Bikemonger says... Take the amazing 27.5+/29+ platform, tweek it for long distance and hauling loads, and you have the awesome ECR. Dave the mechanic had one of these, with dynamo hub, USB charger, light rig, luggage, Moloko bars and a Rohloff, and described it has his zombie apocalypse bike. One of these and Swiss army knife and you could go on forever without ever needing civilisation or to be civilised.

Surly says... 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.
