Here in Minneapolis, yesterday’s wallop of snow is a reminder that winter isn’t over just yet, and neither is fatbiking. Hoping to provide even more high quality tire options to the fatbiking public, 45NRTH has taken the wraps off of their biggest tire yet – the Dillinger 5. Based on the popular Dillinger studded fatbike tire, the Dillinger 5 is understandably 5 inches wide offering a studded tire choice for the newest ultra-fat bikes.

You’ll have to wait until this Fall to get your hands on some, but you can get the details after the break!

Even though the Dillinger 5 is technically a larger version of the 4, 45NRTH didn’t just stretch out the tire to fit. The 5 uses a slightly different tread pattern to give the larger tire improved grip to go along with the additional flotation and traction. Starting at the center of the tire the tread blocks get progressively taller as you work towards the shoulder of the tire which makes for a more squared tread profile. The center tread is kept low and tight for improved rolling resistance, while the paddle treads are widened for better grip in the snow.

Like the current Dillinger, the 5 will be offered in both a studded and studless tire that you can stud your self. in the case of the 5, both versions use a 120 tpi casing and will sell for $250 for the studded and $175 for the studless. Unlike the current Dillinger though, the 5 makes use of the new 45NRTH’s exclusive concave stud design. We got a first look at the new studs at Saddle Drive where David Gabrys explained that the concave studs offer twice the amount of bite in the ice thanks to the additional edge. To validate the concept David and team have been testing the studs on an indoor ice rink for months now, and are “astounded by the additional traction and control they offer. The studs consist of the concave carbide tip which is attached to an aluminum base that is pressed into each lug.

We’ll see if we can get some real weights while we’re here at Frostbike!
