Redesigning chainring tooth profiles doesn't generate much excitement until you actually experience the difference during a shift under load. Campagnolo rebuilt the Super Record 13 Chainring Set from the ground up, engineering a completely new tooth shape that grabs the chain faster during front derailleur action. That quicker engagement means cleaner shifts when you're putting down power, not just when you're soft-pedaling into a descent. The result is front shifting that feels more decisive than previous Campagnolo generations, addressing one of the few areas where the Italian groupset traditionally trailed its Japanese and American competitors.

The chainring set ships as a complete package with both inner and outer rings plus all necessary bolts, making it a straightforward swap whether you're replacing worn rings or changing your gear ratio. Campagnolo machines these from high-strength aluminum with an advanced surface treatment that extends wear life under demanding conditions. That treatment matters because chainring wear directly affects shift quality over time, and maintaining that crisp chain engagement depends on keeping the tooth profiles intact through thousands of kilometers.

Seven gear combinations span the full range from compact climbing setups to traditional racing configurations. The 45/29 pairing offers the lowest gearing for mountainous terrain, while 55/39 delivers the high-speed ratios that flat-course specialists and time trialists demand. Between those extremes, five additional combinations let you dial in exactly the gear spread that matches your riding style and terrain. That flexibility matters because Campagnolo designed the Super Record 13 system to pair any chainring combination with any of the four available cassettes, creating a modular drivetrain where you can genuinely customize your gear ratios rather than accepting predetermined pairings....
