Surly Bikes
Wednesday is a frame with a decade of Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of our other Omniterra bikes can and for the Wednesday, we borrowed elements from both our Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff and doesn’t feel sluggish when you have to ride back to the top.
While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. We gave it plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube, standard bottle mounts on the seat tube and underside of the down tube plus rack mounts on the frame and fork with fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. No rat’s nest here. It’s a lot to take in so read that again and you’ll understand, it’s just plain ready for action. We gave Wednesday its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm.
We wanted Wednesday to give you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8˝ tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6˝ tires on an 80mm rim. Wednesday is made out of our own proprietary 4130 CroMoly steel and is ED coated. ED coating is a process that leaves a coating that, externally, provides a solid foundation for paint while also providing an added layer of corrosion protection internally. However, we still recommend an additional treatment such as Frame Saver or Boeshield.
