IBIS MOJO HDE WITH FLOAT X2 FRAMEFour generations of trail superiorityNow in its fourth generation, Ibis set out to completely redesign the geometry for the HD4 with focus on stability and speed. After much experimentation and real-world testing, Ibis landed on a 64.9 degree head tube angle, and increased the reach across the board. A redefined carbon layup, 30% stiffer upper link, and 40% greater stiffer lower link yield greater overall frame stiffness. Boost spacing adds to the overall ride quality by allowing the HD4 to fit up to 2.8" wide tires. Internal cable routing keeps the frame's appearance clean while protecting the cabling from the elements to keep your drivetrain running smooth.From the suspension standpoint, the current Mojo HD3 pedals superbly. Ibis didn't want to mess with such a dialed suspension design so they left the kinematics the same for the Mojo HD4. What Ibis did do, is engineer more progression into the shock leverage curve, allowing for more big-hit capability in very rough terrain. The travel went up a tiny bit, and it now has 153mm of rear travel. The bike is intended to fit a piggy-back rear air shock while still fitting a 22 oz water bottle in the frame. The Fox X2 rear shock is custom tuned to the bike with more progression engineered into the shock leverage curve, allowing for more big-hit capability in very rough terrain.REVIEWSPink Bike - "There's no doubt about it, the HD4 stomps on the HD3 when things get steeper and faster." - Mike LevyMTBR.com - "So far the Mojo HD4 has proven to be a weapon of mass PR destruction." - Jason SumnerFeaturesDW Link Suspension provides efficient pedaling while maintaining plushnessCarbon fiber monocoque frame and swingarm Lightweight, strong, and ready to be abused Internal cable routing protects cabling from the elements and keeps the frame looking sleek.Boost dropouts gives a boost to strength and riding characteristics ISCG tabs mount your favorite chain guideSPECIFICATIONSFrameIbis Monocoque Carbon Fiber, DW Link, 12x148mm dropouts, 153mm travelWheel Size27.5"Fork160mm-170mm, tapered steer recommendedHeadset IncludedN/AHeadtube DiameterTapered 44/56mmFront DerailleurN/ABottom BracketThreaded 68mmSeatpost31.6mmSeat Clamp35.0mm (included)Dropout Style12 x 148mm (Axle included)Accessory MountsISCG 05Cable routingInternalIntended UseTrail, All-mountainWeight-GEOMETRY (mm / inch)SizeSmallMediumLargeExtra LargeA: Seat Tube Length362 14.3393 15.5445 17.5483 19.0B: Effective Top Tube579 22.8604 23.8628 24.7658 25.9C: Stack570 22.4590 23.2605 23.8620 24.4D: Reach415 16.3435 17.1455 17.9480 18.9E: BB Height343 13.5343 13.5343 13.5343 13.5F: BB Drop12 0.512 0.512 0.512 0.5G: Head Tube Length87 3.4109 4.3126 5.0142 5.6H: Head Tube Angle64.9 deg64.9 deg64.9 deg64.9 degI: Seat Tube Angle74.0 deg74.0 deg74.0 deg74.0 degJ: Standover Height693 27.3715 28.1729 28.7757 29.8K: Chainstay Length430 16.9430 16.9430 16.9430 16.9L: Wheelbase1163 45.81192 46.91219 48.01251 49.3Suggested Rider Height5'0" - 5'5"5'4" - 5'9"5'9" - 6'2"6'0" - 6'6" | Ibis Mojo HD4 X2 Frame 2019 Fireball Red, Small, Carbon
