My how things have changed. When the Surly Pugsley rolled onto the scene nearly 10 years ago no one could have predicted (well, some probably did) that fat bikes would be as common as they are today. Riders are using them not just for Arctic exploration, but also for straight up mountain biking, which has shaped development of wheels, tires and frame geometries.
The latest Surly model builds on that experience with geometry that more closely models that of the popular Ice Cream Truck: slacker head tube angle, lower bottom bracket and shorter chainstays than the Pugsley. It’s also built around a 177 mm symmetrical rear end unlike the offset hubs on a Pugsley.
The fork is also a thru-axle, and spaced at 150 mm so it is an easy swap for a RockShox Bluto fork. Even the seat tube has routing for an internal dropper post. This is a mountain bike, through and through, but present are all the mounts and braze-ons your little heart can desire, so it would make an excellent expedition rig too.
Unlike the Ice Cream Truck the tubeset is lighter for a more forgiving ride, and the dropouts are fixed rather than using the interchangeable MDS system. The bottom bracket is 100 mm threaded, and the bike can fit “only” a 4.6-inch tire on 80 mm rim. Speaking of rims, Surly has a new tubeless-compatible rim dubbed “My Other Brother Darryl,” which comes in a few different versions, depending on OE spec or aftermarket.
Surly says the new bike should go on sale later this fall for about $1,500.
