Show Description

The durability of the Fenix alloy meets the game-changing power of disc brakes. The A20 is built around a triple-butted aluminum frame with diamond-shaped tubing for long-term durability. Its skinny, flat seat stays take the buzz out of gravel or less-than-ideal road surfaces. Like Ridley's carbon fibre models, the tapered head tube shaves grams and boosts stiffness, while the carbon fork improves ride quality. As for those disc brakes? TRP Spyre mechanical calipers hit the sweet spot between all-out power and excellent braking control. Wet, dry or muddy, you can expect consistent performance regardless of conditions. Rounding out this minty build is an assortment of Shimano Tiagra components for solid shifting performance and pro-peloton good looks.

  • Frame material is triple-butted hydroformed 6061-T6 aluminum.
  • Flat-sectioned seat stays boost comfort and eliminate road buzz.
  • Diamond-shaped tubes are impact-resistant, stiff and durable.
  • Oversized tapered head tube increases front-end stiffness and steering precision.
  • Shimano® Tiagra shifters, crank and derailleurs are consistent performers.
  • Aluminum 4ZA Stratos seatpost, stem, handlebar and other components.
  • Mechanical TRP Spyre disc brakes for excellent all-weather performance.
  • 4ZA CX Disc wheels are at home on the road or gravel grinding.
  • Internal cable routing is clean, aero and compatible with mechanical and electronic shifting.
  • Mechanical cable stopper can be removed for conversion to electronic shifting.
  • Continental Ultra Sport II tires are performance oriented with excellent puncture resistance.
  • Pedals sold separately.
  • Bikes are covered by MEC's Rocksolid Guarantee and Bike Service Agreement. You can bring your bike to any MEC Bike Shop for free adjustments and minor maintenance for a year after purchase.
  • Ridley was born in Flanders, Belgium, a region infamous for harsh cycling conditions. Against this backdrop, Ridley engineers, tests and refines its frame construction, race technology, tube profiles, and its own branded component line, 4ZA.
