The Aeria Ultimate Race bracket is a sleeker and lighter option for the  Aeria Ultimate range of aerobars
  
At the pinnacle of the sport, grams count. So based on feedback  from professional cycling teams and elite triathletes we've created a  slimmed down version of the standard Aeria Ultimate bracket. The fit range is reduced with the smaller wing so this item is suited to riders utilising a narrow armrest
  
Fit Data: Armrest Hole width 154mm, Stack 42.6mm, Extension clamp 22.2mm
  
Weight: 180g
