The new S-Works Carbon Rib Cage III keeps the 100% FACT carbon fiber construction of yesteryear, but it ups bottle retention for super rough roads. The split design also provides pre-load to hold bottles securely, while making bottle entry as easy as possible. 

• FACT carbon construction creates a splendid fusion of strength, optimal bottle retention, and light overall weight.
• Super-low bottle position improves the aerodynamic profile.
• Tuned compression design provides secure bottle retention with easy in-and-out accessibility.
• Weight: 24g
• Not recommended for MTB or Gravel
