Endurance 2 Bib Short

The Endurance 2 Bib Short from Castelli combines its much-lauded Progetto X2 Air Seamless chamois for all-day riding comfort with the amazingly luxuriously Giro3 lie flat leg gripper at the openings keeping the hem locked in place. It's constructed of its Endurance Evolution fabric that sits softly against the skin while supporting the muscles with optimal compression that’s further complemented with textured compression side panels. It also helps keep you cooler and drier thanks to its excellent wicking properties and superior moisture management. This bib is always up to the task of providing riding comfort on you hardest and longest training rides.

Castelli updates the bib strap construction with mesh back and straps that's designed to keep you cool on those extended summer climbs. Its embossed Castelli wordmark adds a touch on elegance and is well recognized among discerning cyclists.

Poor Seam Placement

  • Familiarity: I've used it several times

Pros: Great Chamois padding, good fit, decent price
Cons: Not so flat seam located mid-line right where your soft bit is located, chamois coverage doesn't cover the fatal seam rubbing on your soft bit, near sheer panels.
I do not recommend these bib shorts.

Runs way small

  • Familiarity: I returned this product before using it
  • Fit: Runs small

Euro sizing - order at least one size up or you'll be singing soprano. Tried on at LBS and one size up still way too tight. Chamois seemed nice but never got to ride on it. Adios, Castelli you don't fit us 'normal' folks..

Good, but not the most comfortable

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 3XL

I bought these in 3XL and wear a 38-40 waist in jeans. They look great, but I'm not in love with the fit. I like my shorts to be midway up my thigh, and these are a little longer. The bibs are a more narrow and not as comfy as the ones on my Rapha or La Passione bibs, but they're not uncomfortable. They're really good. They're just not awesome.

Husband loves these!!!

    This bib is my husband’s favorite. He swears with the comfort and fit. Castelli bike wear are expensive but it’s worth the price.

    I really wanted to like these

    • Familiarity: I returned this product before using it
    • Size Bought: Large

    I though the chamois was well designed, and the fit was good, but the see-through panels on the side from the leg to the top of the glutes put me off.

    I completely agree. The shorts are great and the pad is good even for Castelli, but the see-thru panels are awful. My wife was like, "Are you serious?" and she's a cyclists and gets it.
    WTH were they thinking?

    Sizing too small

    • Fit: Runs small
    • Size Bought: XL

    These are built for thin bodies. The XL wouldn't get over my thighs, made for long lean folks not short stout guys like me. Great looking quality, just not for my size. Bought Specialized XL Bibs at LBS and they fit fine.

    I have larger quads and these bibs take a little more time to put on than others I've had. I like them, but I don't love them.

    not able to use

    • Fit: Runs small
    • Size Bought: xl

    My go to size for Castelli/Sportful bibs is XL, but these were so tight I wouldn't be able to pedal. Hardly could pull them on. Will return and try sizing up. 6'2" 190
