Our Go-To Bikepacking Bike

Sometimes the only way to break the humdrum of life is with a bike ride off the beaten path. Sometimes just for a quick overnighter, sometimes a month and half fully-loaded through nine countries. ECR is our answer to those sometimes.

As our flagship bikepacking rig, ECR is adaptable to frame bags for the minimalist approach, as well as racks and bags to maximize gear-hauling potential. ECR is most at home when your tour starts on dirt and gets more technical from there.

  • Two wheel platforms available: 27.5+ for frame sizes XS–M and 29+ for M–XL
  • All the accessory barnacles you could ever possibly ask for including rack and fender, multiple three-pack mounts and mid-blade.
  • Gnot-Boost rear spacing with Rohloff torque arm slot and Bill/Ted trailer mount
  • Clearance for 27.5" x 3" (XS–M) or 29” x 3” (M–XL) tires (with or without fenders)
