Wednesday is Surly Bikes’ latest iteration of the fatbike. Starting with the Pugsley and the Moonlander bikes, then bringing out the Ice Cream Truck a few years later- in the meantime inventing the 29+ standard with the Krampus and ECR bikes- Surly appears to be looking for the sweet spot in the crowded fatbike market. The fact that every bike maker now has a fatbike in the line means that there are new standards for components such as hubs and bottom brackets that are specific to the unique requirements of fatbikes, and the Wednesday takes advantage of the resultant economies of scale.
There’s Fat and There’s Fat
The Wednesday comes stock with Surly’s 80mm wide My Other Brother Darryl rims which will fit either the stock 3.8″ tires or up to 4.6″ tires. If swapping to the bigger tires all that needs to be done is to slide the rear wheel back in the horizontal dropout for clearance; the fork is wide enough for the fatter tires. Rather than offsetting the rear triangle and wheel in order to use a traditional 135mm rear hub, à the Pugsley, the Wednesday uses a 170-177 rear spacing, depending on what type of axle is being used; 10mm or 12mm. The front fork uses a 150 x 15mm thru axle. The bike will work well with a 100mm suspension for as well.
The head tube on this bike is over-sized at 44mm. I guess this is from the mountain bike industry because many suspension forks now come with tapered steer tubes and in order to retrofit a fatbike with a suspension fork, a bigger head tube is needed. Still, suspension on a bike with 4 to 5″ wide tires? Seems redundant and unnecessary. Using a Truvativ (SRAM) double chain ring lets Surly use a “standard” 100mm bottom bracket shell which still allows moving the chain out far enough to clear the big fat tires.
The Surly catalog says the “Wednesday sits in the middle of our ride-anywhere Pugsley and the modern trail geometry of the Ice Cream Truck”. I’m not sure what that means relative to ride characteristics, but the Wednesday and the Ice Cream Truck both have shorter seat tubes and longer effective top tubes as well as longer overall wheelbase for a given size than either the Pugsley or the Moonlander bikes. Apparently, also according to the Surly catalog, the ride of the Wednesday is similar to that of the Krampus, their 29+ bike.
