Summary

The Specialized Tarmac is celebrated as a top-tier race bike, blending aerodynamics, lightweight design, and exceptional handling. It's noted for being faster than its predecessor, the Tarmac SL6, and as aerodynamic as the Venge, making it a versatile choice for racers. The bike's performance is further enhanced by its superb power transfer and cornering capabilities, though some reviews mention a firmer ride quality and higher price point as drawbacks.

Pros
  • More aerodynamic and faster than the Tarmac SL6

  • Lightweight with superb power transfer

  • Exceptional handling and cornering capabilities

  • Versatile for various racing conditions

  • Improved aerodynamics without weight gain

Cons
  • Firmer ride quality compared to the SL6

  • High price point

  • Integrated cockpit can complicate handlebar changes

  • Non-tubeless wheels in some configurations

Key Quotes
A handful of refinements and updates help the Tarmac maintain its position as the benchmark UCI-legal road-race bike.
