The ASSOS FI.Uno S5 is the all-round training and racing cycling bib short. It has the ASSOS' 6-panel Advanced Ergonomic Pattern Design (A.E.P.D.) with fewer seams. The overlocked seams give you excellent elasticity. The six panels with triple needed stitching, gives the performance minded rider bib shorts that cover your body like a second skin, making you aero and fast, while also keeping the pressure only in the right spots so you don’t get chafed and sore during the ride. This design is made for the ambitious rider because it optimizes muscle compression, reduces muscle fatigue and increases endurance. The back panel antistatic carbon fiber mesh wicks away that sweat and keeps you dry and cool in the summer or warm in the winter so you can maintain that high performance temperature that’s required when you are under the demands of a hard ride up a mountain or speeding through the corners in a criterium. In addition, the high-density foam pad protects all contact points because it has the right amount of padding in the right places. The T FI.Uno_S5 incorporates the new FI.Uno_S.5 insert, which is slightly thicker than the FI.13_S5 insert. The supple leg grippers hold your shorts snugly in place and are firm enough to support knee and leg warmers so they won’t creep up on your legs and bunch at the wrong time.
