Hard-riding roadies wear the Castelli Free Cycling Bibknicker because they understand the importance of long-lasting comfort and high-performance materials. The free bib doesn’t cover your front at all, allowing total upper body freedom. Windstopper X-LIte knee patches save you from the cold and Energia fabric provides killer return.

Castelli Free Knickers

Love Castelli Free bibs. The comfort and freedom of movement are great. The materials breath well and wick moisture away from your skin. I just wish they would do something different with the leg grippers on the knickers. They ride up as soon as you get on the bike and become nothing more than a pair of long shorts with a bunch of material around your knees. The shoulder straps need to be longer as well. They get uncomfortable after awhile unless you wear a shirt under them. Even when you up-size for euro styling the fit in the legs and seat doesn't match the shoulders unless you are very short. 6' 1" and 200lbs - XXL fits great except for the shoulder straps. I solved the problem by having 3" of elastic sewn into the shoulders, but for the price you shouldn't have to do custom alterations.

Responded on

Matt W,Hans, Carl, Thank you for the wonderfully detailed review. I agree. We spoke to the designers at Castelli about the strap matter presented on the reviews of this product. They are updating this product for 2010 to address the length of the straps, and it is a much better product now. Please remember that you can exchange or return the product if it doesn't fit right.

Few Issues

Be careful because white isn't exactly opaque. Seams fall apart and with shorts, they are too short. I am only about 5'10" and have short legs for my height and they are still too short. Digs in to shoulders. Chamoix is really nice, but way too many other issues.

Great bibs, but some issues

Castelli bib knickers and bib tights are generally awesome. The only issue with the knickers is they could be a little longer for me. I am 6' 4" and I order XL from Castelli (L from everyone else generally) and the knickers are a little shorter than I'd like. What I really need is a large tall or x-large tall, but Castelli doesn't make it (and neither does anyone else to my knowledge). Regardless, they are super comfortable and look great. The Castelli chamois is the best I have ever used by far.

Love these!

To be honest, I love all the Castelli free tights, yes you need to up your size a bit... but maybe because I'm of European decent , I have no problem with their sizing. I'm 6', 145 lbs and wear these in a medium. I actually lost 20 lbs, and I was wearing a medium when I was 165 lbs without an issue, just they were a bit tight on the legs... but what a great motivator to shed the excess weight . I wear domestic sizes in a small. But why do I love European sizes the most? Because they seem to be the only ones that make Jerseys to fit my 34" chest.

I would agree with some of your thoughts on this bib short. However, all "euro inspired" cycling apparel brands run very small. If you are 6'3 & 210lbs, I would recommend an XXXL from euro brands & consider a XXL from Pearl Izumi. I would take advantage of the great return policy & return it.

Bought Castelli bib tights

I bought Castelli bib tights from Chainlove that had previous bad reviews on backcountry. I should have listend, these are the same as the castelli bib tights. The shoulder straps dig into shoulders due to design. I'm 6'3 210 and bought XXL and they "barely" fit. Chamios is comfortable but shoulder straps bring most of your attention. Apparently Euro sizing doesn't include my size.
