BREZZA nano is an ultra narrow variant of BREZZA II aimed at competitors who spend almost all their race in an aero tuck for example triathletes or track specialists who don't need to wrangle the bike. Shortening the basebar to 30 cm width cuts weight and reduces frontal area, improving aerodynamics. In other respects BREZZA nano shares BREZZA II's specification. Shimano Di2 compatibility is introduced. Carbon fiber compact cradles and S bend extensions are standard. There's a full range of adjustment for athletes of diverse physiques. Straight, ski bend, and VV Shape deep S extensions are also available as 3T Accessories. BREZZA nano meets the UCI rules on 3:1 form factor.
