My GO-TO Bibshort!!
by Tracy

It took me a long time to switch from shorts to Bibshorts but I have to say that Castell's Free Aero Race Bibshort made it easy! In fact this is my second pair. They are comfortable, even after a 100 mile ride. What made me hesitant to change was having to take off my jersey to use the ladies room but its really no big deal. Quick and easy.

Best Bibs even for a newb!

I had a off brand bib thinking it wouldn't make a difference. Then one day on a long 3hr+ ride, I couldnt take it. Ordered the Castelli bib and went on a 6hr ride with NO issues! Loved it!

Amazing shorts

I love these so much that I'm making custom shorts and using these. They're amazing quality. A little tighter fitting so consider that when sizing.

This is my first bib short and I love them!

The feel of the fabric is amazing and the chamois is comfortable and fit perfectly. I am still getting used to taking off my jersey to use the restroom. But my time in the saddle was awesome, no sore butt after the ride! Yes, I am a fan!

Amazing bibs!

I am a tough customer when it comes to bibs. I can guarantee that I am the pickiest around. The Free Aero Race 4 is PERFECT. There is no shifting, bunching, pinching or other annoyances with these. Super compressive without the dreaded sausage leg. Breathable fabric and minimal branding, so that one doesn't become a moving billboard. Chamois is top notch!!
