This is what Surly has to say about their newly designed Fat Bike platforms, which will be ready for shipping this summer:
Ice Cream Truck is suspension corrected, will have thru-axle front and rear, MDS Dropout, Press fit BB, and Sram Hydro brakes – Additionally, the frame set uses the same swedged tubes as the Instigator for increased stiffness. The Pressfit BB offers a stiffer junction and allows for minimal chain stay manipulation and better clearance for wider tires. We use SRAM Hydro brakes because the DOT Fluid operates better at lower temps than mineral oil. The new rear end is symmetrically laced to a 197 thru axle hub for additional stiffness.
Ice Cream Truck Ops is an Optional Spec (not really an up spec) and is focused on building the bike in another vein of interest. It has the same frame set, but the spec is a little different. Narrower rims and tires, BB7 Brakes, same hubs front and rear, and all the same advantages and benefits of the new frame..
