Surly Ice Cream Truck Fat Bike

The Largest Tire Clearance on a Fat Bike Frame From log and root covered ribbons of twisty singletrack to miles of powdery snow or sandy beaches, Ice Cream Truck can handle it all. Hell, you could probably even hop over a grizzly if the situation arises. Probably. While we could certainly throw out terms like "confidence-inspiring" and "traction-laden" to describe Ice Cream Truck, those phrases are mostly bullshit, so we&';re not going to do that. We&';re not here to inspire you, and we didn&';t laden it with anything. What we did do was design a monolith of a trail bike that doesn&';t give two shits about what&';s in front of it. Long toptube, short seatstays, and a 68-degree headtube angle makes it tight and maneuverable on fast, technical terrain Modern trail bike standards like stealth dropper post routing, 44mm headtube, and thru-axles Clearance for a full 26" x 5" tire on 100mm rims Build Kit Frameset Frame - Surly Ice Cream Truck, 100% Surly 4130 Chromoly steel.
