Show Description

Designed with adventure in mind, this gravel grinder finds itself at home on bikepacking trips and on ride with a high ratio of gravel to pavement. With many of the features found on its carbon sibling (the X-Trail C), the X-Trail A draws on a high-performing aluminum frame that won't break the bank. Incredibly versatile, the geometry combines the nimbleness of a cyclocross ride with the high-speed stability and stiffness of a road bike. Massive clearance allows up to 700x42C or 650Bx55 tires to hammer the cyclocross circuit or go bikepacking by simply swapping out tires or wheels. The 1x11-speed SRAM Rival gruppo offers great reliability and performance at an affordable price. SRAM Rival hydraulic disc brakes provide stopping power with nuanced modulation. Smart details make this package a winner: asymmetric rear triangle for shock absorption and stiffness, hidden fender mounts for everyday usability, and carefully choosen 40mm wide tires for comfort on rough roads.

  • Triple-butted hydroformed aluminum frame is light, incredibly durable and represents huge value.
  • Lowered bottom bracket provides the high-speed stability needed for road riding.
  • Rear triangle design features uniquely shaped individual tubes for maximum stiffness, low weight and a comfortable degree of flex.
  • Bridgeless seat stay design improves tire clearance and allows the seat stay to independently flex for added shock absorption.
  • Oversized tapered head tube increases front end stiffness and steering precision.
  • Asymmetric carbon fibre fork features an aluminum steertube and integrated scuff guard.
  • 1x11 SRAM Rival gruppo yields precise shifting in an affordable package.
  • SRAM Rival hydraulic disc brakes with 160 and 140mm rotors front and back, respectively, provide power and modulation in any weather.
  • 4ZA Stratos stem, handlebars, and seatpost are designed with race performance in mind.
  • SRAM crank is equipped with a 44T chainring and is paired with an 11-42t cassette.
  • 12mm thru-axles front and rear provide outstanding stiffness, tracking and quick wheel changes.
  • Frame design allows for use of 700c or 650B wheels.
  • Tubeless-ready 4ZA Allroad Adventure wheels are designed to survive the rigours of cross, training, commuting and adventure riding.
  • 700c wheels with 40mm wide Donnelly X'Plor MSO tires are designed for everything that Mother Nature has to throw at you.
  • Hidden fender mounts add touring versatility.
  • 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.
