Like the Ogre, ECR can run racks, fenders and disc brakes simultaneously, front and rear. It's compatible with singlespeed, full derailleur and IGH drivetrains (it even features a dedicated Rohloff torque arm mount) because the rear dropouts are just like those on our Ogre and Troll frames. Run what you like. ECR has multiple mounts on the frame and fork for water bottle cages and larger gear cages, so you can bring lots of water, stove fuel, milk, a sleeping pad, small mammals or what have you.
It takes standard 34mm headsets and regular mountain bike hubs (100mm front and 135mm rear). It's designed for full length housing to keep out the elements and keep brakes braking and shifters shifting on long treks in rough conditions. The rigid fork can be swapped out for an 80mm suspension fork if you like, but this would mean you'd lose the extra carrying capacity of the stock fork, and you couldn't run a 3" tire and 50mm rim.
That last point is something to seriously ponder. ECR is of the 29+ category, a name we made up when we introduced the Krampus. 29+ means more width, more height, more traction, more cushion and more float than standard 29ers. The approach angle of such big tires (close to 31?) combined with the extra traction and float of high volume, low weight rubber make this bike extremely capable of going lots of places, from roads to trails to little-traveled back country. While the ECR borrows from Ogre, Krampus and even the Long Haul Trucker, its ride quality and capabilities are unique. It's a pack mule, a pedal-powered escape pod. Wherever you want to explore, this is the bike that can get you there.
