short trousers. Even the Castelli logo has been thought of to keep the trousers as airy as possible. The logo is not put on the trousers as is often done, but is embossed in the trouser leg so that it stretches well and contributes to the breathability of the trousers.
The grippers at the trouser legs are integrated and ensure that the trousers stay nicely in place. To complete the cycling shorts without compromising on comfort, this Castelli Superleggera bibshort is equipped with the Castelli Progetto X2 Air chamois.

Castelli Progetto X2 Air chamois
The Castelli Progetto X2 Air pad is the ideal pad when you make long rides on your bike. This pad is designed to protect your skin and has the right thickness to protect you regardless of your time in the saddle. The top layer is made of microfibre that can stretch in 4 directions and has no seams to create minimal friction while cycling. The foam used has been perforated by Castelli to make it breathable. The chamois has two different layers so you will be better supported in the places where you need it.

Not really happy
- Marc 21 July 2023
											Better mention that you should definitely take 1 size bigger with these trousers compared to other brands
Pros & Cons
 Chamois feels very good
																																																																 For a 3 XL, these trousers come out very small

Super light indeed
- Erwin 26 December 2021
											Bought these for indoor training (zwift). Had to go one size up though, normally with my size 31 an L is enough but it was really too tight, the XL fit much better. It's my first Castelli so can't really compare, but for training sessions of +- 1 hour on the tacx, I am very satisfied with it.
