It’s rare for us to use the phrase “women’s cycling.” It has weird overtones somehow, likely born out of a time when “women’s specific design” was equivalent to let’s dumb this down and put sparkles on it. That’s changing. Which is why the Signature Fly collection (bibs, knickers, tights) are really the hallmark of design in women’s cycling. When temps turn cooler, ride comfort calls for a bib knicker, but until now, that meant taking off a helmet to pee or using a product that compromised on ride quality.

The Superfly Bib Knicker begins with the foundation of our Signature Fly Bib Short, complete with an easy-on / easy-off, mid-ride bathroom break option. (No halters. No oddly placed seams. No jersey, helmet and sunglasses removal.) The zipper from which it takes its name can’t be felt while pedaling and isn’t used while regularly dressing or undressing.

It’s not all about mid ride nature breaks, however. The coverage below the knee is light and protective avoiding the need for knee warmers and emphasizing fit. The unique bib upper now includes lightweight straps bordering its stabilizing mesh panel, a construction designed to rid the ride of chaffing and to bring a lighter overall feel to the bib.

Supportive and light-feeling, these are knickers designed from the ground up to meet the highest standards of performance, and to make the cool-weather mid-ride stop as short as possible.

Fit Note: The Signature Fly Bib Knicker bears a highly compressive fit for excellent muscle support and recovery. If you prefer a more relaxed fit, we recommend sizing up.

How does it work?

Chest - Start by placing a measuring tape around the largest part of your chest. The tape should be flat but not too snug.

Waist - Your natural waist lies between your bottom ribs and hip bones, close to the navel. To measure, breathe deeply, relax your stomach and lie the tape measure flat around your waist, allowing for a ¼ inch of slack.

Hips - To achieve the most accurate hip measurement, find the widest point of your hips and place the measuring tape around. The hip bone often isn't the widest point - it's one to two inches lower, where your butt is at its fullest.

    The perfect knicker for shoulder season days. Very comfortable and sleek! I had never worn knickers until Velocio made these high tech ones. Love the zipper in the back, it lays flat and isn’t bulky, and allows record time pee breaks!

    After being disappointed with some Rapha knickers, I decided to try these instead and I’m so glad I did! The material is great, the chamois is super comfortable and doesn’t chafe me and the straps are stretchy enough that they fit well over my shoulders. The back zip feature, while a bit awkward to use (I wish it went down 1″ farther), is the best solution to the ladies bibs/bathroom issue I’ve seen. I don’t feel the zipper while riding. I found them to be true to size. I am 5’7″, 135 lbs, slim through the hips/butt and the small fits perfectly. I’ve been wearing them non stop since I bought them =)

    I have just spent a month cycle touring in Italy and wore these every single day. I washed them every night and because of the beautiful light fabric they dried every time just hanging in our room without a drier. They are beautiful to wear, have withstood constant use with no sign of wear, have the best chamois ever and the bib is very comfortable. The zip idea is fantastic. I could not recommend these highly enough. The weather was quite warm in the daytime not hot, mid 20’s c and they were very comfortable.
