Bibs for grownups.
The Mavic Ksyrium Pro Men’s Bib Shorts are the bibs you’ll be after once you’ve graduated from a high chair to high ambitions in the saddle. They’re built to offer serious compressive support for your muscles, so you don’t get unduly exhausted on grueling century-plus days, and they also keep you cool and provide comfortable and ergonomic cushion between you and the road noise filtering up through the seatpost.
Little differences matter over long distances. The panels of the Ksyrium, all of which are made from Skin Matrix ST fabric, are sewn with flatlock seams and aligned to provide ergonomic support while decreasing irritation when you’re moving in the saddle. The fabric itself is compressive and highly breathable, so you don’t get worn down from muscle vibration or turn into a sweaty mess under the hot mountain sun, and then open mesh bibs increase cool, life-giving airflow.
The Ergo 3D Pro Endurance chamois might be the most important part of the entire package. It’s made from dual-density Ortholite memory foam—which feels even more plush than it sounds—and increases shock absorption by up to 20% over standard inserts. The foam also changes shape as you move, so you’ll be completely support whether you’re gearing up for a climb or just out for a long, moderate double century. You know, an easy day.

Great short, great chamios

As a bigger guy, I really appreciate the thicker chamois in the larger sizes (l, XL, XXL). I would agree with the other review that the chamois position lends itself better to a less aggressive fit on the bike, but still felt fine tucked in for long descents. Full disclosure...I'm the product guy for Mavic USA, but these are my go to bib shorts!
Like the cut. The chamois is ok.
- Familiarity: I've used it several times
There's a lot to like about these bibs. The cut is comfortable when in the riding position and the straps are soft, breathable, and don't twist up as easily as Castelli straps do. It's also low enough in the front not to restrict your diaphragm and to make breaks a little easier. Sizing is mostly true to size for me. I wouldn't mind if there were a little more compression, but it's adequate. For reference I have a 34" waist and the medium fit me fine. I tried a large too, and would probably go for those if I wanted a more relaxed fit.
The chamois is something that does OK, but not my favorite. I was interested to see how memory foam does for absorbing pressure on long rides and I'm finding I don't love it. The chamois has two higher spots for the sit bones but it's almost cut like it has straight edges (as if cut with a cookie cutter) rather than tapering them down for multiple thicknesses like so many other shorts do today. Consequently, they don't always sit perfectly as you move around on the saddle. Additionally, it has a deep center channel that has minimal padding. This becomes a problem for me because I move around along the entire length of my saddle and when I sit up front, it's like there's almost no padding there. The fact that I ride in a fairly aggressive position also means the chamois sits too far back for my preference.
If you're one of those people that sits more upright and don't move around much on the saddle you may enjoy these. For me, they're just ok.
