Overview
The Largest Tire Clearance on a Fat Bike Frame
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.
Features
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
