What is the Surly Pack Rat? Well that’s a question a lot of people have been asking since a photo was leaked courtesy of Mr. Pubes a few weeks ago. Yes, it’s got rim brakes, and according to Surly, the geometry’s been optimized for riding with a front load and to reduce toe overlap.
That means it’ll ship with 650×42 tires on the larger sizes, and 26×1.5″ on the smaller sizes. With a 44mm fork offset it’s not a low trail bike, but it does have a relatively steep head angle compared to other bikes in those sizes – 74º on the 650b bikes and 72.5º on the 26″ bikes.
This whole conversation is a minefield, so… jump on in! Surly’s got a huge blog post up about it, so head on over there and dig in if you’re into it.
