Premio 2 Bib Short

Premio means "prize" in Italian which is a fitting name for Castelli's bib short which sits at the top of its podium. Now in its second generation, the Premio 2 Bib Short is the fruit of the years of labor spent working in the lab, on the saddle, and with pros to make the best short even more comfortable. It utilizes high-stretch Forza fabric with a 38-percent Lycra content for a super soft next-to-skin feel with excellent compressive qualities that never feels binding.

Its nearly seamless construction is derived from its Body Paint shorts, which debuted a decade ago and ushered in the trend of shorts with reduced seams and refined fits. As such, shorts today are less likely to chafe and are more durable. Handling sitting duties is the renowned Progetto X2 Air Seamless chamois with a new skin care layer and a remarkably soft surface fabric with more stretch that allows Castelli to eliminate the front triangle.

No small detail went unnoticed from the new bib construction with a mesh back and a bonded 2-layer bib straps to the new silicone Castelli logos that stretch with the base fabric. A dual-layer lumbar support band keeps the shorts locked in place around the waist while raw-edge leg openings with vertical silicone grippers keep the hem in place during the entire duration of your ride without compensating on the stretch.

  • Castell's top-tier racing short built with long-milage comfort
  • Forza fabric with 38% Lycra content ensures a perfect fit
  • Reduced seams improves fit, comfort, and durability
  • Raw-edge leg ending and vertical silicone grippers keep hem in place
  • Mesh back with bonded 2-layer bib straps support comfortably
  • Silicone Castelli logos stretch with the fabric
  • Progetto X2 Air Seamless chamois supports and cushions
  • Dual-layer lumbar support band keeps shorts locked in place around the waist

Chamois delight

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: L

Castelli pushes their seamless chamois, but the the key is the free-floating top layer of fabric that acts as a second skin to prevent chafing.

The leg gripper grips extremely well, perhaps too well, I have to pull it into place. But once it's there it doesn't move.

Top of the line chamois are 10% better than their cheaper cousins, but over the course of 70 miles, that 10% makes the extra investment worth it.

For tall and thin cyclists, the straps will be tight when you first put the bibs on, but I don't notice them once I'm in the saddle.... and they have seemed to loosen up over time.

In short (pun intended), these are well-made bibs that (with embrocation) won't chafe on long rides.

very comfortable

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Maybe it's just because I haven't tried new chamois recently, but I was surprised at how comfortable these were when I rode them yesterday. At first they felt a little slippery on the saddle - not having the same tacky traction to hold in place as other bibs - but this proved to be a blessing (if you're not in a TT) after I got used to it.

Fit: felt borderline too tight at first but actually fell in love with the mild compression, with the exception of it around the waist (the bibs have a bit more structure/elastic higher up around the waste than others I've tried). I got the "short" model and the legs still felt on the long end of the spectrum for me.

Where did you find a "short" model?

Perfect Bibs

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: M

These are my favorite shorts to ride in. The bibs are sewn with less panels so the fit is more exact than the aero race. I like and prefer the fit of the Premio over that of the aero race. I did not have to size up. The shorts are a bit overkill for commuting. I especially use them for racing and for race training rides. They are more supportive and give a feeling of confidence when on the rivet. The pad is much better than the previous rossa corsa. The straps are wide and are made from a thicker material. When riding over time the shorts help you feel less fatigued. They 100% help me feel freshest at the end of a race. I wear a medium in these, the aero race, and everything else Castelli. They are worth it, highly recommend.

Great Bib Shorts

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: XL

Fits great, but I think it runs a bit small. (I usually wear a L but that was too tight for me so I upsized to an WL and it fits great.). Chamois is terrific and rides well. Bib straps are a little tight when standing, but are perfect when riding. I highly recommend.

How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.
