// GT GRADE ALUMINUM EXPERT 2020A GRADE ABOVEFor riders who want to explore the world on a bicycle, nothing beats having a gravel bike. With a gravel bike, you can continue riding when the pavement ends and the dirt begins. The paths you can take are unlimited. The GT Grade Aluminum Expert is engineered to take you further and faster. It is a versatile and compliant bike that is loaded with features. It starts with an aluminum frame that has an EnduRoad Triple Triangle Design that features Floating Seatstays that provide more vertical compliance for a more comfortable ride. The frame is also compatible with up to 42mm tires so you can get the maximum traction wherever you ride.The Expert model of the GT Grade Aluminum comes with a Shimano 105 2x11-speed drivetrain. The cassette on the rear has an excellent 11-34-tooth gear range that makes climbing much easier without sacrificing top-end speed. When it comes to descending, the Tektro mechanical disc brakes provide ample stopping power and work well in various conditions. WTB ST i23 rims are tubeless-ready and are paired with WTB Riddler tubeless-ready tires. This means you can ditch the tubes for a smoother ride, better traction, and fewer flats.FeaturesEnduRoad Triple Triangle Design with Floating Seatstays that enhance comfortShimano 105 drivetrain shifts smoothly and works well everywhereTektro mechanical disc brakes provide ample performance in various conditionsWide tire clearance with clearance for up to 42mm tiresRemovable fender bridge so you can keep your hindquarters cleanSPECIFICATIONSFrameAluminumForkCarbon FiberHeadsetFSA No.44 Integrated, Sealed BearingShiftersShimano 105, 2x11Front DerailleurShimano 105, Braze-OnRear DerailleurShimano 105 GSCranksetFSA Vero Pro, 48/32TBottom BracketCartridge, Square TaperPedals-ChainKMC X11CassetteShimano 105, 11-34TBrakesTektro Mechanical DiscWheelsetWTB ST i23 TCS, Tubeless ReadyTiresWTB Riddler, 700x37cHandlebarGT DropTune RS, 16deg FlareStem6061 AlloyBar TapeVelo Cork, 3mmSeatpost6061 Alloy Micro Adjust, 15mm OffsetSeatclamp-SaddleGT Grade Saddle, Steel RailsIntended UseGravel, AdventureWeight-Note: Components are subject to change without notice.METRICINCHGT Grade CarbonSize4851555861A: Seat Tube Length457494531568605B: Effective Top Tube545559574587602C: Stack546568590612634D: Reach378385394400408E: BB Height284286286289289F: BB Drop7573737070G: Head Tube Length119145160187210H: Head Tube Angle70.5 deg70.5 deg72.3 deg72.3 deg72.3 degI: Seat Tube Angle73 deg73 deg73 deg73 deg73 degJ: Standover Height731760791824851K: Chainstay Length445445445445445L: Wheelbase10421057105510701085GT Grade CarbonSize4851555861A: Seat Tube Length18.019.420.922.423.8B: Effective Top Tube21.522.022.623.123.7C: Stack21.522.423.224.125.0D: Reach14.915.215.515.716.1E: BB Height11.211.311.311.411.4F: BB Drop3.02.92.92.82.8G: Head Tube Length4.75.76.37.48.3H: Head Tube Angle70.5 deg70.5 deg72.3 deg72.3 deg72.3 degI: Seat Tube Angle73.0 deg73.0 deg73.0 deg73.0 deg73.0 degJ: Standover Height28.829.931.132.433.5K: Chainstay Length17.517.517.517.517.5L: Wheelbase41.041.641.542.142.7 | GT Grade Aluminum Expert 2020 48cm, Purple
