surly-ice-cream-truck-fat-bike, The Largest Tire Clearance on a Fat Bike FrameFrom 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 terrainModern trail bike standards like stealth dropper post routing, 44mm headtube, and thru-axlesClearance for a full 26" x 5" tire on 100mm rims Build Kit FramesetFrame - Surly Ice Cream Truck, 100% Surly 4130 Chromoly steel.Fork - Surly Ice Cream Truck, 1-1/8" straight steerer with tapered straight blade.Seatpost Clamp - Stainless 33.1 collar, Black ComponentsHeadset - Cane Creek 40Brakes - Tektro Gemini HD-M520Brake Levers - Tektro Gemini HD-M520Rotors - Tektro, 180/160Shifter - Shimano SLX SL-M7100Stem - Promax, 31.8mmHandlebar - Salsa Rustler without logoSaddle - WTB Volt 142Seatpost - 2-bolt 30.9mm DrivetrainCrankset - Race Face AEffect with DM30t Steel RingBottom Bracket - Race Face 100mmFront Derailleur - N/ARear Derailleur - Shimano SLX RD-M7100 12-SpeedCog or cogset - Shimano SLX CS-M7100 10-51t, 12-SpeedChain - KMC X12 NP/BK WheelsFront Hub - 150x15mm, Novatec, 32h, Thru-AxleRear Hub - 197x12mm, Novatec, 32h, Thru-Axle, with Shimano Microspline freehubRims - Surly My Other Brother Darryl, 80mm with speedholesTires - Surly Bud & Lou, 4.8", 120tpi, Tubeless Ready Geometry SIZESMMDLGXLReach405427449472Stack588598607616Head Tube Angle68Adeg68Adeg68Adeg68AdegHead Tube Length95105115125Seat Tube Length366419470521BB Drop60606060Wheelbase1105113111571182Chainstay Length440440440440Top Tube Length, Actual556573595623Top Tube Length, Effective585610635660Seat Tube Angle73Adeg73Adeg73Adeg73AdegStandover Height777803831860Stem Length60708090Stem Angle7Adeg7Adeg7Adeg7AdegHandlebar Width720780780780Crank Length170175175175Fork Length483483483483Fork Rake47474747*effective ST angle due to bent ST Frame SpecFrame Construction - 4130 Chromoly, Natch tubing, double-butted main triangle, trumpet flared tubes, TIG welded, ED coatedFork Construction - 4130 Chromoly, Natch tubing, double-butted tapered fork blades, TIG welded, ED coatedRear Dropout Configuration - Horizontal slotted with optional vertical dumpoutRear Hub Spacing12 x 197mm (Surly axle included)10 x 190mm with Surly 10/12 Adapter Washers (not included)Front Hub Spacing - 15 x 150mm (Surly axle included)Rear Brake - Disc - 51mm I.S.
