CASTELLI Superleggera bib shorts

For our lightest-ever road short, we use the first seamless graduated-ventilation stretch woven fabric to make a short that´s both impossibly light and cool yet supportive for the longest rides.

LIGHT, COOL AND STRAIGHT OUT OF THE FUTURE.

We´ve been pushing the envelope on lightweight shorts since 2011 but have butted up against the limits of compromising durability for ever lighter weight.

We needed to step back and find a better way.

We examined what the short really needs to do:

it needs to hold the seat pad securely in place while otherwise adding as little weight or fabric as absolutely necessary (without being transparent, obviously), and it needs to last a season of hard use.

So we engineered a brand-new fabric using a woven rather than a knit that shaves 30% in weight for the same level of support and non-transparency.

Then we worked with the world´s leading mill to construct a gradient fabric that becomes increasingly lighter the farther down the leg it extends, with the last part weighing a mere 90 g/m2 compared to normal short fabric, which weighs around 220 g/m2.

This fabric, while being insanely light, maintains a decent durability along with excellent abrasion resistance, at least against the saddle.

We don´t guarantee it against unplanned slides across the asphalt, so please keep the rubber side down!.

Note that while the short saves a mere 48 grams while dry, this means it also absorbs around 30% less moisture when you´re sweating.

So when you´re sweating your way up the Alpe d´Huez you´re actually saving closer to 150 grams.

This short doesn´t compromise on comfort.

We use our top Progetto X2 Air Seamless seat pad, the spectacular striped mesh bibs from the Free Aero Race 4 Bibshort and a flat stretch woven leg gripper to keep everything in place.

But it´s the finishing that sets this short apart.

The logos are embossed into the surface of the fabric for a very discreet rich tone-on-tone effect.

With this short you don´t need brightly colored logos to shout out that you´ve achieved the ultimate in cycling comfort and performance.
