These bib shorts are unbelievable. I just picked up a pair. I previously used the Assos Fi.13 S5's and these are a marked upgrade. The quality is simply there. Both of the major changes (the kuku penthouse and the detached chamois) are SUBSTANTIAL improvements. When you try them on you do not quite notice this; however, both changes make riding in the saddle much more comfortable. The shorts fit true to size as well. I wore an XL in my S5's and an XL in these too. The other shorts, the Neopro and Equipe are also good but I would try each pair on because they do fit differently. Personally however, these are the best because they have the kuku penthouse, which actually works and is amazing.
