The Shimano SLX/Deore drivetrain is reliable and built to last.

    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. The ECR is our answer to those sometimes.

    Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, we redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as we’re offering that size in both options. So way to just be average I guess.

    Other updates to the ECR include and are limited to: Gnot-Boost rear spacing with our updated Troll dropout and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 27.5+ sizes also feature two sets of Three-Pack bosses while the 29+ sizes have two water bottle mounts and one set of Three-Pack bosses. You’ve got a lot of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it. And sweet ground scores when you find them.

    Get loaded and go with the ECR!
