Item # RID004W

Well-suited for five-day rides.

Even in the age of graphene, we find that aluminum has its place in the world of cycling. That place is several dozens of miles beyond cellphone reception with nothing but freeze-dried camp food, a sleeping bag, and Ridley's X-Trail A20 105 Complete Bike for company. The frame's triple-butted 6061-T6 aluminum is heat-treated to further improve its fatigue resistance, so it's much better suited to the abuse of pannier-laden bikepacking than the latest wonder materials. Save the carbon climbing bike for five hour rides, and take the aluminum X-Trail for rides lasting five days.

Though the frame is aluminum, Ridley equips the X-Trail A20 with the same fork on the full carbon model. The legs of the Oryx Disc fork are shaped from a blend of 30t and 24t high-modulus carbon fiber, which add a bit of chatter-absorption while stiffening the front end in the event your bikepacking route leads straight up a steep fire road. The steerer is still aluminum, and the left leg is built-up in order to offset the twisting forces applied by disc brakes. The fork is equipped with a mountain-grade thru-axle, too, further reinforcing the overall structure against braking forces and the general lumps of all-terrain cycling.

The X-Trail's geometry is something of a melting pot, but the end result resembles a road bike more than a classic cyclocross bike like the X-Night. It's got a lower bottom bracket, shorter chainstays, and a stack/reach combination that leaves riders in less of a shoulder-intensive, slammed racing position. In contrast to its road racing frames, Ridley extended the X-Trail's head tube by 10mm, bringing riders into a more upright position to accommodate longer training rides rather than racing exclusively. It's only slightly more aggressive than the Fenix, in fact, but unlike its endurance road cousin, the X-Trail is designed to be run with tires up to 40mm.

  • An aluminum gravel bike built for bikepacking abuse
  • Long, stable geometry keeps its footing on gravel and washboard
  • A Shimano drivetrain built for life in the bush
  • 38mm Challenge tires represent the height of gravel rubber tech
  • Confident disc brake stopping power for fully loaded trips
  • Ridley's X-Trail series brings Belgian 'cross expertise to all-terrain cycling
