A Versatile All-Season Commuter BikeIf you're like us, your bike needs likely change by the day, week, month or year. Quite the adaptable little beast, Ogre can get you to your job during the week, then way out of town on the weekend. It's not sluggish on pavement or gravel and can also hold its own on singletrack.Ogre is designed to be the ultimate steel utility vehicle. It relishes in those "take-the-long-way-home-and-find-some-beverages-along-the-way" sort of commutes. Snow, sleet or sweltering humidity, this is an ideal year-round commuter bike. You can also haul enough crap on it that you don't even have to go home if you don't want to.All the barnacles you could ever possibly ask for including rack and fender, multiple three-pack mounts and mid-blade.Gnot-Boost rear spacing with Rohloff torque arm slot and Bill/Ted trailer mountClearance for 29" x 2.5" or 27.5" x 2.8" tires with fendersBuild KitFramesetFrame -100% Surly Chromoly Steel, Natch tubing, double-butted main triangle, TIG welded, E.D. coatedFork -100% Surly Chromoly Steel, Natch tubing, double-butted tapered fork blades, TIG welded, E.D. coatedSeatpost Clamp -Surly Stainless 30.0 ComponentsHeadset -Cane CreekBrakes -Avid BB5Brake Levers -Tektro FR5Rotors -160F/160RShifters -Microshift SL-M9605 Trail ProStem -Kalloy 31.8Handlebar -Salsa BendGrip/Tape -Velo BlackSaddle -WTB VoltSeatpost -ProMax 27.2x300 DrivetrainCrankset -SRAM NX 32tBottom Bracket -SRAM PowersplineFront Derailleur -N/ARear Derailleur -Microshift RD-M6205 with ClutchCog or cogset -OE 10-spd 11-48tChain -KMC X10 WheelsFront Hub -Novatec 9x100 QR, 6-bolt discRear Hub -Novatec 12x142 QR, 6-bolt discRims -WTB i29Tires -Surly ExtraTerrestrial 29x2.5" 60tpi, Tubeless Ready SIZESMMDLGXLReach395.5410.5427.6447Stack592603.4613632Head Tube Angle71.5Adeg72.0Adeg72.0Adeg72.0AdegHead Tube Length110120130150Seat Tube Length406.4457.2508558BB Drop68686868Wheelbase1049.41064.51084.61110Chainstay Length440440440440Top Tube Length, Actual545.6560.7580.2607Top Tube Length, Effective575595615640Seat Tube Angle73.0Adeg73.0Adeg73.0Adeg73.0AdegStandover Height763.5795.7824.5857.85Stem Length708090100Stem Angle7Adeg7Adeg7Adeg7AdegHandlebar Width700740740740Crank Length170175175175Fork Length447447447447Fork Rake43434343 Frame SpecFrame Construction - 4130 Chromoly, Natch tubing, double-butted main triangle, 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 Spacing"Gnot-Boost" 145mm12 x 142mm or 12 x 148mm (axle included)10 x 135mm with Surly 10/12 Adapter Washers (not included)Front Hub Spacing - 10 x 100mmRear Brake Disc - 51mm I.S.
