UCI Compliant 3:1, aerodynamic full carbon fiber wing has zero drop from clamp to brake extensions. Combined with a shorter reach, this design translates to better control.
Slim, sleek risers fine-tune armrest/extension height to get a perfect blend of aerodynamics, power and comfort.
Used to prevent twisting of spokes while truing the wheel. It is also used to tighten the valve extender to the valve.
